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 Iberin Folico ) 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 Iberin Folico (Iron (Ferrous Sulfate)) 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 Iberin Folico (Iron (Ferrous Sulfate)) therapy and were reported to be intolerant (defined as precluding further use of that Iberin Folico (Iron (Ferrous Sulfate)) product). When these patients were treated with Iberin Folico (Iron (Ferrous Sulfate)) there were no occurrences of adverse reactions that precluded further use of Iberin Folico (Iron (Ferrous Sulfate)) .

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 Iberin Folico (Iron (Ferrous Sulfate)) maintenance treatment with Iberin Folico (Iron (Ferrous Sulfate)) 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 Iberin Folico (Iron (Ferrous Sulfate)) 0.5 mg/kg, 53% (25/47) of the patients receiving Iberin Folico (Iron (Ferrous Sulfate)) 1.0 mg/kg, and 55% (26/47) of the patients receiving Iberin Folico (Iron (Ferrous Sulfate)) 2.0 mg/kg.

A total of 5 (11%) subjects in the Iberin Folico (Iron (Ferrous Sulfate)) 0.5 mg/kg group, 10 (21%) patients in the Iberin Folico (Iron (Ferrous Sulfate)) 1.0 mg/kg group, and 10 (21%) patients in the Iberin Folico (Iron (Ferrous Sulfate)) 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 Iberin Folico (Iron (Ferrous Sulfate)). 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 Iberin Folico (Iron (Ferrous Sulfate)) 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 Iberin Folico (Iron (Ferrous Sulfate)) injection. Reactions have occurred following the first dose or subsequent doses of Iberin Folico (Iron (Ferrous Sulfate)). 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 Iberin Folico (Iron (Ferrous Sulfate)) have not been studied. However, Iberin Folico (Iron (Ferrous Sulfate)) may reduce the absorption of concomitantly administered oral Iberin Folico (Iron (Ferrous Sulfate)) 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, Iberin Folico ) sucrose was administered intravenously to rats and rabbits during the period of organogenesis at doses up to 13 mg/kg/day of elemental Iberin Folico (Iron (Ferrous Sulfate)) (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 Iberin Folico (Iron (Ferrous Sulfate)) sucrose. Because animal reproductive studies are not always predictive of human response, Iberin Folico (Iron (Ferrous Sulfate)) should be used during pregnancy only if clearly needed.

8.3 Nursing Mothers

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

8.4 Pediatric Use

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

Safety and effectiveness of Iberin Folico (Iron (Ferrous Sulfate)) for Iberin Folico (Iron (Ferrous Sulfate)) maintenance treatment in pediatric patients 2 years of age and older with dialysis-dependent or non-dialysis-dependent CKD receiving erythropoietin therapy were studied. Iberin Folico (Iron (Ferrous Sulfate)) 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)]

Iberin Folico (Iron (Ferrous Sulfate)) has not been studied in patients younger than 2 years of age.

In a country where Iberin Folico (Iron (Ferrous Sulfate)) 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 Iberin Folico (Iron (Ferrous Sulfate)), several other medications and erythropoietin. Necrotizing enterocolitis may be a complication of prematurity in very low birth weight infants. No causal relationship to Iberin Folico (Iron (Ferrous Sulfate)) or any other drugs could be established.

8.5 Geriatric Use

Clinical studies of Iberin Folico (Iron (Ferrous Sulfate)) 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 Iberin Folico (Iron (Ferrous Sulfate)), 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 Iberin Folico (Iron (Ferrous Sulfate)) in humans. Excessive dosages of Iberin Folico (Iron (Ferrous Sulfate)) may lead to accumulation of Iberin Folico (Iron (Ferrous Sulfate)) in storage sites potentially leading to hemosiderosis. Do not administer Iberin Folico (Iron (Ferrous Sulfate)) to patients with Iberin Folico (Iron (Ferrous Sulfate)) overload.

Toxicities in single-dose studies in mice and rats, at intravenous Iberin Folico (Iron (Ferrous Sulfate)) 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

12 CLINICAL PHARMACOLOGY

12.1 Mechanism of Action

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

12.2 Pharmacodynamics

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

12.3 Pharmacokinetics

In healthy adults administered intravenous doses of Iberin Folico ), its Iberin Folico (Iron (Ferrous Sulfate)) 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 Iberin Folico (Iron (Ferrous Sulfate)) component appeared to distribute mainly in blood and to some extent in extravascular fluid. A study evaluating Iberin Folico (Iron (Ferrous Sulfate)) containing 100 mg of Iberin Folico (Iron (Ferrous Sulfate)) labeled with ⁵²Fe/⁵⁹Fe in patients with Iberin Folico (Iron (Ferrous Sulfate)) deficiency showed that a significant amount of the administered Iberin Folico (Iron (Ferrous Sulfate)) is distributed to the liver, spleen and bone marrow and that the bone marrow is an irreversible Iberin Folico (Iron (Ferrous Sulfate)) trapping compartment.

Following intravenous administration of Iberin Folico (Iron (Ferrous Sulfate)), Iberin Folico (Iron (Ferrous Sulfate)) sucrose is dissociated into Iberin Folico (Iron (Ferrous Sulfate)) and sucrose. The sucrose component is eliminated mainly by urinary excretion. In a study evaluating a single intravenous dose of Iberin Folico (Iron (Ferrous Sulfate)) containing 1,510 mg of sucrose and 100 mg of Iberin Folico (Iron (Ferrous Sulfate)) 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 Iberin Folico (Iron (Ferrous Sulfate)) 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 Iberin Folico (Iron (Ferrous Sulfate)) sucrose containing 500 to 700 mg of Iberin Folico (Iron (Ferrous Sulfate)) in 26 patients with anemia on erythropoietin therapy (23 female, 3 male; age range 16 to 60), approximately 5% of the Iberin Folico (Iron (Ferrous Sulfate)) was eliminated in urine in 24 h at each dose level. The effects of age and gender on the pharmacokinetics of Iberin Folico (Iron (Ferrous Sulfate)) have not been studied.

Pharmacokinetics in Pediatric Patients

Pharmacokinetics in Pediatric Patients

In a single-dose PK study of Iberin Folico (Iron (Ferrous Sulfate)), patients with NDD-CDK ages 12 to 16 (N=11) received intravenous bolus doses of Iberin Folico (Iron (Ferrous Sulfate)) at 7 mg/kg (maximum 200 mg) administered over 5 minutes. Following single dose Iberin Folico (Iron (Ferrous Sulfate)), the half-life of total serum Iberin Folico (Iron (Ferrous Sulfate)) 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.

Iberin Folico (Iron (Ferrous Sulfate)) is not dialyzable through CA210 (Baxter) High Efficiency or Fresenius F80A High Flux dialysis membranes. In in vitro studies, the amount of Iberin Folico (Iron (Ferrous Sulfate)) 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 Iberin Folico (Iron (Ferrous Sulfate)) sucrose.

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

Iberin Folico (Iron (Ferrous Sulfate)) sucrose at intravenous doses up to 15 mg/kg/day of elemental Iberin Folico (Iron (Ferrous Sulfate)) (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 Iberin Folico ).

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 Iberin Folico (Iron (Ferrous Sulfate)) treatment and 24 in the historical control group) with Iberin Folico (Iron (Ferrous Sulfate)) deficiency anemia. Eligibility criteria for Iberin Folico (Iron (Ferrous Sulfate)) 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.

Iberin Folico (Iron (Ferrous Sulfate)) 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 Iberin Folico (Iron (Ferrous Sulfate)), who were off intravenous Iberin Folico (Iron (Ferrous Sulfate)) 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 Iberin Folico (Iron (Ferrous Sulfate)) 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 Iberin Folico (Iron (Ferrous Sulfate)) in 23 patients with Iberin Folico (Iron (Ferrous Sulfate)) deficiency and HDD-CKD who had been discontinued from Iberin Folico (Iron (Ferrous Sulfate)) 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 Iberin Folico (Iron (Ferrous Sulfate)). Exclusion criteria were similar to those in studies A and B. Iberin Folico (Iron (Ferrous Sulfate)) was administered in doses of 100 mg during sequential dialysis sessions until a pre-determined (calculated) total dose of Iberin Folico (Iron (Ferrous Sulfate)) 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 Iberin Folico (Iron (Ferrous Sulfate)) versus Iberin Folico (Iron (Ferrous Sulfate)) 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 Iberin Folico (Iron (Ferrous Sulfate)) (325 mg ferrous sulfate three times daily for 56 days); or Iberin Folico (Iron (Ferrous Sulfate)) (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 Iberin Folico (Iron (Ferrous Sulfate)) 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 Iberin Folico (Iron (Ferrous Sulfate)) group.

A statistically significantly greater proportion of Iberin Folico (Iron (Ferrous Sulfate)) subjects (35/79; 44.3%) compared to oral Iberin Folico (Iron (Ferrous Sulfate)) 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 Iberin Folico (Iron (Ferrous Sulfate)) to patients with PDD-CKD receiving an erythropoietin alone without Iberin Folico (Iron (Ferrous Sulfate)) 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 Iberin Folico (Iron (Ferrous Sulfate)) or Iberin Folico (Iron (Ferrous Sulfate)) (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 Iberin Folico (Iron (Ferrous Sulfate)) / 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 Iberin Folico (Iron (Ferrous Sulfate)) / 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 Iberin Folico (Iron (Ferrous Sulfate)) / 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: Iberin Folico ) 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 Iberin Folico (Iron (Ferrous Sulfate)) 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 Iberin Folico (Iron (Ferrous Sulfate)) (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 Iberin Folico (Iron (Ferrous Sulfate)) once every other week for 6 doses. Patients with PDD-CKD or NDD-CKD received Iberin Folico (Iron (Ferrous Sulfate)) 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 Iberin Folico (Iron (Ferrous Sulfate)) 0.5 mg/kg, 1.0 mg/kg, and 2.0 mg/kg groups, respectively. A dose-response relationship was not demonstrated.

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. Iberin Folico (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. Iberin Folico (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 Iberin Folico prescribed?

For systemic use of Iberin Folico (Vitamin C) Kimia Farma: prevention and treatment of hypo- and avitaminosis of Iberin Folico (Vitamin C); providing increased need for Iberin Folico (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 Iberin Folico 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.

Iberin Folico (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.

Iberin Folico 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

Iberin Folico (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.

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

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.

Iberin Folico 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 Iberin Folico (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.

Iberin Folico (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.

Iberin Folico 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).
