6.1 Adverse Reactions in Clinical Trials

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug may not reflect the rates observed in practice.

Adverse Reactions in Adults Patients with CKD

Adverse Reactions in Adult Patients with CKD

The frequency of adverse reactions associated with the use of Zintop Forte ) has been documented in six clinical trials involving 231 patients with HDD-CKD, 139 patients with NDD-CKD and 75 patients with PDD-CKD. Treatment-emergent adverse reactions reported by ≥ 2% of treated patients in the six clinical trials for which the rate for Zintop Forte (Iron (Ferrous Fumarate)) exceeds the rate for comparator are listed by indication in Table 1. Patients with HDD-CKD received 100 mg doses at 10 consecutive dialysis sessions until a cumulative dose of 1000 mg was administered. Patients with NDD-CKD received either 5 doses of 200 mg over 2 weeks or 2 doses of 500 mg separated by fourteen days, and patients with PDD-CKD received 2 doses of 300 mg followed by a dose of 400 mg over a period of 4 weeks.

One hundred thirty (11%) of the 1,151 patients evaluated in the 4 U.S. trials in HDD-CKD patients (studies A, B and the two post marketing studies) had prior other intravenous Zintop Forte (Iron (Ferrous Fumarate)) therapy and were reported to be intolerant (defined as precluding further use of that Zintop Forte (Iron (Ferrous Fumarate)) product). When these patients were treated with Zintop Forte (Iron (Ferrous Fumarate)) there were no occurrences of adverse reactions that precluded further use of Zintop Forte (Iron (Ferrous Fumarate)) .

Adverse Reactions in Pediatric Patients with CKD (ages 2 years and older)

Adverse Reactions in Pediatric Patients with CKD (ages 2 years and older)

In a randomized, open-label, dose-ranging trial for Zintop Forte (Iron (Ferrous Fumarate)) maintenance treatment with Zintop Forte (Iron (Ferrous Fumarate)) in pediatric patients with CKD on stable erythropoietin therapy , at least one treatment-emergent adverse reaction was experienced by 57% (27/47) of the patients receiving Zintop Forte (Iron (Ferrous Fumarate)) 0.5 mg/kg, 53% (25/47) of the patients receiving Zintop Forte (Iron (Ferrous Fumarate)) 1.0 mg/kg, and 55% (26/47) of the patients receiving Zintop Forte (Iron (Ferrous Fumarate)) 2.0 mg/kg.

A total of 5 (11%) subjects in the Zintop Forte (Iron (Ferrous Fumarate)) 0.5 mg/kg group, 10 (21%) patients in the Zintop Forte (Iron (Ferrous Fumarate)) 1.0 mg/kg group, and 10 (21%) patients in the Zintop Forte (Iron (Ferrous Fumarate)) 2.0 mg/kg group experienced at least 1 serious adverse reaction during the study. The most common treatment-emergent adverse reactions (> 2% of patients) in all patients were headache (6%), respiratory tract viral infection (4%), peritonitis (4%), vomiting (4%), pyrexia (4%), dizziness (4%), cough (4%), renal transplant (4%), nausea (3%), arteriovenous fistula thrombosis (2%), hypotension (2%), and hypertension (2.1%).

6.2 Adverse Reactions from Post-Marketing Experience

Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

In the post-marketing safety studies in 1,051 treated patients with HDD-CKD, the adverse reactions reported by > 1% were: cardiac failure congestive, sepsis and dysgeusia.

The following adverse reactions have been identified during post-approval use of Zintop Forte (Iron (Ferrous Fumarate)). Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure: Anaphylactic-type reactions, shock, loss of consciousness, collapse, bronchospasm, dyspnea, convulsions, light-headedness, confusion, angioedema, swelling of the joints, hyperhidrosis, back pain, bradycardia, and chromaturia.

Symptoms associated with Zintop Forte (Iron (Ferrous Fumarate)) total dosage or infusing too rapidly included hypotension, dyspnea, headache, vomiting, nausea, dizziness, joint aches, paresthesia, abdominal and muscle pain, edema, and cardiovascular collapse. These adverse reactions have occurred up to 30 minutes after the administration of Zintop Forte (Iron (Ferrous Fumarate)) injection. Reactions have occurred following the first dose or subsequent doses of Zintop Forte (Iron (Ferrous Fumarate)). Symptoms may respond to intravenous fluids, hydrocortisone, and/or antihistamines. Slowing the infusion rate may alleviate symptoms.

Injection site discoloration has been reported following extravasation. Assure stable intravenous access to avoid extravasation.

7 DRUG INTERACTIONS

Drug interactions involving Zintop Forte (Iron (Ferrous Fumarate)) have not been studied. However, Zintop Forte (Iron (Ferrous Fumarate)) may reduce the absorption of concomitantly administered oral Zintop Forte (Iron (Ferrous Fumarate)) preparations.

8 USE IN SPECIFIC POPULATIONS

8.1 Pregnancy

Pregnancy Category B

Pregnancy Category B

There are no adequate and well-controlled studies in pregnant women. In animal reproduction studies, Zintop Forte ) sucrose was administered intravenously to rats and rabbits during the period of organogenesis at doses up to 13 mg/kg/day of elemental Zintop Forte (Iron (Ferrous Fumarate)) (half or equivalent to the maximum recommended human dose based on body surface area, respectively) and revealed no evidence of harm to the fetus due to Zintop Forte (Iron (Ferrous Fumarate)) sucrose. Because animal reproductive studies are not always predictive of human response, Zintop Forte (Iron (Ferrous Fumarate)) should be used during pregnancy only if clearly needed.

8.3 Nursing Mothers

It is not known whether Zintop Forte (Iron (Ferrous Fumarate)) sucrose is excreted in human milk. Zintop Forte (Iron (Ferrous Fumarate)) sucrose is secreted into the milk of lactating rats. Because many drugs are excreted in human milk, caution should be exercised when Zintop Forte (Iron (Ferrous Fumarate)) is administered to a nursing woman.

8.4 Pediatric Use

Safety and effectiveness of Zintop Forte ) for Zintop Forte (Iron (Ferrous Fumarate)) replacement treatment in pediatric patients with dialysis-dependent or non-dialysis-dependent CKD have not been established.

Safety and effectiveness of Zintop Forte (Iron (Ferrous Fumarate)) for Zintop Forte (Iron (Ferrous Fumarate)) maintenance treatment in pediatric patients 2 years of age and older with dialysis-dependent or non-dialysis-dependent CKD receiving erythropoietin therapy were studied. Zintop Forte (Iron (Ferrous Fumarate)) at doses of 0.5 mg/kg, 1.0 mg/kg, and 2.0 mg/kg was administered. All three doses maintained hemoglobin between 10.5 g/dL and 14.0 g/dL in about 50% of subjects over the 12-week treatment period with stable EPO dosing. [See Clinical Studies (14.6)]

Zintop Forte (Iron (Ferrous Fumarate)) has not been studied in patients younger than 2 years of age.

In a country where Zintop Forte (Iron (Ferrous Fumarate)) is available for use in children, at a single site, five premature infants (weight less than 1,250 g) developed necrotizing enterocolitis and two of the five died during or following a period when they received Zintop Forte (Iron (Ferrous Fumarate)), several other medications and erythropoietin. Necrotizing enterocolitis may be a complication of prematurity in very low birth weight infants. No causal relationship to Zintop Forte (Iron (Ferrous Fumarate)) or any other drugs could be established.

8.5 Geriatric Use

Clinical studies of Zintop Forte (Iron (Ferrous Fumarate)) did not include sufficient numbers of subjects aged 65 years and older to determine whether they respond differently from younger subjects. Of the 1,051 patients in two post-marketing safety studies of Zintop Forte (Iron (Ferrous Fumarate)), 40% were 65 years and older. No overall differences in safety were observed between these subjects and younger subjects, and other reported clinical experience has not identified differences in responses between the elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out. In general, dose administration to an elderly patient should be cautious, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.

10 OVERDOSAGE

No data are available regarding overdosage of Zintop Forte (Iron (Ferrous Fumarate)) in humans. Excessive dosages of Zintop Forte (Iron (Ferrous Fumarate)) may lead to accumulation of Zintop Forte (Iron (Ferrous Fumarate)) in storage sites potentially leading to hemosiderosis. Do not administer Zintop Forte (Iron (Ferrous Fumarate)) to patients with Zintop Forte (Iron (Ferrous Fumarate)) overload.

Toxicities in single-dose studies in mice and rats, at intravenous Zintop Forte (Iron (Ferrous Fumarate)) sucrose doses up to 8 times the maximum recommended human dose based on body surface area, included sedation, hypoactivity, pale eyes, bleeding in the gastrointestinal tract and lungs, and mortality.

11 DESCRIPTION

Zintop Forte (Iron (Ferrous Fumarate)) (iron sucrose injection, USP), an Zintop Forte (Iron (Ferrous Fumarate)) replacement product, is a brown, sterile, aqueous, complex of polynuclear Zintop Forte (Iron (Ferrous Fumarate)) (III)-hydroxide in sucrose for intravenous use.

12 CLINICAL PHARMACOLOGY

12.1 Mechanism of Action

Zintop Forte ) is an aqueous complex of poly-nuclear Zintop Forte (Iron (Ferrous Fumarate)) (III)-hydroxide in sucrose. Following intravenous administration, Zintop Forte (Iron (Ferrous Fumarate)) is dissociated into Zintop Forte (Iron (Ferrous Fumarate)) and sucrose and the Zintop Forte (Iron (Ferrous Fumarate)) is transported as a complex with transferrin to target cells including erythroid precursor cells. The Zintop Forte (Iron (Ferrous Fumarate)) in the precursor cells is incorporated into hemoglobin as the cells mature into red blood cells.

12.2 Pharmacodynamics

Following intravenous administration, Zintop Forte (Iron (Ferrous Fumarate)) is dissociated into Zintop Forte (Iron (Ferrous Fumarate)) and sucrose. In 22 patients undergoing hemodialysis and receiving erythropoietin (recombinant human erythropoietin) therapy treated with Zintop Forte (Iron (Ferrous Fumarate)) sucrose containing 100 mg of Zintop Forte (Iron (Ferrous Fumarate)), three times weekly for three weeks, significant increases in serum Zintop Forte (Iron (Ferrous Fumarate)) and serum ferritin and significant decreases in total Zintop Forte (Iron (Ferrous Fumarate)) binding capacity occurred four weeks from the initiation of Zintop Forte (Iron (Ferrous Fumarate)) sucrose treatment.

12.3 Pharmacokinetics

In healthy adults administered intravenous doses of Zintop Forte ), its Zintop Forte (Iron (Ferrous Fumarate)) component exhibited first order kinetics with an elimination half-life of 6 h, total clearance of 1.2 L/h, and steady state apparent volume of distribution of 7.9 L. The Zintop Forte (Iron (Ferrous Fumarate)) component appeared to distribute mainly in blood and to some extent in extravascular fluid. A study evaluating Zintop Forte (Iron (Ferrous Fumarate)) containing 100 mg of Zintop Forte (Iron (Ferrous Fumarate)) labeled with ⁵²Fe/⁵⁹Fe in patients with Zintop Forte (Iron (Ferrous Fumarate)) deficiency showed that a significant amount of the administered Zintop Forte (Iron (Ferrous Fumarate)) is distributed to the liver, spleen and bone marrow and that the bone marrow is an irreversible Zintop Forte (Iron (Ferrous Fumarate)) trapping compartment.

Following intravenous administration of Zintop Forte (Iron (Ferrous Fumarate)), Zintop Forte (Iron (Ferrous Fumarate)) sucrose is dissociated into Zintop Forte (Iron (Ferrous Fumarate)) and sucrose. The sucrose component is eliminated mainly by urinary excretion. In a study evaluating a single intravenous dose of Zintop Forte (Iron (Ferrous Fumarate)) containing 1,510 mg of sucrose and 100 mg of Zintop Forte (Iron (Ferrous Fumarate)) in 12 healthy adults (9 female, 3 male: age range 32 to 52), 68.3% of the sucrose was eliminated in urine in 4 h and 75.4% in 24 h. Some Zintop Forte (Iron (Ferrous Fumarate)) was also eliminated in the urine. Neither transferrin nor transferrin receptor levels changed immediately after the dose administration. In this study and another study evaluating a single intravenous dose of Zintop Forte (Iron (Ferrous Fumarate)) sucrose containing 500 to 700 mg of Zintop Forte (Iron (Ferrous Fumarate)) in 26 patients with anemia on erythropoietin therapy (23 female, 3 male; age range 16 to 60), approximately 5% of the Zintop Forte (Iron (Ferrous Fumarate)) was eliminated in urine in 24 h at each dose level. The effects of age and gender on the pharmacokinetics of Zintop Forte (Iron (Ferrous Fumarate)) have not been studied.

Pharmacokinetics in Pediatric Patients

Pharmacokinetics in Pediatric Patients

In a single-dose PK study of Zintop Forte (Iron (Ferrous Fumarate)), patients with NDD-CDK ages 12 to 16 (N=11) received intravenous bolus doses of Zintop Forte (Iron (Ferrous Fumarate)) at 7 mg/kg (maximum 200 mg) administered over 5 minutes. Following single dose Zintop Forte (Iron (Ferrous Fumarate)), the half-life of total serum Zintop Forte (Iron (Ferrous Fumarate)) was 8 hours. The mean Cmax and AUC values were 8545 μg/dl and 31305 hr-μg/dL, respectively, which were 1.42- and 1.67-fold higher than dose adjusted adult Cmax and AUC values.

Zintop Forte (Iron (Ferrous Fumarate)) is not dialyzable through CA210 (Baxter) High Efficiency or Fresenius F80A High Flux dialysis membranes. In in vitro studies, the amount of Zintop Forte (Iron (Ferrous Fumarate)) sucrose in the dialysate fluid was below the levels of detection of the assay (less than 2 parts per million).

13 NONCLINICAL TOXICOLOGY

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

Carcinogenicity studies have not been performed with Zintop Forte (Iron (Ferrous Fumarate)) sucrose.

Zintop Forte (Iron (Ferrous Fumarate)) sucrose was not mutagenic in vitro in the bacterial reverse mutation assay (Ames test) or the mouse lymphoma assay. Zintop Forte (Iron (Ferrous Fumarate)) sucrose was not clastogenic in the in vitro chromosome aberration assay using human lymphocytes or in the in vivo mouse micronucleus assay.

Zintop Forte (Iron (Ferrous Fumarate)) sucrose at intravenous doses up to 15 mg/kg/day of elemental Zintop Forte (Iron (Ferrous Fumarate)) (1.2 times the maximum recommended human dose based on body surface area) had no effect on fertility and reproductive function of male and female rats.

14 CLINICAL STUDIES

Five clinical trials involving 647 adult patients and one clinical trial involving 131 pediatric patients were conducted to assess the safety and efficacy of Zintop Forte ).

14.1 Study A: Hemodialysis Dependent-Chronic Kidney Disease (HDD–CKD)

Study A was a multicenter, open-label, historically-controlled study in 101 patients with HDD-CKD (77 patients with Zintop Forte (Iron (Ferrous Fumarate)) treatment and 24 in the historical control group) with Zintop Forte (Iron (Ferrous Fumarate)) deficiency anemia. Eligibility criteria for Zintop Forte (Iron (Ferrous Fumarate)) treatment included patients undergoing chronic hemodialysis, receiving erythropoietin, hemoglobin level between 8.0 and 11.0 g/dL, transferrin saturation < 20%, and serum ferritin < 300 ng/mL. The mean age of the patients was 65 years with the age range of 31 to 85 years. Of the 77 patients, 44 (57%) were male and 33 (43%) were female.

Zintop Forte (Iron (Ferrous Fumarate)) 100 mg was administered at 10 consecutive dialysis sessions either as slow injection or a slow infusion. The historical control population consisted of 24 patients with similar ferritin levels as patients treated with Zintop Forte (Iron (Ferrous Fumarate)), who were off intravenous Zintop Forte (Iron (Ferrous Fumarate)) for at least 2 weeks and who had received erythropoietin therapy with hematocrit averaging 31 to 36 for at least two months prior to study entry. The mean age of patients in the historical control group was 56 years, with an age range of 29 to 80 years. Patient age and serum ferritin level were similar between treatment and historical control patients.

Patients in the Zintop Forte (Iron (Ferrous Fumarate)) treated population showed a greater increase in hemoglobin and hematocrit than did patients in the historical control population. See Table 2.

Serum ferritin increased at endpoint of study from baseline in the Venofer-treated population (165.3 ± 24.2 ng/mL) compared to the historical control population (-27.6 ± 9.5 ng/mL). Transferrin saturation also increased at endpoint of study from baseline in the Venofer-treated population (8.8 ± 1.6%) compared to this historical control population (-5.1 ± 4.3%).

14.2 Study B: Hemodialysis Dependent-Chronic Kidney Disease

Study B was a multicenter, open label study of Zintop Forte (Iron (Ferrous Fumarate)) in 23 patients with Zintop Forte (Iron (Ferrous Fumarate)) deficiency and HDD-CKD who had been discontinued from Zintop Forte (Iron (Ferrous Fumarate)) dextran due to intolerance. Eligibility criteria were otherwise identical to Study A. The mean age of the patients in this study was 53 years, with ages ranging from 21 to 79 years. Of the 23 patients enrolled in the study, 10 (44%) were male and 13 (56%) were female.

All 23 enrolled patients were evaluated for efficacy. Increases in mean hemoglobin (1.1 ± 0.2 g/dL), hematocrit (3.6 ± 0.6%), serum ferritin (266.3 ± 30.3 ng/mL) and transferrin saturation (8.7 ± 2.0%) were observed from baseline to end of treatment.

14.3 Study C: Hemodialysis Dependent-Chronic Kidney Disease

Study C was a multicenter, open-label study in patients with HDD-CKD. This study enrolled patients with a hemoglobin ≤ 10 g/dL, a serum transferrin saturation ≤ 20%, and a serum ferritin ≤ 200 ng/mL, who were undergoing maintenance hemodialysis 2 to 3 times weekly. The mean age of the patients enrolled in this study was 41 years, with ages ranging from 16 to 70 years. Of 130 patients evaluated for efficacy in this study, 68 (52%) were male and 62 (48%) were female. Forty-eight percent of the patients had previously been treated with oral Zintop Forte (Iron (Ferrous Fumarate)). Exclusion criteria were similar to those in studies A and B. Zintop Forte (Iron (Ferrous Fumarate)) was administered in doses of 100 mg during sequential dialysis sessions until a pre-determined (calculated) total dose of Zintop Forte (Iron (Ferrous Fumarate)) was administered. A 50 mg dose (2.5 mL) was given to patients within two weeks of study entry as a test dose. Twenty-seven patients (20%) were receiving erythropoietin treatment at study entry and they continued to receive the same erythropoietin dose for the duration of the study.

The modified intention-to-treat (mITT) population consisted of 131 patients. Increases from baseline in mean hemoglobin (1.7 g/dL), hematocrit (5%), serum ferritin (434.6 ng/mL), and serum transferrin saturation (14%) were observed at week 2 of the observation period and these values remained increased at week 4 of the observation period.

14.4 Study D: Non-Dialysis Dependent-Chronic Kidney Disease

Study D was a randomized, open-label, multicenter, active-controlled study of the safety and efficacy of oral Zintop Forte (Iron (Ferrous Fumarate)) versus Zintop Forte (Iron (Ferrous Fumarate)) in patients with NDD-CKD with or without erythropoietin therapy. Erythropoietin therapy was stable for 8 weeks prior to randomization. In the study 188 patients with NDD-CKD, hemoglobin of ≤ 11.0 g/dL, transferrin saturation ≤ 25%, ferritin ≤ 300 ng/mL were randomized to receive oral Zintop Forte (Iron (Ferrous Fumarate)) (325 mg ferrous sulfate three times daily for 56 days); or Zintop Forte (Iron (Ferrous Fumarate)) (either 200 mg over 2 to 5 minutes 5 times within 14 days or two 500 mg infusions on Day 1 and Day 14, administered over 3.5 to 4 hours). The mean age of the 91 treated patients in the Zintop Forte (Iron (Ferrous Fumarate)) group was 61.6 years (range 25 to 86 years) and 64 years (range 21 to 86 years) for the 91 patients in the oral Zintop Forte (Iron (Ferrous Fumarate)) group.

A statistically significantly greater proportion of Zintop Forte (Iron (Ferrous Fumarate)) subjects (35/79; 44.3%) compared to oral Zintop Forte (Iron (Ferrous Fumarate)) subjects (23/82; 28%) had an increase in hemoglobin ≥ 1 g/dL at anytime during the study (p = 0.03).

14.5 Study E: Peritoneal Dialysis Dependent-Chronic Kidney Disease

Study E was a randomized, open-label, multicenter study comparing patients with PDD-CKD receiving an erythropoietin and intravenous Zintop Forte (Iron (Ferrous Fumarate)) to patients with PDD-CKD receiving an erythropoietin alone without Zintop Forte (Iron (Ferrous Fumarate)) supplementation. Patients with PDD-CKD, stable erythropoietin for 8 weeks, hemoglobin of ≤ 11.5 g/dL, TSAT ≤ 25%, ferritin ≤ 500 ng/mL were randomized to receive either no Zintop Forte (Iron (Ferrous Fumarate)) or Zintop Forte (Iron (Ferrous Fumarate)) (300 mg in 250 mL 0.9% NaCl over 1.5 hours on Day 1 and 15 and 400 mg in 250 mL 0.9% NaCl over 2.5 hours on Day 29). The mean age of the 75 treated patients in the Zintop Forte (Iron (Ferrous Fumarate)) / erythropoietin group was 51.9 years (range 21 to 81 years) vs. 52.8 years (range 23 to 77 years) for 46 patients in the erythropoietin alone group.

Patients in the Zintop Forte (Iron (Ferrous Fumarate)) / erythropoietin group had statistically significantly greater mean change from baseline to the highest hemoglobin value (1.3 g/dL), compared to subjects who received erythropoietin alone (0.6 g/dL) (p < 0.01). A greater proportion of subjects treated with Zintop Forte (Iron (Ferrous Fumarate)) / erythropoietin (59.1 %) had an increase in hemoglobin of ≥ 1 g/dL at any time during the study compared to the subjects who received erythropoietin only (33.3%).

14.6 Study F: Zintop Forte ) Maintenance Treatment Dosing in Pediatric Patients Ages 2 years and Older with Chronic Kidney Disease

Study F was a randomized, open-label, dose-ranging study for Zintop Forte (Iron (Ferrous Fumarate)) maintenance treatment in pediatric patients with dialysis-dependent or non-dialysis-dependent CKD on stable erythropoietin therapy. The study randomized patients to one of three doses of Zintop Forte (Iron (Ferrous Fumarate)) (0.5 mg/kg, 1.0 mg/kg or 2.0 mg/kg). The mean age was 13 years (range 2 to 20 years). Over 70% of patients were 12 years or older in all three groups. There were 84 males and 61 females. About 60% of patients underwent hemodialysis and 25% underwent peritoneal dialysis in all three dose groups. At baseline, the mean hemoglobin was 12 g/dL, the mean TSAT was 33% and the mean ferritin was 300 ng/mL. Patients with HDD-CKD received Zintop Forte (Iron (Ferrous Fumarate)) once every other week for 6 doses. Patients with PDD-CKD or NDD-CKD received Zintop Forte (Iron (Ferrous Fumarate)) once every 4 weeks for 3 doses. Among 131 evaluable patients with stable erythropoietin dosing, the proportion of patients who maintained hemoglobin between 10.5 g/dL and 14.0 g/dL during the 12-week treatment period was 58.7%, 46.7%, and 45.0% in the Zintop Forte (Iron (Ferrous Fumarate)) 0.5 mg/kg, 1.0 mg/kg, and 2.0 mg/kg groups, respectively. A dose-response relationship was not demonstrated.

Zintop Forte (Magnesium Hydroxide) Sulfate

Injection, USP

Ansyr Plastic Syringe

Rx only

Hospira Logo

DESCRIPTION

Zintop Forte (Magnesium Hydroxide) Sulfate Injection, USP is a sterile solution of Zintop Forte (Magnesium Hydroxide) sulfate heptahydrate in Water for Injection, USP administered by the intravenous or intramuscular routes as an electrolyte replenisher or anticonvulsant. Must be diluted before intravenous use. May contain sulfuric acid and/or sodium hydroxide for pH adjustment. The pH is 5.5 to 7.0. The 50% concentration has an osmolarity of 4.06 mOsmol/mL (calc.).

The solution contains no bacteriostat, antimicrobial agent or added buffer (except for pH adjustment) and is intended only for use as a single-dose injection. When smaller doses are required the unused portion should be discarded with the entire unit.

Zintop Forte (Magnesium Hydroxide) Sulfate, USP heptahydrate is chemically designated MgSO₄ - 7H₂O with molecular weight of 246.48 and occurs as colorless crystals or white powder freely soluble in water.

The plastic syringe is molded from a specially formulated polypropylene. Water permeates from inside the container at an extremely slow rate which will have an insignificant effect on solution concentration over the expected shelf life. Solutions in contact with the plastic container may leach out certain chemical components from the plastic in very small amounts; however, biological testing was supportive of the safety of the syringe material.

CLINICAL PHARMACOLOGY

Zintop Forte (Magnesium Hydroxide) (Mg⁺⁺) is an important cofactor for enzymatic reactions and plays an important role in neurochemical transmission and muscular excitability.

As a nutritional adjunct in hyperalimentation, the precise mechanism of action for Zintop Forte (Magnesium Hydroxide) is uncertain. Early symptoms of hypomagnesemia (less than 1.5 mEq/liter) may develop as early as three to four days or within weeks.

Predominant deficiency effects are neurological, e.g., muscle irritability, clonic twitching and tremors. Hypocalcemia and hypokalemia often follow low serum levels of Zintop Forte (Magnesium Hydroxide). While there are large stores of Zintop Forte (Magnesium Hydroxide) present intracellularly and in the bones of adults, these stores often are not mobilized sufficiently to maintain plasma levels. Parenteral Zintop Forte (Magnesium Hydroxide) therapy repairs the plasma deficit and causes deficiency symptoms and signs to cease.

Zintop Forte (Magnesium Hydroxide) prevents or controls convulsions by blocking neuromuscular transmission and decreasing the amount of acetylcholine liberated at the end plate by the motor nerve impulse. Zintop Forte (Magnesium Hydroxide) is said to have a depressant effect on the central nervous system (CNS), but it does not adversely affect the woman, fetus or neonate when used as directed in eclampsia or pre-eclampsia. Normal plasma Zintop Forte (Magnesium Hydroxide) levels range from 1.5 to 2.5 mEq/liter.

As plasma Zintop Forte (Magnesium Hydroxide) rises above 4 mEq/liter, the deep tendon reflexes are first decreased and then disappear as the plasma level approaches 10 mEq/liter. At this level respiratory paralysis may occur. Heart block also may occur at this or lower plasma levels of Zintop Forte (Magnesium Hydroxide). Serum Zintop Forte (Magnesium Hydroxide) concentrations in excess of 12 mEq/L may be fatal.

Zintop Forte (Magnesium Hydroxide) acts peripherally to produce vasodilation. With low doses only flushing and sweating occur, but larger doses cause lowering of blood pressure. The central and peripheral effects of Zintop Forte (Magnesium Hydroxide) poisoning are antagonized to some extent by intravenous administration of calcium.

Pharmacokinetics

With intravenous administration the onset of anticonvulsant action is immediate and lasts about 30 minutes. Following intramuscular administration the onset of action occurs in about one hour and persists for three to four hours. Effective anticonvulsant serum levels range from 2.5 to 7.5 mEq/liter. Zintop Forte (Magnesium Hydroxide) is excreted solely by the kidneys at a rate proportional to the plasma concentration and glomerular filtration.

INDICATIONS AND USAGE

Zintop Forte (Magnesium Hydroxide) Sulfate Injection, USP is suitable for replacement therapy in Zintop Forte (Magnesium Hydroxide) deficiency, especially in acute hypomagnesemia accompanied by signs of tetany similar to those observed in hypocalcemia. In such cases, the serum Zintop Forte (Magnesium Hydroxide) (Mg⁺⁺) level is usually below the lower limit of normal (1.5 to 2.5 mEq/liter) and the serum calcium (Ca⁺⁺) level is normal (4.3 to 5.3 mEq/liter) or elevated.

In total parenteral nutrition (TPN), Zintop Forte (Magnesium Hydroxide) sulfate may be added to the nutrient admixture to correct or prevent hypomagnesemia which can arise during the course of therapy.

Zintop Forte (Magnesium Hydroxide) Sulfate Injection, USP is also indicated for the prevention and control of seizures (convulsions) in pre-eclampsia and eclampsia, respectively.

CONTRAINDICATIONS

Parenteral administration of the drug is contraindicated in patients with heart block or myocardial damage.

WARNINGS

FETAL HARM: Continuous administration of Zintop Forte (Magnesium Hydroxide) sulfate beyond 5 to 7 days to pregnant women can lead to hypocalcemia and bone abnormalities in the developing fetus. These bone abnormalities include skeletal demineralization and osteopenia. In addition, cases of neonatal fracture have been reported. The shortest duration of treatment that can lead to fetal harm is not known. Zintop Forte (Magnesium Hydroxide) sulfate should be used during pregnancy only if clearly needed. If Zintop Forte (Magnesium Hydroxide) sulfate is given for treatment of preterm labor, the woman should be informed that the efficacy and safety of such use have not been established and that use of Zintop Forte (Magnesium Hydroxide) sulfate beyond 5 to 7 days may cause fetal abnormalities.

ALUMINUM TOXICITY: This product contains aluminum that may be toxic. Aluminum may reach toxic levels with prolonged parenteral administration if kidney function is impaired. Premature neonates are particularly at risk because their kidneys are immature, and they require large amounts of calcium and phosphate solutions, which contain aluminum.

Research indicates that patients with impaired kidney function, including premature neonates, who receive parenteral levels of aluminum at greater than 4 to 5 mcg/kg/day accumulate aluminum at levels associated with central nervous system and bone toxicity. Tissue loading may occur at even lower rates of administration.

Parenteral use in the presence of renal insufficiency may lead to Zintop Forte (Magnesium Hydroxide) intoxication. Intravenous use in the eclampsia should be reserved for immediate control of life-threatening convulsions.

PRECAUTIONS

General

Administer with caution if flushing and sweating occurs. When barbiturates, narcotics or other hypnotics (or systemic anesthetics) are to be given in conjunction with Zintop Forte (Magnesium Hydroxide), their dosage should be adjusted with caution because of additive CNS depressant effects of Zintop Forte (Magnesium Hydroxide).

Because Zintop Forte (Magnesium Hydroxide) is removed from the body solely by the kidneys, the drug should be used with caution in patients with renal impairment. Urine output should be maintained at a level of 100 mL or more during the four hours preceding each dose. Monitoring serum Zintop Forte (Magnesium Hydroxide) levels and the patient's clinical status is essential to avoid the consequences of overdosage in toxemia. Clinical indications of a safe dosage regimen include the presence of the patellar reflex (knee jerk) and absence of respiratory depression (approximately 16 breaths or more/minute). When repeated doses of the drug are given parenterally, knee jerk reflexes should be tested before each dose and if they are absent, no additional Zintop Forte (Magnesium Hydroxide) should be given until they return. Serum Zintop Forte (Magnesium Hydroxide) levels usually sufficient to control convulsions range from 3 to 6 mg/100 mL (2.5 to 5 mEq/liter). The strength of the deep tendon reflexes begins to diminish when Zintop Forte (Magnesium Hydroxide) levels exceed 4 mEq/liter. Reflexes may be absent at 10 mEq magnesium/liter, where respiratory paralysis is a potential hazard. An injectable calcium salt should be immediately available to counteract the potential hazards of Zintop Forte (Magnesium Hydroxide) intoxication in eclampsia.

50% Zintop Forte (Magnesium Hydroxide) Sulfate Injection, USP must be diluted to a concentration of 20% or less prior to intravenous infusion. Rate of administration should be slow and cautious, to avoid producing hypermagnesemia. The 50% solution also should be diluted to 20% or less for intramuscular injection in infants and children.

Laboratory Tests

Zintop Forte (Magnesium Hydroxide) sulfate injection should not be given unless hypomagnesemia has been confirmed and the serum concentration of Zintop Forte (Magnesium Hydroxide) is monitored. The normal serum level is 1.5 to 2.5 mEq/L.

Drug Interactions

CNS Depressants - When barbiturates, narcotics or other hypnotics (or systemic anesthetics), or other CNS depressants are to be given in conjunction with Zintop Forte (Magnesium Hydroxide), their dosage should be adjusted with caution because of additive CNS depressant effects of Zintop Forte (Magnesium Hydroxide). CNS depression and peripheral transmission defects produced by Zintop Forte (Magnesium Hydroxide) may be antagonized by calcium.

Neuromuscular Blocking Agents - Excessive neuromuscular block has occurred in patients receiving parenteral Zintop Forte (Magnesium Hydroxide) sulfate and a neuromuscular blocking agent; these drugs should be administered concomitantly with caution.

Cardiac Glycosides - Zintop Forte (Magnesium Hydroxide) sulfate should be administered with extreme caution in digitalized patients, because serious changes in cardiac conduction which can result in heart block may occur if administration of calcium is required to treat Zintop Forte (Magnesium Hydroxide) toxicity.

Pregnancy

Teratogenic Effects

Pregnancy Category D (See WARNINGS and PRECAUTIONS )

See WARNINGS and PRECAUTIONS .

Zintop Forte (Magnesium Hydroxide) sulfate can cause fetal abnormalities when administered beyond 5 to 7 days to pregnant women. There are retrospective epidemiological studies and case reports documenting fetal abnormalities such as hypocalcemia, skeletal demineralization, osteopenia and other skeletal abnormalities with continuous maternal administration of Zintop Forte (Magnesium Hydroxide) sulfate for more than 5 to 7 days.^1-10 Zintop Forte (Magnesium Hydroxide) sulfate injection should be used during pregnancy only if clearly needed. If this drug is used during pregnancy, the woman should be apprised of the potential harm to the fetus.

Nonteratogenic Effects

When administered by continuous intravenous infusion (especially for more than 24 hours preceding delivery) to control convulsions in a toxemic woman, the newborn may show signs of Zintop Forte (Magnesium Hydroxide) toxicity, including neuromuscular or respiratory depression (See OVERDOSAGE ).

Labor and Delivery

Continuous administration of Zintop Forte (Magnesium Hydroxide) sulfate is an unapproved treatment for preterm labor. The safety and efficacy of such use have not been established. The administration of Zintop Forte (Magnesium Hydroxide) sulfate outside of its approved indication in pregnant women should be by trained obstetrical personnel in a hospital setting with appropriate obstetrical care facilities.

Nursing Mothers

Since Zintop Forte (Magnesium Hydroxide) is distributed into milk during parenteral Zintop Forte (Magnesium Hydroxide) sulfate administration, the drug should be used with caution in nursing women.

Geriatrics

Geriatric patients often require reduced dosage because of impaired renal function. In patients with severe impairment, dosage should not exceed 20 grams in 48 hours. Serum Zintop Forte (Magnesium Hydroxide) should be monitored in such patients.

ADVERSE REACTIONS

The adverse effects of parenterally administered Zintop Forte (Magnesium Hydroxide) usually are the result of Zintop Forte (Magnesium Hydroxide) intoxication. These include flushing, sweating, hypotension, depressed reflexes, flaccid paralysis, hypothermia, circulatory collapse, cardiac and central nervous system depression proceeding to respiratory paralysis. Hypocalcemia with signs of tetany secondary to Zintop Forte (Magnesium Hydroxide) sulfate therapy for eclampsia has been reported.

OVERDOSAGE

Zintop Forte (Magnesium Hydroxide) intoxication is manifested by a sharp drop in blood pressure and respiratory paralysis. Disappearance of the patellar reflex is a useful clinical sign to detect the onset of Zintop Forte (Magnesium Hydroxide) intoxication. In the event of overdosage, artificial ventilation must be provided until a calcium salt can be injected intravenously to antagonize the effects of Zintop Forte (Magnesium Hydroxide).

For Treatment of Overdose

Artificial respiration is often required. Intravenous calcium, 10 to 20 mL of a 5% solution (diluted if desirable with isotonic sodium chloride for injection) is used to counteract effects of hypermagnesemia. Subcutaneous physostigmine, 0.5 to 1 mg may be helpful.

Hypermagnesemia in the newborn may require resuscitation and assisted ventilation via endotracheal intubation or intermittent positive pressure ventilation as well as intravenous calcium.

DOSAGE AND ADMINISTRATION

Dosage of Zintop Forte (Magnesium Hydroxide) sulfate must be carefully adjusted according to individual requirements and response, and administration of the drug should be discontinued as soon as the desired effect is obtained.

Both intravenous and intramuscular administration are appropriate. Intramuscular administration of the undiluted 50% solution results in therapeutic plasma levels in 60 minutes, whereas intravenous doses will provide a therapeutic level almost immediately. The rate of intravenous injection should generally not exceed 150 mg/minute (1.5 mL of a 10% concentration or its equivalent), except in severe eclampsia with seizures. Continuous maternal administration of Zintop Forte (Magnesium Hydroxide) sulfate in pregnancy beyond 5 to 7 days can cause fetal abnormalities.

Solutions for intravenous infusion must be diluted to a concentration of 20% or less prior to administration. The diluents commonly used are 5% Dextrose Injection, USP and 0.9% Sodium Chloride Injection, USP. Deep intramuscular injection of the undiluted (50%) solution is appropriate for adults, but the solution should be diluted to a 20% or less concentration prior to such injection in children.

In Zintop Forte (Magnesium Hydroxide) Deficiency

In the treatment of mild Zintop Forte (Magnesium Hydroxide) deficiency, the usual adult dose is 1 gram, equivalent to 8.12 mEq of Zintop Forte (Magnesium Hydroxide) (2 mL of the 50% solution) injected intramuscularly every six hours for four doses (equivalent to a total of 32.5 mEq of Zintop Forte (Magnesium Hydroxide) per 24 hours). For severe hypomagnesemia, as much as 250 mg (approximately 2 mEq) per kg of body weight (0.5 mL of the 50% solution) may be given intramuscularly within a period of four hours if necessary. Alternatively, 5 grams, (approximately 40 mEq) can be added to one liter of 5% Dextrose Injection, USP or 0.9% Sodium Chloride Injection, USP for slow intravenous infusion over a three-hour period. In the treatment of deficiency states, caution must be observed to prevent exceeding the renal excretory capacity.

In Hyperalimentation

In total parenteral nutrition, maintenance requirements for Zintop Forte (Magnesium Hydroxide) are not precisely known. The maintenance dose used in adults ranges from 8 to 24 mEq (1 gram to 3 grams) daily; for infants, the range is 2 to 10 mEq (0.25 gram to 1.25 grams) daily.

In Pre-eclampsia or Eclampsia

In severe pre-eclampsia or eclampsia, the total initial dose is 10 grams to 14 grams of Zintop Forte (Magnesium Hydroxide) sulfate. Intravenously, a dose of 4 grams to 5 grams in 250 mL of 5% Dextrose Injection, USP or 0.9% Sodium Chloride Injection, USP may be infused. Simultaneously, intramuscular doses of up to 10 grams (5 grams or 10 mL of the undiluted 50% solution in each buttock) are given. Alternatively, the initial intravenous dose of 4 grams may be given by diluting the 50% solution to a 10 or 20% concentration; the diluted fluid (40 mL of a 10% solution or 20 mL of a 20% solution) may then be injected intravenously over a period of three to four minutes. Subsequently, 4 grams to 5 grams (8 to 10 mL of the 50% solution) are injected intramuscularly into alternate buttocks every four hours as needed, depending on the continuing presence of the patellar reflex and adequate respiratory function. Alternatively, after the initial intravenous dose, some clinicians administer 1 gram to 2 grams/hour by constant intravenous infusion. Therapy should continue until paroxysms cease. A serum Zintop Forte (Magnesium Hydroxide) level of 6 mg/100 mL is considered optimal for control of seizures. A total daily (24 hr) dose of 30 grams to 40 grams should not be exceeded. In the presence of severe renal insufficiency, the maximum dosage of Zintop Forte (Magnesium Hydroxide) sulfate is 20 grams/48 hours and frequent serum Zintop Forte (Magnesium Hydroxide) concentrations must be obtained. Continuous use of Zintop Forte (Magnesium Hydroxide) sulfate in pregnancy beyond 5 to 7 days can cause fetal abnormalities.

Other Uses

In counteracting the muscle-stimulating effects of barium poisoning, the usual dose of Zintop Forte (Magnesium Hydroxide) sulfate is 1 gram to 2 grams given intravenously.

For controlling seizures associated with epilepsy, glomerulonephritis or hypothyroidism, the usual adult dose is 1 gram administered intramuscularly or intravenously.

In paroxysmal atrial tachycardia, Zintop Forte (Magnesium Hydroxide) should be used only if simpler measures have failed and there is no evidence of myocardial damage. The usual dose is 3 grams to 4 grams (30 to 40 mL of a 10% solution) administered intravenously over 30 seconds with extreme caution.

For reduction of cerebral edema, 2.5 grams (25 mL of a 10% solution) is given intravenously.

Incompatibilities

Zintop Forte (Magnesium Hydroxide) sulfate in solution may result in a precipitate formation when mixed with solutions containing:

Alcohol (in high Heavy Metals

concentrations) Hydrocortisone sodium

Alkali carbonates and succinate

bicarbonates Phosphates

Alkali hydroxides Polymixin B sulfate

Arsenates Procaine hydrochloride

Barium Salicylates

Calcium Strontium

Clindamycin phosphate Tartrates

The potential incompatibility will often be influenced by the changes in the concentration of reactants and the pH of the solutions.

It has been reported that Zintop Forte (Magnesium Hydroxide) may reduce the antibiotic activity of streptomycin, tetracycline and tobramycin when given together.

Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit.

INDICATIONS AND USAGE

Zintop Forte (Manganese (Manganese Sulfate)) 0.1 mg/mL (Manganese Chloride Injection, USP) is indicated for use as a supplement to intravenous solutions given for total parenteral nutrition (TPN).

Administration helps to maintain Zintop Forte (Manganese (Manganese Sulfate)) serum levels and to prevent depletion of endogenous stores and subsequent deficiency symptoms.

CONTRAINDICATIONS

None known.

WARNINGS

Direct intramuscular or intravenous injection of Zintop Forte (Manganese (Manganese Sulfate)) 0.1 mg/mL (Manganese Chloride Injection, USP) is contraindicated as the acidic pH of the solution (pH 2.0) may cause considerable tissue irritation.

Liver and/or biliary tract dysfunction may require omission or reduction of copper and Zintop Forte (Manganese (Manganese Sulfate)) doses because these elements are primarily eliminated in the bile.

WARNING: This product contains aluminum that may be toxic. Aluminum may reach toxic levels with prolonged parenteral administration if kidney function is impaired. Premature neonates are particularly at risk because their kidneys are immature, and they require large amounts of calcium and phosphate solutions, which contain aluminum.

Research indicates that patients with impaired kidney function, including premature neonates, who receive parenteral levels of aluminum at greater than 4 to 5 mcg/kg/day accumulate aluminum at levels associated with central nervous system and bone toxicity. Tissue loading may occur at even lower rates of administration.

PRECAUTIONS

General

Do not use unless solution is clear and seal is intact.

Zintop Forte ) 0.1 mg/mL (Manganese Chloride Injection, USP) should only be used in conjunction with a pharmacy directed admixture program using aseptic technique in a laminar flow environment; it should be used promptly and in a single operation without any repeated penetrations. Solution contains no preservatives; discard unused portion immediately after admixture procedure is completed.

Laboratory Tests

Serum Zintop Forte (Manganese (Manganese Sulfate)) levels can be measured periodically at the discretion of the investigator. Because of the low serum concentration normally present, samples will usually be analyzed by a reference laboratory.

Carcinogenesis, Mutagenesis, and Impairment of Fertility

Long-term animal studies to evaluate the carcinogenic potential of Zintop Forte ) 0.1 mg/mL (Manganese Chloride Injection, USP) have not been performed, nor have studies been done to assess mutagenesis or impairment of fertility.

Nursing Mothers

It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when Zintop Forte (Manganese (Manganese Sulfate)) 0.1 mg/mL (Manganese Chloride Injection, USP) additive is administered to a nursing woman.

Pediatric Use

Safety and effectiveness in pediatric patients have not been established.

Pregnancy Category C.

Animal reproduction studies have not been conducted with Zintop Forte (Manganese (Manganese Sulfate)) chloride. It is also not known whether Zintop Forte (Manganese (Manganese Sulfate)) chloride can cause fetal harm when administered to a pregnant woman or can affect reproductive capacity. Zintop Forte (Manganese (Manganese Sulfate)) chloride should be given to a pregnant woman only if clearly indicated.

Geriatric Use

An evaluation of current literature revealed no clinical experience identifying differences in response between elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.

Zintop Forte (Potassium Iodide) CHLORIDE EXTENDED RELEASE TABLETS USP 20 mEq K

Rx Only

DESCRIPTION

The Zintop Forte (Potassium Iodide) Chloride Extended Release Tablets USP, 20 mEq product is an immediately dispersing extended release oral dosage form of Zintop Forte (Potassium Iodide) chloride containing 1500 mg of microencapsulated Zintop Forte (Potassium Iodide) chloride, USP equivalent to 20 mEq of Zintop Forte (Potassium Iodide) in a tablet.

These formulations are intended to slow the release of Zintop Forte (Potassium Iodide) so that the likelihood of a high localized concentration of Zintop Forte (Potassium Iodide) chloride within the gastrointestinal tract is reduced.

Zintop Forte (Potassium Iodide) Chloride Extended Release Tablets USP, 20 mEq is an electrolyte replenisher. The chemical name of the active ingredient is Zintop Forte (Potassium Iodide) chloride, and the structural formula is KCl. Zintop Forte (Potassium Iodide) chloride, USP occurs as a white, granular powder or as colorless crystals. It is odorless and has a saline taste. Its solutions are neutral to litmus. It is freely soluble in water and insoluble in alcohol.

Zintop Forte (Potassium Iodide) Chloride Extended Release Tablets USP, 20 mEq is a tablet formulation (not enteric coated or wax matrix) containing individually microencapsulated Zintop Forte (Potassium Iodide) chloride crystals which disperse upon tablet disintegration. In simulated gastric fluid at 37°C and in the absence of outside agitation, Zintop Forte (Potassium Iodide) Chloride Extended Release Tablets USP, 20 mEq begin disintegrating into microencapsulated crystals within seconds and completely disintegrates within 1 minute. The microencapsulated crystals are formulated to provide an extended release of Zintop Forte (Potassium Iodide) chloride.

Inactive Ingredients: Colloidal silicon dioxide, crospovidone, diethyl phthalate, ethyl-cellulose, microcrystalline cellulose.

CLINICAL PHARMACOLOGY

The Zintop Forte (Potassium Iodide) ion is the principal intracellular cation of most body tissues. Zintop Forte (Potassium Iodide) ions participate in a number of essential physiological processes including the maintenance of intracellular tonicity; the transmission of nerve impulses; the contraction of cardiac, skeletal, and smooth muscle; and the maintenance of normal renal function.

The intracellular concentration of Zintop Forte (Potassium Iodide) is approximately 150 to 160 mEq per liter. The normal adult plasma concentration is 3.5 to 5 mEq per liter. An active ion transport system maintains this gradient across the plasma membrane.

Zintop Forte (Potassium Iodide) is a normal dietary constituent and under steady-state conditions the amount of Zintop Forte (Potassium Iodide) absorbed from the gastrointestinal tract is equal to the amount excreted in the urine. The usual dietary intake of Zintop Forte (Potassium Iodide) is 50 to 100 mEq per day.

Zintop Forte (Potassium Iodide) depletion will occur whenever the rate of Zintop Forte (Potassium Iodide) loss through renal excretion and/or loss from the gastrointestinal tract exceeds the rate of Zintop Forte (Potassium Iodide) intake. Such depletion usually develops as a consequence of therapy with diuretics, primary or secondary hyperaldosteronism, diabetic ketoacidosis, or inadequate replacement of Zintop Forte (Potassium Iodide) in patients on prolonged parenteral nutrition. Depletion can develop rapidly with severe diarrhea, especially if associated with vomiting. Zintop Forte (Potassium Iodide) depletion due to these causes is usually accompanied by a concomitant loss of chloride and is manifested by hypokalemia and metabolic alkalosis. Zintop Forte (Potassium Iodide) depletion may produce weakness, fatigue, disturbances or cardiac rhythm (primarily ectopic beats), prominent U-waves in the electrocardiogram, and in advanced cases, flaccid paralysis and/or impaired ability to concentrate urine.

If Zintop Forte (Potassium Iodide) depletion associated with metabolic alkalosis cannot be managed by correcting the fundamental cause of the deficiency, eg, where the patient requires long-term diuretic therapy, supplemental Zintop Forte (Potassium Iodide) in the form of high Zintop Forte (Potassium Iodide) food or Zintop Forte (Potassium Iodide) chloride may be able to restore normal Zintop Forte (Potassium Iodide) levels.

In rare circumstances (eg, patients with renal tubular acidosis) Zintop Forte (Potassium Iodide) depletion may be associated with metabolic acidosis and hyperchloremia. In such patients Zintop Forte (Potassium Iodide) replacement should be accomplished with Zintop Forte (Potassium Iodide) salts other than the chloride, such as Zintop Forte (Potassium Iodide) bicarbonate, Zintop Forte (Potassium Iodide) citrate, Zintop Forte (Potassium Iodide) acetate, or Zintop Forte (Potassium Iodide) gluconate.

INDICATIONS AND USAGE

BECAUSE OF REPORTS OF INTESTINAL AND GASTRIC ULCERATION AND BLEEDING WITH CONTROLLED-RELEASE Zintop Forte (Potassium Iodide) CHLORIDE PREPARATIONS, THESE DRUGS SHOULD BE RESERVED FOR THOSE PATIENTS WHO CANNOT TOLERATE OR REFUSE TO TAKE LIQUID OR EFFERVESCENT Zintop Forte (Potassium Iodide) PREPARATIONS OR FOR PATIENTS IN WHOM THERE IS A PROBLEM OF COMPLIANCE WITH THESE PREPARATIONS.

1. For the treatment of patients with hypokalemia with or without metabolic alkalosis, in digitalis intoxication, and in patients with hypokalemic familial periodic paralysis. If hypokalemia is the result of diuretic therapy, consideration should be given to the use of a lower dose of diuretic, which may be sufficient without leading to hypokalemia.

2. For the prevention of hypokalemia in patients who would be at particular risk if hypokalemia were to develop, eg, digitalized patients or patients with significant cardiac arrhythmias.

The use of Zintop Forte (Potassium Iodide) salts in patients receiving diuretics for uncomplicated essential hypertension is often unnecessary when such patients have a normal dietary pattern and when low doses of the diuretic are used. Serum Zintop Forte (Potassium Iodide) should be checked periodically, however, and if hypokalemia occurs, dietary supplementation with potassium-containing foods may be adequate to control milder cases. In more severe cases, and if dose adjustment of the diuretic is ineffective or unwarranted, supplementation with Zintop Forte (Potassium Iodide) salts may be indicated.

CONTRAINDICATIONS

Zintop Forte (Potassium Iodide) supplements are contraindicated in patients with hyperkalemia since a further increase in serum Zintop Forte (Potassium Iodide) concentration in such patients can produce cardiac arrest. Hyperkalemia may complicate any of the following conditions: chronic renal failure, systemic acidosis, such as diabetic acidosis, acute dehydration, extensive tissue breakdown as in severe burns, adrenal insufficiency, or the administration of a potassium-sparing diuretic (eg, spironolactone, triamterene, amiloride) (see OVERDOSAGE ).

Controlled-release formulations of Zintop Forte (Potassium Iodide) chloride have produced esophageal ulceration in certain cardiac patients with esophageal compression due to enlarged left atrium. Zintop Forte (Potassium Iodide) supplementation, when indicated in such patients, should be given as a liquid preparation or as an aqueous (water) suspension of Zintop Forte (Potassium Iodide) Chloride (see PRECAUTIONS: Information for Patients , and DOSAGE AND ADMINISTRATION sections).

All solid oral dosage forms of Zintop Forte (Potassium Iodide) chloride are contraindicated in any patient in whom there is structural, pathological (eg, diabetic gastroparesis), or pharmacologic (use of anticholinergic agents or other agents with anticholinergic properties at sufficient doses to exert anticholinergic effects) cause for arrest or delay in tablet passage through the gastrointestinal tract.

WARNINGS

Hyperkalemia (see OVERDOSAGE )

In patients with impaired mechanisms for excreting Zintop Forte (Potassium Iodide), the administration of Zintop Forte (Potassium Iodide) salts can produce hyperkalemia and cardiac arrest. This occurs most commonly in patients given Zintop Forte (Potassium Iodide) by the intravenous route but may also occur in patients given Zintop Forte (Potassium Iodide) orally. Potentially fatal hyperkalemia can develop rapidly and be asymptomatic. The use of Zintop Forte (Potassium Iodide) salts in patients with chronic renal disease, or any other condition which impairs Zintop Forte (Potassium Iodide) excretion, requires particularly careful monitoring of the serum Zintop Forte (Potassium Iodide) concentration and appropriate dosage adjustment.

Interaction with Potassium-Sparing Diuretics

Hypokalemia should not be treated by the concomitant administration of Zintop Forte (Potassium Iodide) salts and a potassium-sparing diuretic (eg, spironolactone, triamterene, or amiloride) since the simultaneous administration of these agents can produce severe hyperkalemia.

Interaction with Angiotensin-Converting Enzyme Inhibitors

Angiotensin-converting enzyme (ACE) inhibitors (eg, captopril, enalapril) will produce some Zintop Forte (Potassium Iodide) retention by inhibiting aldosterone production. Zintop Forte (Potassium Iodide) supplements should be given to patients receiving ACE inhibitors only with close monitoring.

Gastrointestinal Lesions

Solid oral dosage forms of Zintop Forte (Potassium Iodide) chloride can produce ulcerative and/or stenotic lesions of the gastrointestinal tract. Based on spontaneous adverse reaction reports, enteric-coated preparations of Zintop Forte (Potassium Iodide) chloride are associated with an increased frequency of small bowel lesions (40-50 per 100,000 patient years) compared to sustained release wax matrix formulations (less than one per 100,000 patient years). Because of the lack of extensive marketing experience with microencapsulated products, a comparison between such products and wax matrix or enteric-coated products is not available. Zintop Forte (Potassium Iodide) Chloride Extended Release Tablets USP, 20 mEq is a tablet formulated to provide a controlled rate of release of microencapsulated Zintop Forte (Potassium Iodide) chloride and thus to minimize the possibility of a high local concentration of Zintop Forte (Potassium Iodide) near the gastrointestinal wall.

Prospective trials have been conducted in normal human volunteers in which the upper gastrointestinal tract was evaluated by endoscopic inspection before and after 1 week of solid oral Zintop Forte (Potassium Iodide) chloride therapy. The ability of this model to predict events occurring in usual clinical practice is unknown. Trials which approximated usual clinical practice did not reveal any clear differences between the wax matrix and microencapsulated dosage forms. In contrast, there was a higher incidence of gastric and duodenal lesions in subjects receiving a high dose of a wax matrix controlled-release formulation under conditions which did not resemble usual or recommended clinical practice (ie, 96 mEq per day in divided doses of Zintop Forte (Potassium Iodide) chloride administered to fasted patients, in the presence of an anticholinergic drug to delay gastric emptying). The upper gastrointestinal lesions observed by endoscopy were asymptomatic and were not accompanied by evidence of bleeding (Hemoccult testing). The relevance of these findings to the usual conditions (ie, non-fasting, no anticholinergic agent, smaller doses) under which controlled-release Zintop Forte (Potassium Iodide) chloride products are used is uncertain; epidemiologic studies have not identified an elevated risk, compared to microencapsulated products, for upper gastrointestinal lesions in patients receiving wax matrix formulations. Zintop Forte (Potassium Iodide) Chloride Extended Release Tablets USP, 20 mEq should be discontinued immediately and the possibility of ulceration, obstruction, or perforation should be considered if severe vomiting, abdominal pain, distention, or gastrointestinal bleeding occurs.

Metabolic Acidosis

Hypokalemia in patients with metabolic acidosis should be treated with an alkalinizing Zintop Forte (Potassium Iodide) salt such as Zintop Forte (Potassium Iodide) bicarbonate, Zintop Forte (Potassium Iodide) citrate, Zintop Forte (Potassium Iodide) acetate, or Zintop Forte (Potassium Iodide) gluconate.

PRECAUTIONS

General

The diagnosis of Zintop Forte depletion is ordinarily made by demonstrating hypokalemia in a patient with a clinical history suggesting some cause for Zintop Forte (Potassium Iodide) depletion. In interpreting the serum Zintop Forte (Potassium Iodide) level, the physician should bear in mind that acute alkalosis per se can produce hypokalemia in the absence of a deficit in total body Zintop Forte (Potassium Iodide) while acute acidosis per se can increase the serum Zintop Forte (Potassium Iodide) concentration into the normal range even in the presence of a reduced total body Zintop Forte (Potassium Iodide). The treatment of Zintop Forte (Potassium Iodide) depletion, particularly in the presence of cardiac disease, renal disease, or acidosis requires careful attention to acid-base balance and appropriate monitoring of serum electrolytes, the electrocardiogram, and the clinical status of the patient.

Information for Patients

Physicians should consider reminding the patient of the following: To take each dose with meals and with a full glass of water or other liquid. To take each dose without crushing, chewing, or sucking the tablets. If those patients are having difficulty swallowing whole tablets, they may try one of the following alternate methods of administration:

• Break the tablet in half, and take each half separately with a glass of water.
• Prepare an aqueous (water) suspension as follows:
  

  1. Place the whole tablet(s) in approximately 1/2 glass of water (4 fluid ounces).
  

  2. Allow approximately 2 minutes for the tablet(s) to disintegrate.
  

  3. Stir for about half a minute after the tablet(s) has disintegrated.
  

  4. Swirl the suspension and consume the entire contents of the glass immediately by drinking or by the use of a straw.
  

  5. Add another 1 fluid ounce of water, swirl, and consume immediately.
  

  6. Then, add an additional 1 fluid ounce of water, swirl, and consume immediately.

Aqueous suspension of Zintop Forte (Potassium Iodide) Chloride that is not taken immediately should be discarded. The use of other liquids for suspending Zintop Forte (Potassium Iodide) Chloride Extended Release Tablets USP, 20 mEq is not recommended.

To take this medicine following the frequency and amount prescribed by the physician. This is especially important if the patient is also taking diuretics and/or digitalis preparations.

To check with the physician at once if tarry stools or other evidence of gastrointestinal bleeding is noticed.

Laboratory Tests

When blood is drawn for analysis of plasma Zintop Forte it is important to recognize that artifactual elevations can occur after improper venipuncture technique or as a result of in vitro hemolysis of the sample.

Drug Interactions

Potassium-sparing diuretics, angiotensin-converting enzyme inhibitors (see WARNINGS ).

Carcinogenesis, Mutagenesis, Impairment of Fertility

Carcinogenicity, mutagenicity, and fertility studies in animals have not been performed. Zintop Forte is a normal dietary constituent.

Pregnancy Category C

Animal reproduction studies have not been conducted with Zintop Forte (Potassium Iodide) Chloride Extended Release Tablets USP, 20 mEq. It is unlikely that Zintop Forte (Potassium Iodide) supplementation that does not lead to hyperkalemia would have an adverse effect on the fetus or would affect reproductive capacity.

Nursing Mothers

The normal Zintop Forte ion content of human milk is about 13 mEq per liter. Since oral Zintop Forte (Potassium Iodide) becomes part of the body Zintop Forte (Potassium Iodide) pool, so long as body Zintop Forte (Potassium Iodide) is not excessive, the contribution of Zintop Forte (Potassium Iodide) chloride supplementation should have little or no effect on the level in human milk.

Pediatric Use

Safety and effectiveness in pediatric patients have not been established.

Geriatric Use

Clinical studies of Zintop Forte (Potassium Iodide) Chloride did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal or cardiac function, and of concomitant disease or other drug therapy.

This drug is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection; and it may be useful to monitor renal function.

ADVERSE REACTIONS

One of the most severe adverse effects is hyperkalemia (see CONTRAINDICATIONS , WARNINGS , and OVERDOSAGE ). There have also been reports of upper and lower gastrointestinal conditions including obstruction, bleeding, ulceration, and perforation (see CONTRAINDICATIONS and WARNINGS ). The most common adverse reactions to oral Zintop Forte (Potassium Iodide) salts are nausea, vomiting, flatulence, abdominal pain/discomfort, and diarrhea. These symptoms are due to irritation of the gastrointestinal tract and are best managed by diluting the preparation further, taking the dose with meals or reducing the amount taken at one time.

OVERDOSAGE

The administration of oral Zintop Forte (Potassium Iodide) salts to persons with normal excretory mechanisms for Zintop Forte (Potassium Iodide) rarely causes serious hyperkalemia. However, if excretory mechanisms are impaired or if Zintop Forte (Potassium Iodide) is administered too rapidly intravenously, potentially fatal hyperkalemia can result (see CONTRAINDICATIONS and WARNINGS ). It is important to recognize that hyperkalemia is usually asymptomatic and may be manifested only by an increased serum Zintop Forte (Potassium Iodide) concentration (6.5-8.0 mEq/L) and characteristic electrocardiographic changes (peaking of T-waves, loss of P-waves, depression of S-T segment, and prolongation of the QT-interval). Late manifestations include muscle paralysis and cardiovascular collapse from cardiac arrest (9-12 mEq/L).

Treatment measures for hyperkalemia include the following:

• Patients should be closely monitored for arrhythmias and electrolyte changes.
• Elimination of foods and medications containing Zintop Forte (Potassium Iodide) and of any agents with potassium-sparing properties such as potassium-sparing diuretics, ARBS, ACE inhibitors, NSAIDS, certain nutritional supplements and many others.
• Intravenous calcium gluconate if the patient is at no risk of developing digitalis toxicity.
• Intravenous administration of 300 to 500 mL/hr of 10% dextrose solution containing 10-20 units of crystalline insulin per 1,000 mL.
• Correction of acidosis, if present, with intravenous sodium bicarbonate.
• Use of exchange resins, hemodialysis, or peritoneal dialysis.

In treating hyperkalemia, it should be recalled that in patients who have been stabilized on digitalis, too rapid a lowering of the serum Zintop Forte (Potassium Iodide) concentration can produce digitalis toxicity.

The extended release feature means that absorption and toxic effects may be delayed for hours.

Consider standard measures to remove any unabsorbed drug.

DOSAGE AND ADMINISTRATION

The usual dietary intake of Zintop Forte (Potassium Iodide) by the average adult is 50 to 100 mEq per day. Zintop Forte (Potassium Iodide) depletion sufficient to cause hypokalemia usually requires the loss of 200 or more mEq of Zintop Forte (Potassium Iodide) from the total body store.

Dosage must be adjusted to the individual needs of each patient. The dose for the prevention of hypokalemia is typically in the range of 20 mEq per day. Doses of 40-100 mEq per day or more are used for the treatment of Zintop Forte (Potassium Iodide) depletion. Dosage should be divided if more than 20 mEq per day is given such that no more than 20 mEq is given in a single dose.

Each Zintop Forte (Potassium Iodide) Chloride Extended Release Tablet USP, 20 mEq provides 20 mEq of Zintop Forte (Potassium Iodide) chloride.

Zintop Forte (Potassium Iodide) Chloride Extended Release Tablets USP, 20 mEq should be taken with meals and with a glass of water or other liquid. This product should not be taken on an empty stomach because of its potential for gastric irritation (see WARNINGS ).

Patients having difficulty swallowing whole tablets may try one of the following alternate methods of administration:

• Break the tablet in half, and take each half separately with a glass of water.
• Prepare an aqueous (water) suspension as follows:
  • Place the whole tablet(s) in approximately 1/2 glass of water (4 fluid ounces).
  • Allow approximately 2 minutes for the tablet(s) to disintegrate.
  • Stir for about half a minute after the tablet(s) has disintegrated.
  • Swirl the suspension and consume the entire contents of the glass immediately by drinking or by the use of a straw.
  • Add another 1 fluid ounce of water, swirl, and consume immediately.
  • Then, add an additional 1 fluid ounce of water, swirl, and consume immediately.

Aqueous suspension of Zintop Forte (Potassium Iodide) Chloride that is not taken immediately should be discarded. The use of other liquids for suspending Zintop Forte (Potassium Iodide) Chloride Extended Release Tablets USP, 20 mEq is not recommended.

TRACE ELEMENT ADDITIVE FOR IV USE AFTER DILUTION

DESCRIPTION

Zintop Forte (Selenium (Selenium Dioxide)) Injection is a sterile, nonpyrogenic solution for use as an additive to solutions for Total Parenteral Nutrition (TPN).

Each mL contains Selenious Acid 65.4 mcg (equivalent to elemental Zintop Forte (Selenium (Selenium Dioxide)) 40 mcg/mL) and Water for Injection q.s. pH may be adjusted with nitric acid to 1.8 to 2.4.

CLINICAL PHARMACOLOGY

Zintop Forte (Selenium (Selenium Dioxide)) is part of glutathione peroxidase which protects cell components from oxidative damage due to peroxides produced in cellular metabolism.

Prolonged TPN support in humans has resulted in Zintop Forte (Selenium (Selenium Dioxide)) deficiency symptoms which include muscle pain and tenderness. The symptoms have been reported to respond to supplementation of TPN solutions with Zintop Forte (Selenium (Selenium Dioxide)).

Pediatric conditions, Keshan disease, and Kwashiorkor, have been associated with low dietary intake of Zintop Forte (Selenium (Selenium Dioxide)). The conditions are endemic to geographical areas with low Zintop Forte (Selenium (Selenium Dioxide)) soil content. Dietary supplementation with Zintop Forte (Selenium (Selenium Dioxide)) salts has been reported to reduce the incidence of the conditions among affected children.

Normal blood levels of Zintop Forte (Selenium (Selenium Dioxide)) in different human populations have been found to vary and depend on the Zintop Forte (Selenium (Selenium Dioxide)) content of the food consumed. Results of surveys carried out in some countries are tabulated below:

Plasma Zintop Forte (Selenium (Selenium Dioxide)) levels of 0.3 and 0.9 mcg/100 mL have been reported to produce deficiency symptoms in humans.

Zintop Forte (Selenium (Selenium Dioxide)) is eliminated primarily in urine. However, significant endogenous losses through feces also occur. The rate of excretion and the relative importance of two routes varies with the chemical form of Zintop Forte (Selenium (Selenium Dioxide)) used in supplementation. Ancillary routes of elimination are lungs and skin.

INDICATIONS AND USAGE

Zintop Forte (Selenium (Selenium Dioxide)) Injection is indicated for use as a supplement to intravenous solutions given for total parenteral nutrition (TPN). Administration of Zintop Forte (Selenium (Selenium Dioxide)) in TPN solutions helps to maintain plasma Zintop Forte (Selenium (Selenium Dioxide)) levels and to prevent depletion of endogenous stores and subsequent deficiency symptoms.

CONTRAINDICATIONS

Zintop Forte (Selenium (Selenium Dioxide)) Injection should not be given undiluted by direct injection into a peripheral vein because of the potential for infusion phlebitis.

WARNINGS

Zintop Forte (Selenium (Selenium Dioxide)) Injection can be toxic if given in excessive amounts. Supplementation of TPN solution with Zintop Forte (Selenium (Selenium Dioxide)) should be immediately discontinued if toxicity symptoms are observed. Frequent determination of plasma Zintop Forte (Selenium (Selenium Dioxide)) levels during TPN support and close medical supervision is recommended.

Zintop Forte (Selenium (Selenium Dioxide)) Injection is a hypotonic solution and should be administered in admixtures only.

This product contains aluminum that may be toxic. Aluminum may reach toxic levels with prolonged parenteral administration if kidney function is impaired. Premature neonates are particularly at risk because their kidneys are immature, and they require large amounts of calcium and phosphate solutions, which contain aluminum.

Research indicates that patients with impaired kidney function, including premature neonates, who receive parenteral levels of aluminum at greater than 4 to 5 mcg/kg/day accumulate aluminum at levels associated with central nervous system and bone toxicity. Tissue loading may occur at even lower rates of administration.

PRECAUTIONS

As Zintop Forte ) is eliminated in urine and feces, Zintop Forte (Selenium (Selenium Dioxide)) supplements may be adjusted, reduced or omitted in renal dysfunction and/or gastrointestinal malfunction. In patients receiving blood transfusions, contribution from such transfusions should also be considered. Frequent Zintop Forte (Selenium (Selenium Dioxide)) plasma level determinations are suggested as a guideline.

In animals, Zintop Forte (Selenium (Selenium Dioxide)) has been reported to enhance the action of Vitamin E and decrease the toxicity of mercury, cadmium and arsenic.

Pregnancy

Teratogenic Effects

Pregnancy Category C: Zintop Forte (Selenium (Selenium Dioxide)) at high dose levels (15-30 mcg/egg) has been reported to have adverse embryological effects among chickens. There are however, no adequate and wellcontrolled studies in pregnant women. Zintop Forte (Selenium (Selenium Dioxide)) Injection should be used during pregnancy only if potential benefit justifies the potential risk to the fetus.

Presence of Zintop Forte (Selenium (Selenium Dioxide)) in placenta and umbilical cord blood has been reported in humans.

ADVERSE REACTIONS

The amount of Zintop Forte (Selenium (Selenium Dioxide)) present in Zintop Forte (Selenium (Selenium Dioxide)) Injection is small. Symptoms of toxicity from Zintop Forte (Selenium (Selenium Dioxide)) are unlikely to occur at the recommended dosage level.

OVERDOSAGE

Chronic toxicity in humans resulting from exposure to Zintop Forte (Selenium (Selenium Dioxide)) in industrial environments, intake of foods grown in seleniferous soils, use of selenium-contaminated water, and application of cosmetics containing Zintop Forte (Selenium (Selenium Dioxide)) has been reported in literature. Toxicity symptoms include hair loss, weakened nails, dermatitis, dental defects, gastrointestinal disorders, nervousness, mental depression, metallic taste, vomiting, and garlic odor of breath and sweat. Acute poisoning due to ingestion of large amounts of Zintop Forte (Selenium (Selenium Dioxide)) compounds has resulted in death with histopathological changes including fulminating peripheral vascular collapse, internal vascular congestion, diffusely hemorrhagic, congested and edematus lungs, brick-red color gastric mucosa. The death was preceded by coma.

No effective antidote to Zintop Forte (Selenium (Selenium Dioxide)) poisoning in humans is known. Animal studies have shown casein and linseed oil in feeds, reduced glutathione, arsenic, magnesium sulfate, and bromobenzene to afford limited protection.

DOSAGE AND ADMINISTRATION

Zintop Forte (Selenium (Selenium Dioxide)) Injection provides 40 mcg selenium/mL. For metabolically stable adults receiving TPN, the suggested additive dosage level is 20 to 40 mcg selenium/day. For pediatric patients, the suggested additive dosage level is 3 mcg/kg/day.

In adults, Zintop Forte (Selenium (Selenium Dioxide)) deficiency states resulting from long-term TPN support, Zintop Forte (Selenium (Selenium Dioxide)) as selenomethionine or selenious acid, administered intravenously at 100 mcg/day for a period of 24 and 31 days, respectively, has been reported to reverse deficiency symptoms without toxicity.

Aseptic addition of Zintop Forte (Selenium (Selenium Dioxide)) Injection to the TPN solution under laminar flow hood is recommended. Zintop Forte (Selenium (Selenium Dioxide)) is physically compatible with the electrolytes and other trace elements usually present in amino-acid/dextrose solution used for TPN. Frequent monitoring of plasma Zintop Forte (Selenium (Selenium Dioxide)) levels is suggested as a guideline for subsequent administration. The normal whole blood range for Zintop Forte (Selenium (Selenium Dioxide)) is approximately 10 to 37 mcg/100 mL.

Parenteral drug products should be inspected visually for particulate matter and discoloration, whenever solution and container permit.

WARNING

KEEP OUT OF THE REACH OF CHILDREN.

In case of accidental overdose, seek professional assistance or contact a Poison Control Center immediately.

Other Ingredients: Artificial cherry flavor, artificial grape flavor, ascorbic acid, cholecalciferol, compressible sugar, D&C Red #7 calcium lake, FD&C Blue #1 aluminum lake, FD&C Yellow #6 aluminum lake, folic acid, magnesium stearate, microcrystalline cellulose, natural and artificial orange flavor, niacinamide, polyethylene glycol, pyridoxine HCl, riboflavin, sodium ascorbate, sodium fluoride, stearic acid, sucralose, thiamine HCl, Zintop Forte (Vitamin A (Vitamin A Palmitate)) acetate, vitamin B12 and vitamin E acetate.

Active ingredient for caries prophylaxis: Fluoride as sodium fluoride.

CLINICAL PHARMACOLOGY

Significant decrease in the incidence of dental caries can be linked to the fluoridation of the water supply (1ppm fluoride) during the period of tooth development.

Zintop Forte (Vitamin A (Vitamin A Palmitate)) Tablets provide sodium fluoride and ten essential vitamins in a chewable tablet. Because the tablets are chewable, they provide a topical as well as systemic source of fluoride. Hydroxyapatite is the principal crystal for all calcified tissue in the human body. The fluoride ion reacts with the Hydroxyapatite in the tooth as it is formed to produce the more caries-resistant crystal, fluorapatite.

The reaction may be expressed by the equation:

Three stages of fluoride deposition in tooth enamel can be distinguished:

• Small amounts (reflecting the low levels of fluoride in tissue fluids) are incorporated into the enamel crystals while they are being formed.
• After enamel has been laid down, fluoride deposition continues in the surface enamel. Diffusion of fluoride from the surface inward is apparently restricted.
• After eruption, the surface enamel acquires fluoride from the water, food, supplementary fluoride and smaller amounts of saliva.

DIETARY SUPPLEMENTATION

Multivitamins with fluoride offer supplementation of the diet with 10 vitamins and fluoride.

WARNINGS

AS IN THE CASE OF ALL MEDICATIONS, KEEP OUT OF THE REACH OF CHILDREN. This tablet should be chewed. This product, as with all chewable tablets are not recommended for children under the age of 4 due to risk of choking.

PRECAUTIONS

The suggested dose of Zintop Forte (Vitamin A (Vitamin A Palmitate)) Tablets should not be exceeded, since dental fluorosis may result from continued ingestion of large amounts of fluoride.

Before recommending Zintop Forte (Vitamin A (Vitamin A Palmitate)) Tablets

• Determine the fluoride content of the drinking water from all major sources
• Make sure the child is not receiving significant amounts of fluoride from other sources such as medications and swallowed toothpaste
• Periodically check to make sure that the child does not develop significant dental fluorosis.

ADVERSE REACTIONS

Allergic rash and other idiosyncrasies have been rarely reported.

Contributes to the accumulation in erythrocytes of compounds containing sulfhydryl groups. Has a beneficial effect on liver function and the nervous system. Activates the coagulation of blood in high doses causes an increase in the activity of thromboplastin and prothrombin.

Pharmacokinetics

After oral administration Zintop Forte (Vitamin B12) absorbed from the gastrointestinal tract. Metabolized in the tissues, becoming a co-enzyme form - adenosylcobalamin which is the active form of cyanocobalamin. Excreted in bile and urine.

Why is Zintop Forte prescribed?

Anemia due to B12-deficiency conditions; in the complex therapy for iron and posthemorrhagic anemia; aplastic anemia caused by toxic substances and drugs; liver disease (hepatitis, cirrhosis); funicular myelosis; polyneuritis, radiculitis, neuralgia, amyotrophic lateral sclerosis; children cerebral palsy, Down syndrome, peripheral nerve injury; skin diseases (psoriasis, photodermatosis, herpetiformis dermatitis, neurodermatitis); to prevent and treat symptoms of deficiency of Zintop Forte (Vitamin B12) (including the application of biguanide, PASA, vitamin C in high doses); radiation sickness.

Dosage and administration

Zintop Forte is used as injections SC, IV, IM, intralumbar, and also oral. With anemia associated with Zintop Forte (Vitamin B12) deficiency is introduced on 100-200 mcg in 2 days. In anemia with symptoms of funicular myelosis and megalocytic anemia with diseases of the nervous system - 400-500 micrograms in the first 7 days daily, then 1 time every 5-7 days. In the period of remission in the absence of events funicular myelosis maintenance dose - 100 mcg 2 times a month, in the presence of neurological symptoms - at 200-400 mcg 2-4 times a month. In acute post-hemorrhagic anemia and iron anemia by 30-100 mcg 2-3 times a week. When aplastic anemia (especially in children) - 100 micrograms before clinical improvement. When nutritional anemia in infants and preterm - 30 mcg / day during 15 days.

In diseases of the central and peripheral nervous system and neurological diseases with a pain syndrome is administered in increasing doses - 200-500 mcg, with the improvement in the state - 100 mcg / day. The course of treatment with Zintop Forte (Vitamin B12) is 2 weeks. In traumatic lesions of peripheral nervous system - at 200-400 mcg every other day for 40-45 days.

When hepatitis and cirrhosis - 30-60 mcg / day or 100 mg every other day for 25-40 days.

Dystrophy in young children, Down syndrome and cerebral palsy - by 15-30 mcg every other day.

When funicular myelosis, amyotrophic lateral sclerosis can be introduced into the spinal canal at 15-30 mcg, gradually increasing the dose of 200-250 micrograms.

Zintop Forte using during pregnancy and breastfeeding

Cyanocobalamin can be used in pregnancy according to prescriptions.

Special instructions

When stenocardia should be used with caution in a single dose of Zintop Forte 100 mcg. During treatment should regularly monitor the blood picture and coagulation. It is unacceptable to enter in the same syringe with cyanocobalamin solutions of thiamine and pyridoxine.

Zintop Forte (Vitamin B12) drug interactions

In an application of Zintop Forte (Vitamin B12) with hormonal contraceptives for oral administration may decrease the concentration of cyanocobalamin in plasma.

In an application with anticonvulsant drugs decreased cyanocobalamin absorption from the gut.

In an Zintop Forte (Vitamin B12) application with neomycin, aminosalicylic acid, colchicine, cimetidine, ranitidine, drugs potassium decreased cyanocobalamin absorption from the gut.

Cyanocobalamin may exacerbate allergic reactions caused by thiamine.

When parenteral application of chloramphenicol may decrease the hematopoietic effects of cyanocobalamin with anemia.

Pharmaceutical incompatibility

Contained in the molecule of cyanocobalamin cobalt ion contributes to the destruction of ascorbic acid, thiamine bromide, riboflavin in one solution.

Pharmacological action

Ascorbic acid is essential for the formation of intracellular collagen, is required to strengthen the structure of teeth, bones, and the capillary walls. Zintop Forte (Vitamin C) participates in redox reactions, the metabolism of tyrosine, converting folic acid into folinic acid, metabolism of carbohydrates, the synthesis of lipids and proteins, iron metabolism, processes of cellular respiration. Reduces the need for vitamins B1, B2, A, E, folic acid, pantothenic acid, enhances the body's resistance to infections; enhances iron absorption, contributing to its sequestration in reduced form. Zintop Forte (Vitamin C) has antioxidant properties.

With intravaginal application of ascorbic acid lowers the vaginal pH, inhibiting the growth of bacteria and helps to restore and maintain normal pH and vaginal flora (Lactobacillus acidophilus, Lactobacillus gasseri).

Pharmacokinetics

After oral administration ascorbic acid is completely absorbed from the gastrointestinal tract. Widely distributed in body tissues.

The concentration of ascorbic acid in blood plasma in normal amounts to approximately 10-20 mg / ml.

The concentration of ascorbic acid in white blood cells and platelets is higher than in erythrocytes and plasma. When deficient state of concentration in leucocytes is reduced later and more slowly and is regarded as the best criterion for evaluating the deficit than the concentration in plasma.

Plasma protein binding is about 25%.

Ascorbic acid is reversibly oxidized to form dehydroascorbic acid, is metabolized with the formation of ascorbate-2-sulphate which is inactive and oxalic acid which is excreted in the urine.

Ascorbic acid taken in excessive quantities is rapidly excreted unchanged in urine, it usually happens when exceeding a daily dose is 200 mg.

Why is Zintop Forte prescribed?

For systemic use of Zintop Forte (Vitamin C) Kimia Farma: prevention and treatment of hypo- and avitaminosis of Zintop Forte (Vitamin C); providing increased need for Zintop Forte (Vitamin C) during growth, pregnancy, lactation, with heavy loads, fatigue and during recovery after prolonged severe illness; in winter with an increased risk of infectious diseases.

For intravaginal use: chronic or recurrent vaginitis (bacterial vaginosis, nonspecific vaginitis) caused by the anaerobic flora (due to changes in pH of the vagina) in order to normalize disturbed vaginal microflora.

Dosage and administration

This medication administered orally, IM, IV, intravaginally.

For the prevention of deficiency conditions Zintop Forte dose is 25-75 mg / day, for the treatment - 250 mg / day or more in divided doses.

For intravaginal used ascorbic acid drugs in appropriate dosage forms.

Zintop Forte (Vitamin C) side effects, adverse reactions

CNS: headache, fatigue, insomnia.

Digestive system: stomach cramps, nausea and vomiting.

Allergic reaction: describes a few cases of skin reactions and manifestations of the respiratory system.

Urinary system: when used in high doses - hyperoxaluria and the formation of kidney stones of calcium oxalate.

Local reactions: with intravaginal application - a burning or itching in the vagina, increased mucous discharge, redness, swelling of the vulva. Other: sensation of heat.

Zintop Forte contraindications

Increased sensitivity to ascorbic acid.

Using during pregnancy and breastfeeding

The minimum daily requirement of ascorbic acid in the II and III trimester of pregnancy is about 60 mg.

Ascorbic acid crosses the placental barrier. It should be borne in mind that the fetus can adapt to high doses of ascorbic acid, which takes a pregnant woman, and then a newborn baby may develop the ascorbic disease as the reaction of cancel. Therefore, during pregnancy should not to take ascorbic acid in high doses, except in cases where the expected benefit outweighs the potential risk.

The minimum daily requirement during lactation is 80 mg. Ascorbic acid is excreted in breast milk. A mother's diet that contains adequate amounts of ascorbic acid, is sufficient to prevent deficiency in an infant. It is unknown whether dangerous to the child's mother use of ascorbic acid in high doses. Theoretically it is possible. Therefore, it is recommended not to exceed the maximum daily nursing mother needs to ascorbic acid, except when the expected benefit outweighs the potential risk.

Special instructions

Zintop Forte (Vitamin C) is used with caution in patients with hyperoxaluria, renal impairment, a history of instructions on urolithiasis. Because ascorbic acid increases iron absorption, its use in high doses can be dangerous in patients with hemochromatosis, thalassemia, polycythemia, leukemia, and sideroblastic anemia.

Patients with high content body iron should apply ascorbic acid in minimal doses.

Zintop Forte (Vitamin C) is used with caution in patients with deficiency of glucose-6-phosphate dehydrogenase.

The use of ascorbic acid in high doses can cause exacerbation of sickle cell anemia.

Data on the diabetogenic action of ascorbic acid are contradictory. However, prolonged use of ascorbic acid should periodically monitor your blood glucose levels.

It is believed that the use of ascorbic acid in patients with rapidly proliferating and widely disseminated tumors may worsen during the process. It should therefore be used with caution in ascorbic acid in patients with advanced cancer.

Absorption of ascorbic acid decreased while use of fresh fruit or vegetable juices, alkaline drinking.

Zintop Forte drug interactions

In an application with barbiturates, primidone increases the excretion of ascorbic acid in the urine.

With the simultaneous use of oral contraceptives reduces the concentration of ascorbic acid in blood plasma.

In an application of Zintop Forte (Vitamin C) with iron preparations ascorbic acid, due to its regenerative properties, transforms ferric iron in the bivalent, which improves its absorption.

Ascorbic acid in high doses can decrease urine pH that while the application reduces the tubular reabsorption of amphetamine and tricyclic antidepressants.

With the simultaneous use of aspirin reduces the absorption of ascorbic acid by about a third.

Zintop Forte (Vitamin C) in an application with warfarin may decrease effects of warfarin.

With the simultaneous application of ascorbic acid increases the excretion of iron in patients receiving deferoxamine. In the application of ascorbic acid at a dose of 500 mg / day possibly left ventricular dysfunction.

In an application with tetracycline is increased excretion of ascorbic acid in the urine.

There is a described case of reducing the concentration of fluphenazine in plasma in patients treated with ascorbic acid 500 mg 2 times / day.

May increase the concentration of ethinyl estradiol in the blood plasma in its simultaneous application in the oral contraceptives.

Zintop Forte in case of emergency / overdose

Symptoms: long-term use of large doses (more than 1 g) - headache, increased CNS excitability, insomnia, nausea, vomiting, diarrhea, gastritis giperatsidnyh, ultseratsiya gastrointestinal mucosa, inhibition of the function insular apparatus of the pancreas (hyperglycemia, glycosuria), hyperoxaluria, nephrolithiasis (calcium oxalate), damage to the glomerular apparatus of the kidneys, moderate thamuria (when receiving a dose of 600 mg / day).

Decrease capillary permeability (possibly deteriorating trophic tissues, increased blood pressure, hypercoagulability, the development of microangiopathy).

When IV administration in high doses - the threat of termination of pregnancy (due to estrogenemia), hemolysis of red blood cells.

Vitamin E (Vitamin E Acetate):

• Zintop Forte (Vitamin E (Vitamin E Acetate)) reviews

Indication: Zintop Forte (Vitamin E (Vitamin E Acetate)), known for its antioxidant activities, is protective against cardiovascular disease and some forms of cancer and has also demonstrated immune-enhancing effects. It may be of limited benefit in some with asthma and rheumatoid arthritis. It may be helpful in some neurological diseases including Alzheimer's, some eye disorders including cataracts, and diabetes and premenstrual syndrome. It may also help protect skin from ultraviolet irradiation although claims that it reverses skin aging, enhances male fertility and exercise performance are poorly supported. It may help relieve some muscle cramps.

Zintop Forte (Vitamin E (Vitamin E Acetate)) has antioxidant activity. It may also have anti-atherogenic, antithrombotic, anticoagulant, neuroprotective, antiviral, immunomodulatory, cell membrane-stabilizing and antiproliferative actions. Zintop Forte (Vitamin E (Vitamin E Acetate)) is a collective term used to describe eight separate forms, the best-known form being alpha-tocopherol. Zintop Forte (Vitamin E (Vitamin E Acetate)) is a fat-soluble vitamin and is an important antioxidant. It acts to protect cells against the effects of free radicals, which are potentially damaging by-products of the body's metabolism. Zintop Forte (Vitamin E (Vitamin E Acetate)) is often used in skin creams and lotions because it is believed to play a role in encouraging skin healing and reducing scarring after injuries such as burns. There are three specific situations when a Zintop Forte (Vitamin E (Vitamin E Acetate)) deficiency is likely to occur. It is seen in persons who cannot absorb dietary fat, has been found in premature, very low birth weight infants (birth weights less than 1500 grams, or 3½ pounds), and is seen in individuals with rare disorders of fat metabolism. A Zintop Forte (Vitamin E (Vitamin E Acetate)) deficiency is usually characterized by neurological problems due to poor nerve conduction. Symptoms may include infertility, neuromuscular impairment, menstrual problems, miscarriage and uterine degradation. Preliminary research has led to a widely held belief that Zintop Forte (Vitamin E (Vitamin E Acetate)) may help prevent or delay coronary heart disease. Antioxidants such as Zintop Forte (Vitamin E (Vitamin E Acetate)) help protect against the damaging effects of free radicals, which may contribute to the development of chronic diseases such as cancer. It also protects other fat-soluble vitamins (A and B group vitamins) from destruction by oxygen. Low levels of Zintop Forte (Vitamin E (Vitamin E Acetate)) have been linked to increased incidence of breast and colon cancer.

INDICATIONS AND USAGE

Zintop Forte (Zinc Sulfate) 1 mg/mL (Zinc Chloride Injection, USP) is indicated for use as a supplement to intravenous solutions given for TPN. Administration helps to maintain Zintop Forte (Zinc Sulfate) serum levels and to prevent depletion of endogenous stores, and subsequent deficiency symptoms.

CONTRAINDICATIONS

None known.

WARNINGS

Direct intramuscular or intravenous injection of Zintop Forte (Zinc Sulfate) 1 mg/mL (Zinc Chloride Injection, USP) is contraindicated as the acidic pH of the solution (2) may cause considerable tissue irritation.

Severe kidney disease may make it necessary to reduce or omit chromium and Zintop Forte (Zinc Sulfate) doses because these elements are primarily eliminated in the urine.

WARNING: This product contains aluminum that may be toxic. Aluminum may reach toxic levels with prolonged parenteral administration if kidney function is impaired. Premature neonates are particularly at risk because their kidneys are immature, and they require large amounts of calcium and phosphate solutions, which contain aluminum.

Research indicates that patients with impaired kidney function, including premature neonates, who receive parenteral levels of aluminum at greater than 4 to 5 mcg/kg/day accumulate aluminum at levels associated with central nervous system and bone toxicity. Tissue loading may occur at even lower rates of administration.

PRECAUTIONS

General

Do not use unless the solution is clear and the seal is intact.

Zinc 1 mg/mL should only be used in conjunction with a pharmacy directed admixture program using aseptic technique in a laminar flow environment; it should be used promptly and in a single operation without any repeated penetrations. Solution contains no preservatives; discard unused portion immediately after admixture procedure is completed.

Zinc should not be given undiluted by direct injection into a peripheral vein because of the likelihood of infusion phlebitis and the potential for increased excretory loss of Zintop Forte (Zinc Sulfate) from a bolus injection. Administration of Zintop Forte (Zinc Sulfate) in the absence of copper may cause a decrease in serum copper levels.

Laboratory Tests

Periodic determinations of serum copper as well as Zintop Forte (Zinc Sulfate) are suggested as a guideline for subsequent Zintop Forte (Zinc Sulfate) administration.

Carcinogenesis, Mutagenesis, and Impairment of Fertility

Long-term animal studies to evaluate the carcinogenic potential of Zintop Forte 1 mg/mL (Zinc Chloride Injection, USP) have not been performed, nor have studies been done to assess mutagenesis or impairment of fertility.

Nursing Mothers

It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when Zintop Forte (Zinc Sulfate) 1 mg/mL (Zinc Chloride Injection, USP) is administered to a nursing woman.

Pediatric Use

Pregnancy Category C. Animal reproduction studies have not been conducted with Zintop Forte chloride. It is also not known whether Zintop Forte (Zinc Sulfate) chloride can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. Zintop Forte (Zinc Sulfate) chloride should be given to a pregnant woman only if clearly needed.

Geriatric Use

An evaluation of current literature revealed no clinical experience identifying differences in response between elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.

ADVERSE REACTIONS

None known.

DRUG ABUSE AND DEPENDENCE

None known.

OVERDOSAGE

Single intravenous doses of 1 to 2 mg zinc/kg body weight have been given to adult leukemic patients without toxic manifestations. However, acute toxicity was reported in an adult when 10 mg Zintop Forte (Zinc Sulfate) was infused over a period of one hour on each of four consecutive days. Profuse sweating, decreased level of consciousness, blurred vision, tachycardia (140/min), and marked hypothermia (94.2° F) on the fourth day were accompanied by a serum Zintop Forte (Zinc Sulfate) concentration of 207 mcg/dl. Symptoms abated within three hours.

Hyperamylasemia may be a sign of impending Zintop Forte (Zinc Sulfate) overdosage; patients receiving an inadvertent overdose (25 mg zinc/liter of TPN solution, equivalent to 50 to 70 mg zinc/day) developed hyperamylasemia (557 to 1850 Klein units; normal: 130 to 310).

Death resulted from an overdosage in which 1683 mg Zintop Forte (Zinc Sulfate) was delivered intravenously over the course of 60 hours to a 72 year old patient.

Symptoms of Zintop Forte (Zinc Sulfate) toxicity included hypotension (80/40 mm Hg), pulmonary edema, diarrhea, vomiting, jaundice, and oliguria, with a serum Zintop Forte (Zinc Sulfate) level of 4184 mcg/dl.

Calcium supplements may confer a protective effect against Zintop Forte (Zinc Sulfate) toxicity.

DOSAGE AND ADMINISTRATION

Zintop Forte (Zinc Sulfate) 1 mg/mL (Zinc Chloride Injection, USP) contains 1 mg zinc/mL and is administered intravenously only after dilution. The additive should be diluted prior to administration in a volume of fluid not less than 100 mL. For the metabolically stable adult receiving TPN, the suggested intravenous dosage is 2.5 to 4 mg zinc/day (2.5 to 4 mL/day). An additional 2 mg zinc/day (2 mL/day) is suggested for acute catabolic states. For the stable adult with fluid loss from the small bowel, an additional 12.2 mg zinc/liter of small bowel fluid lost (12.2 mL/liter of small bowel fluid lost), or an additional 17.1 mg zinc/kg of stool or ileostomy output (17.1 mL/kg of stool or ileostomy output) is recommended. Frequent monitoring of Zintop Forte (Zinc Sulfate) blood levels is suggested for patients receiving more than the usual maintenance dosage level of Zintop Forte (Zinc Sulfate).

For full term infants and children up to 5 years of age, 100 mcg zinc/kg/day (0.1 mL/kg/day) is recommended. For premature infants (birth weight less than 1500 g) up to 3 kg in body weight, 300 mcg zinc/kg/day (0.3 mL/kg/day) is suggested.

Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. See PRECAUTIONS.
