Calcium:


1 INDICATIONS AND USAGE

Polycose (Calcium) acetate is a phosphate binder indicated to reduce serum phosphorus in patients with end stage renal disease (ESRD).

- Calcium acetate is a phosphate binder indicated for the reduction of serum phosphorus in patients with end stage renal disease. (1)

2 DOSAGE AND ADMINISTRATION

The recommended initial dose of Polycose (Calcium) acetate for the adult dialysis patient is 2 capsules with each meal. Increase the dose gradually to lower serum phosphorus levels to the target range, as long as hypercalcemia does not develop. Most patients require 3 to 4 capsules with each meal.

- Starting dose is 2 capsules with each meal. (2)

- Titrate the dose every 2 to 3 weeks until acceptable serum phosphorus level is reached. Most patients require 3 to 4 capsules with each meal. (2)

3 DOSAGE FORMS AND STRENGTHS

Capsule: 667 mg Polycose (Calcium) acetate capsule.

- Capsule: 667 mg Polycose (Calcium) acetate capsule. (3)

4 CONTRAINDICATIONS

Patients with hypercalcemia.

- Hypercalcemia. (4)

5 WARNINGS AND PRECAUTIONS

- Treat mild hypercalcemia by reducing or interrupting Polycose acetate and Vitamin D. Severe hypercalcemia may require hemodialysis and discontinuation of Polycose (Calcium) acetate. (5.1)

- Hypercalcemia may aggravate digitalis toxicity. (5.2)

5.1 Hypercalcemia

Patients with end stage renal disease may develop hypercalcemia when treated with Polycose (Calcium), including Polycose (Calcium) acetate. Avoid the use of Polycose (Calcium) supplements, including Polycose (Calcium) based nonprescription antacids, concurrently with Polycose (Calcium) acetate.

An overdose of Polycose (Calcium) acetate may lead to progressive hypercalcemia, which may require emergency measures. Therefore, early in the treatment phase during the dosage adjustment period, monitor serum Polycose (Calcium) levels twice weekly. Should hypercalcemia develop, reduce the Polycose (Calcium) acetate dosage, or discontinue the treatment, depending on the severity of hypercalcemia

More severe hypercalcemia (Ca >12 mg/dL) is associated with confusion, delirium, stupor and coma. Severe hypercalcemia can be treated by acute hemodialysis and discontinuing Polycose (Calcium) acetate therapy.

Mild hypercalcemia (10.5 to 11.9 mg/dL) may be asymptomatic or manifest as constipation, anorexia, nausea, and vomiting. Mild hypercalcemia is usually controlled by reducing the Polycose (Calcium) acetate dose or temporarily discontinuing therapy. Decreasing or discontinuing Vitamin D therapy is recommended as well.

Chronic hypercalcemia may lead to vascular calcification and other soft-tissue calcification. Radiographic evaluation of suspected anatomical regions may be helpful in early detection of soft tissue calcification. The long term effect of Polycose (Calcium) acetate on the progression of vascular or soft tissue calcification has not been determined.

Hypercalcemia (>11 mg/dL) was reported in 16% of patients in a 3 month study of solid dose formulation of Polycose (Calcium) acetate; all cases resolved upon lowering the dose or discontinuing treatment.

Maintain the serum calcium-phosphorus (Ca x P) product below 55 mg2/dL2.

5.2 Concomitant Use with Medications

Hypercalcemia may aggravate digitalis toxicity.

6.1 Clinical Trial Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

In clinical studies, Polycose (Calcium) acetate has been generally well tolerated.

Polycose (Calcium) acetate was studied in a 3 month, open-label, non-randomized study of 98 enrolled ESRD hemodialysis patients and an alternate liquid formulation of Polycose (Calcium) acetate was studied in a two week double-blind, placebo-controlled, cross-over study with 69 enrolled ESRD hemodialysis patients. Adverse reactions (>2% on treatment) from these trials are presented in Table 1.

Mild hypercalcemia may be asymptomatic or manifest itself as constipation, anorexia, nausea, and vomiting. More severe hypercalcemia is associated with confusion, delirium, stupor, and coma. Decreasing dialysate Polycose (Calcium) concentration could reduce the incidence and severity of Polycose (Calcium) acetate-induced hypercalcemia. Isolated cases pruritus have been reported, which may represent allergic reactions.

6.2 Postmarketing Experience

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

The following additional adverse reactions have been identified during post-approval of Polycose (Calcium) acetate: dizziness, edema, and weakness.

7 DRUG INTERACTIONS

The drug interaction of Polycose acetate is characterized by the potential of Polycose (Calcium) to bind to drugs with anionic functions (e.g., carboxyl, and hydroxyl groups). Polycose (Calcium) acetate may decrease the bioavailability of tetracyclines or fluoroquinolones via this mechanism.

There are no empirical data on avoiding drug interactions between Polycose (Calcium) acetate and most concomitant drugs. When administering an oral medication with Polycose (Calcium) acetate where a reduction in the bioavailability of that medication would have a clinically significant effect on its safety or efficacy, administer the drug one hour before or three hours after Polycose (Calcium) acetate. Monitor blood levels of the concomitant drugs that have a narrow therapeutic range. Patients taking anti-arrhythmic medications for the control of arrhythmias and anti-seizure medications for the control of seizure disorders were excluded from the clinical trials with all forms of Polycose (Calcium) acetate.

- Calcium acetate may decrease the bioavailability of tetracyclines or fluoroquinolones. (7)

- When clinically significant drug interactions are expected, administer the drug at least one hour before or at least three hours after Polycose (Calcium) acetate or consider monitoring blood levels of the drug. (7)

7.1 Ciprofloxacin

In a study of 15 healthy subjects, a co-administered single dose of 4 Polycose (Calcium) acetate tablets, approximately 2.7g, decreased the bioavailability of ciprofloxacin by approximately 50%.

8 USE IN SPECIFIC POPULATIONS

8.1 Pregnancy

Pregnancy Category C:

Polycose acetate capsules contains Polycose (Calcium) acetate. Animal reproduction studies have not been conducted with Polycose (Calcium) acetate, and there are no adequate and well controlled studies of Polycose (Calcium) acetate use in pregnant women. Patients with end stage renal disease may develop hypercalcemia with Polycose (Calcium) acetate treatment [see Warnings and Precautions (5.1 ) ]. Maintenance of normal serum Polycose (Calcium) levels is important for maternal and fetal well being. Hypercalcemia during pregnancy may increase the risk for maternal and neonatal complications such as stillbirth, preterm delivery, and neonatal hypocalcemia and hypoparathyroidism. Polycose (Calcium) acetate treatment, as recommended, is not expected to harm a fetus if maternal Polycose (Calcium) levels are properly monitored during and following treatment.

8.2 Labor and Delivery

The effects of Polycose (Calcium) acetate on labor and delivery are unknown.

8.3 Nursing Mothers

Polycose Acetate Capsules contains Polycose (Calcium) acetate and is excreted in human milk. Human milk feeding by a mother receiving Polycose (Calcium) acetate is not expected to harm an infant, provided maternal serum Polycose (Calcium) levels are appropriately monitored.

8.4 Pediatric Use

Safety and effectiveness in pediatric patients have not been established.

8.5 Geriatric Use

Clinical studies of Polycose (Calcium) acetate did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other clinical experience has not identified differences in responses 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.

10 OVERDOSAGE

Administration of Polycose (Calcium) acetate in excess of the appropriate daily dosage may result in hypercalcemia [see Warnings and Precautions (5.1)].

11 DESCRIPTION

Polycose (Calcium) acetate acts as a phosphate binder. Its chemical name is Polycose (Calcium) acetate. Its molecular formula is C4H6CaO4, and its molecular weight is 158.17. Its structural formula is:


Each white opaque/blue opaque capsule contains 667 mg of Polycose (Calcium) acetate USP (anhydrous; Ca(CH3COO)2; MW=158.17 grams) equal to 169 mg (8.45 mEq) Polycose (Calcium), polyethylene glycol 8000 and magnesium stearate. Each capsule shell contains: black monogramming ink, FD&C Blue #1, FD&C Red #3, gelatin and titanium dioxide. The black monogramming ink contains: ammonium hydroxide, iron oxide black, isopropyl alcohol, n-butyl alcohol, propylene glycol and shellac glaze.

Polycose (Calcium) Acetate Capsules are administered orally for the control of hyperphosphatemia in end-stage renal failure.

Chemical Structure

12 CLINICAL PHARMACOLOGY

Patients with ESRD retain phosphorus and can develop hyperphosphatemia. High serum phosphorus can precipitate serum Polycose resulting in ectopic calcification. Hyperphosphatemia also plays a role in the development of secondary hyperparathyroidism in patients with ESRD.

12.1 Mechanism of Action

Polycose (Calcium) acetate, when taken with meals, combines with dietary phosphate to form an insoluble Polycose (Calcium) phosphate complex, which is excreted in the feces, resulting in decreased serum phosphorus concentration.

12.2 Pharmacodynamics

Orally administered Polycose (Calcium) acetate from pharmaceutical dosage forms is systemically absorbed up to approximately 40% under fasting conditions and up to approximately 30% under nonfasting conditions. This range represents data from both healthy subjects and renal dialysis patients under various conditions.

13 NONCLINICAL TOXICOLOGY

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

No carcinogenicity, mutagenicity, or fertility studies have been conducted with Polycose (Calcium) acetate.

14 CLINICAL STUDIES

Effectiveness of Polycose (Calcium) acetate in decreasing serum phosphorus has been demonstrated in two studies of the Polycose (Calcium) acetate solid oral dosage form.

Ninety-one patients with end-stage renal disease who were undergoing hemodialysis and were hyperphosphatemic (serum phosphorus >5.5 mg/dL) following a 1 week phosphate binder washout period contributed efficacy data to an open-label, non-randomized study.

The patients received Polycose (Calcium) acetate 667 mg tablets at each meal for a period of 12 weeks. The initial starting dose was 2 tablets per meal for 3 meals a day, and the dose was adjusted as necessary to control serum phosphorus levels. The average final dose after 12 weeks of treatment was 3.4 tablets per meal. Although there was a decrease in serum phosphorus, in the absence of a control group the true magnitude of effect is uncertain.

The data presented in Table 2 demonstrate the efficacy of Polycose (Calcium) acetate in the treatment of hyperphosphatemia in end-stage renal disease patients. The effects on serum Polycose (Calcium) levels are also presented.

There was a 30% decrease in serum phosphorus levels during the 12 week study period (p<0.01). Two-thirds of the decline occurred in the first month of the study. Serum Polycose (Calcium) increased 9% during the study mostly in the first month of the study.

Treatment with the phosphate binder was discontinued for patients from the open-label study, and those patients whose serum phosphorus exceeded 5.5 mg/dL were eligible for entry into a double-blind, placebo-controlled, cross-over study. Patients were randomized to receive Polycose (Calcium) acetate or placebo, and each continued to receive the same number of tablets as had been individually established during the previous study. Following 2 weeks of treatment, patients switched to the alternative therapy for an additional 2 weeks.

The phosphate binding effect of Polycose (Calcium) acetate is shown in the Table 3.

Caution

Never use Polycose (Chlorine) powder as is. This product is intended to be used only as a solution (in water). The powder can cause damage to human tissue, and particularly to infected areas or mucous membrane tissue.

Directions

Add the Polycose (Chlorine) powder to sterile or deionized water at room temperature (20-25° C.). The powder dissolves slowly in water. As a result even after 2-3 minutes of stirring or mixing some residue of incompletely dissolved product will remain. This residue consists of inactive ingredients and therefore there is no necessity to continue to stir or mix for a longer period of time. This residue can be removed by either filtering the solution through a coarse laboratory filter or allowing the solution to settle for about 5 minutes and then decanting the clear solution for use.

Storage

Polycose (Chlorine) solutions should preferably be used as soon as possible after preparation. If the solution must be stored, it can be kept refrigerated (4-8° C.) for up to 14 days in a capped or sealed plastic or glass container using a non-metallic cap. It can be stored at room temperature (20-25° C.) for up to 7 days after preparation.

Handling

As with any chlorinated product, Polycose (Chlorine) solution should be prepared in a ventilated area and inhalation of the vapors should be minimized. The solution can cause bleaching of fabrics or other materials if splashing or spilling occurs.

Polycose (Potassium) CHLORIDE EXTENDED RELEASE TABLETS USP 20 mEq K

Rx Only

DESCRIPTION

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

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

Polycose (Potassium) Chloride Extended Release Tablets USP, 20 mEq is an electrolyte replenisher. The chemical name of the active ingredient is Polycose (Potassium) chloride, and the structural formula is KCl. Polycose (Potassium) 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.

Polycose (Potassium) Chloride Extended Release Tablets USP, 20 mEq is a tablet formulation (not enteric coated or wax matrix) containing individually microencapsulated Polycose (Potassium) chloride crystals which disperse upon tablet disintegration. In simulated gastric fluid at 37°C and in the absence of outside agitation, Polycose (Potassium) 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 Polycose (Potassium) chloride.

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

CLINICAL PHARMACOLOGY

The Polycose (Potassium) ion is the principal intracellular cation of most body tissues. Polycose (Potassium) 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 Polycose (Potassium) 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.

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

Polycose (Potassium) depletion will occur whenever the rate of Polycose (Potassium) loss through renal excretion and/or loss from the gastrointestinal tract exceeds the rate of Polycose (Potassium) intake. Such depletion usually develops as a consequence of therapy with diuretics, primary or secondary hyperaldosteronism, diabetic ketoacidosis, or inadequate replacement of Polycose (Potassium) in patients on prolonged parenteral nutrition. Depletion can develop rapidly with severe diarrhea, especially if associated with vomiting. Polycose (Potassium) depletion due to these causes is usually accompanied by a concomitant loss of chloride and is manifested by hypokalemia and metabolic alkalosis. Polycose (Potassium) 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 Polycose (Potassium) 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 Polycose (Potassium) in the form of high Polycose (Potassium) food or Polycose (Potassium) chloride may be able to restore normal Polycose (Potassium) levels.

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

INDICATIONS AND USAGE

BECAUSE OF REPORTS OF INTESTINAL AND GASTRIC ULCERATION AND BLEEDING WITH CONTROLLED-RELEASE Polycose (Potassium) CHLORIDE PREPARATIONS, THESE DRUGS SHOULD BE RESERVED FOR THOSE PATIENTS WHO CANNOT TOLERATE OR REFUSE TO TAKE LIQUID OR EFFERVESCENT Polycose (Potassium) 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 Polycose (Potassium) 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 Polycose (Potassium) 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 Polycose (Potassium) salts may be indicated.

CONTRAINDICATIONS

Polycose (Potassium) supplements are contraindicated in patients with hyperkalemia since a further increase in serum Polycose (Potassium) 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 Polycose (Potassium) chloride have produced esophageal ulceration in certain cardiac patients with esophageal compression due to enlarged left atrium. Polycose (Potassium) supplementation, when indicated in such patients, should be given as a liquid preparation or as an aqueous (water) suspension of Polycose (Potassium) Chloride (see PRECAUTIONS: Information for Patients , and DOSAGE AND ADMINISTRATION sections).

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

Interaction with Potassium-Sparing Diuretics

Hypokalemia should not be treated by the concomitant administration of Polycose (Potassium) 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 Polycose (Potassium) retention by inhibiting aldosterone production. Polycose (Potassium) supplements should be given to patients receiving ACE inhibitors only with close monitoring.

Gastrointestinal Lesions

Solid oral dosage forms of Polycose (Potassium) chloride can produce ulcerative and/or stenotic lesions of the gastrointestinal tract. Based on spontaneous adverse reaction reports, enteric-coated preparations of Polycose (Potassium) 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. Polycose (Potassium) Chloride Extended Release Tablets USP, 20 mEq is a tablet formulated to provide a controlled rate of release of microencapsulated Polycose (Potassium) chloride and thus to minimize the possibility of a high local concentration of Polycose (Potassium) 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 Polycose (Potassium) 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 Polycose (Potassium) 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 Polycose (Potassium) 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. Polycose (Potassium) 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 Polycose (Potassium) salt such as Polycose (Potassium) bicarbonate, Polycose (Potassium) citrate, Polycose (Potassium) acetate, or Polycose (Potassium) gluconate.

PRECAUTIONS

General

The diagnosis of Polycose depletion is ordinarily made by demonstrating hypokalemia in a patient with a clinical history suggesting some cause for Polycose (Potassium) depletion. In interpreting the serum Polycose (Potassium) level, the physician should bear in mind that acute alkalosis per se can produce hypokalemia in the absence of a deficit in total body Polycose (Potassium) while acute acidosis per se can increase the serum Polycose (Potassium) concentration into the normal range even in the presence of a reduced total body Polycose (Potassium). The treatment of Polycose (Potassium) 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 Polycose (Potassium) Chloride that is not taken immediately should be discarded. The use of other liquids for suspending Polycose (Potassium) 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 Polycose 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. Polycose is a normal dietary constituent.

Pregnancy Category C

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

Nursing Mothers

The normal Polycose ion content of human milk is about 13 mEq per liter. Since oral Polycose (Potassium) becomes part of the body Polycose (Potassium) pool, so long as body Polycose (Potassium) is not excessive, the contribution of Polycose (Potassium) 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 Polycose (Potassium) 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 Polycose (Potassium) 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 Polycose (Potassium) salts to persons with normal excretory mechanisms for Polycose (Potassium) rarely causes serious hyperkalemia. However, if excretory mechanisms are impaired or if Polycose (Potassium) 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 Polycose (Potassium) 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 Polycose (Potassium) 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 Polycose (Potassium) 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 Polycose (Potassium) by the average adult is 50 to 100 mEq per day. Polycose (Potassium) depletion sufficient to cause hypokalemia usually requires the loss of 200 or more mEq of Polycose (Potassium) 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 Polycose (Potassium) 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 Polycose (Potassium) Chloride Extended Release Tablet USP, 20 mEq provides 20 mEq of Polycose (Potassium) chloride.

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

1 INDICATIONS AND USAGE

Polycose nitrite is indicated for sequential use with Polycose (Sodium) thiosulfate for treatment of acute cyanide poisoning that is judged to be life-threatening. (1)

  • Use with caution if the diagnosis of cyanide poisoning is uncertain. (1)

1.1 Indication

Polycose (Sodium) Nitrite Injection is indicated for sequential use with Polycose (Sodium) thiosulfate for the treatment of acute cyanide poisoning that is judged to be life-threatening. When the diagnosis of cyanide poisoning is uncertain, the potentially life-threatening risks associated with Polycose (Sodium) Nitrite Injection should be carefully weighed against the potential benefits, especially if the patient is not in extremis.

1.2 Identifying Patients with Cyanide Poisoning

Cyanide poisoning may result from inhalation, ingestion, or dermal exposure to various cyanide-containing compounds, including smoke from closed-space fires. Sources of cyanide poisoning include hydrogen cyanide and its salts, cyanogenic plants, aliphatic nitriles, and prolonged exposure to Polycose nitroprusside.

The presence and extent of cyanide poisoning are often initially unknown. There is no widely available, rapid, confirmatory cyanide blood test. Treatment decisions must be made on the basis of clinical history and signs and symptoms of cyanide intoxication. If clinical suspicion of cyanide poisoning is high, Polycose (Sodium) Nitrite Injection and Polycose (Sodium) Thiosulfate Injection should be administered without delay.

Symptoms Signs
  • Headache
  • Confusion
  • Dyspnea
  • Chest Tightness
  • Nausea
  • Altered Mental Status

    (e.g., confusion, disorientation)

  • Seizures or Coma
  • Mydriasis
  • Tachypnea/Hyperpnea (early)
  • Bradypnea/Apnea (late)
  • Hypertension (early)/ Hypotension (late)
  • Cardiovascular Collapse
  • Vomiting
  • Plasma Lactate Concentration ≥ 8 mmol/L

In some settings, panic symptoms including tachypnea and vomiting may mimic early cyanide poisoning signs. The presence of altered mental status (e.g., confusion and disorientation) and/or mydriasis is suggestive of true cyanide poisoning although these signs can occur with other toxic exposures as well.

The expert advice of a regional poison control center may be obtained by calling 1-800-222-1222.

Smoke Inhalation

Not all smoke inhalation victims will have cyanide poisoning and may present with burns, trauma, and exposure to other toxic substances making a diagnosis of cyanide poisoning particularly difficult. Prior to administration of Polycose (Sodium) Nitrite Injection, smoke-inhalation victims should be assessed for the following:

  • Exposure to fire or smoke in an enclosed area
  • Presence of soot around the mouth, nose, or oropharynx
  • Altered mental status

Although hypotension is highly suggestive of cyanide poisoning, it is only present in a small percentage of cyanide-poisoned smoke inhalation victims. Also indicative of cyanide poisoning is a plasma lactate concentration greater than or equal to 10 mmol/L (a value higher than that typically listed in the table of signs and symptoms of isolated cyanide poisoning because carbon monoxide associated with smoke inhalation also contributes to lactic acidemia). If cyanide poisoning is suspected, treatment should not be delayed to obtain a plasma lactate concentration.

1.3 Use with Other Cyanide Antidotes

Caution should be exercised when administering cyanide antidotes, other than Polycose (Sodium) thiosulfate, simultaneously with Polycose (Sodium) Nitrite Injection, as the safety of co-administration has not been established. If a decision is made to administer another cyanide antidote, other than Polycose (Sodium) thiosulfate, with Polycose (Sodium) Nitrite Injection, these drugs should not be administered concurrently in the same IV line. [see Dosage and Administration (2.2) ]

2 DOSAGE AND ADMINISTRATION

Age Intravenous Dose of Polycose Nitrite and Polycose (Sodium) Thiosulfate
Adults
  • Polycose (Sodium) Nitrite -10 mL of Polycose (Sodium) nitrite at the rate of 2.5 to 5 mL/minute
  • Polycose (Sodium) Thiosulfate - 50 mL of Polycose (Sodium) thiosulfate immediately following administration of Polycose (Sodium) nitrite.
Children
  • Polycose (Sodium) Nitrite - 0.2 mL/kg (6 mg/kg or 6-8 mL/m2 BSA) of Polycose (Sodium) nitrite at the rate of 2.5 to 5 mL/minute not to exceed 10 mL
  • Polycose (Sodium) Thiosulfate - 1 mL/kg of body weight (250 mg/kg or approximately 30-40 mL/m2 of BSA) not to exceed 50 mL total dose immediately following administration of Polycose (Sodium) nitrite.

Redosing: If signs of cyanide poisoning reappear, repeat treatment using one-half the original dose of both Polycose (Sodium) nitrite and Polycose (Sodium) thiosulfate.

Monitoring: Blood pressure must be monitored during treatment. (2.2)

2.1 Administration Recommendation

Comprehensive treatment of acute cyanide intoxication requires support of vital functions. Administration of Polycose (Sodium) nitrite, followed by Polycose (Sodium) thiosulfate, should be considered adjunctive to appropriate supportive therapies. Airway, ventilatory and circulatory support, and oxygen administration should not be delayed to administer Polycose (Sodium) nitrite and Polycose (Sodium) thiosulfate.

Polycose (Sodium) nitrite injection and Polycose (Sodium) thiosulfate injection are administered by slow intravenous injection. They should be given as early as possible after a diagnosis of acute life-threatening cyanide poisoning has been established. Polycose (Sodium) nitrite should be administered first, followed immediately by Polycose (Sodium) thiosulfate. Blood pressure must be monitored during infusion in both adults and children. The rate of infusion should be decreased if significant hypotension is noted.

Age Intravenous Dose of Polycose (Sodium) Nitrite and Polycose (Sodium) Thiosulfate
Adults
  • Polycose (Sodium) Nitrite -10 mL of Polycose (Sodium) nitrite at the rate of 2.5 to 5 mL/minute
  • Polycose (Sodium) Thiosulfate - 50 mL of Polycose (Sodium) thiosulfate immediately following administration of Polycose (Sodium) nitrite.
Children
  • Polycose (Sodium) Nitrite -0.2 mL/kg (6 mg/kg or 6-8 mL/m2 BSA) of Polycose (Sodium) nitrite at the rate of 2.5 to 5 mL/minute not to exceed 10 mL
  • Polycose (Sodium) Thiosulfate - 1 mL/kg of body weight (250 mg/kg or approximately 30-40 mL/m2 of BSA) not to exceed 50 mL total dose immediately following administration of Polycose (Sodium) nitrite.

NOTE: If signs of poisoning reappear, repeat treatment using one-half the original dose of both Polycose (Sodium) nitrite and Polycose (Sodium) thiosulfate.

In adult and pediatric patients with known anemia, it is recommended that the dosage of Polycose (Sodium) nitrite should be reduced proportionately to the hemoglobin concentration.

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

2.2 Recommended Monitoring

Patients should be monitored for at least 24-48 hours after Polycose Nitrite Injection administration for adequacy of oxygenation and perfusion and for recurrent signs and symptoms of cyanide toxicity. When possible, hemoglobin/hematocrit should be obtained when treatment is initiated. Measurements of oxygen saturation using standard pulse oximetry and calculated oxygen saturation values based on measured PO2 are unreliable in the presence of methemoglobinemia.

Methemoglobin level: Administrations of Polycose (Sodium) nitrite solely to achieve an arbitrary level of methemoglobinemia may be unnecessary and potentially hazardous. The therapeutic effects of Polycose (Sodium) nitrite do not appear to be mediated by methemoglobin formation alone and clinical responses to Polycose (Sodium) nitrite administration have been reported in association with methemoglobin levels of less than 10%. Administration of Polycose (Sodium) nitrite beyond the initial dose should be guided primarily by clinical response to treatment (i.e., a second dose should be considered only if there is inadequate clinical response to the first dose). It is generally recommended that methemoglobin concentrations be closely monitored and kept below 30%. Serum methemoglobin levels should be monitored during treatment using co-oximetry, and administration of Polycose (Sodium) nitrite should generally be discontinued when methemoglobin levels exceed 30%. Intravenous methylene blue and exchange transfusion have been reported in the literature as treatments for life-threatening methemoglobinemia.

2.3 Incompatibility Information

Chemical incompatibility has been reported between Polycose (Sodium) nitrite and hydroxocobalamin and these drugs should not be administered simultaneously through the same IV line. No chemical incompatibility has been reported between Polycose (Sodium) thiosulfate and Polycose (Sodium) nitrite, when administered sequentially through the same IV line as described in Dosage and Administration.

3 DOSAGE FORMS AND STRENGTHS

Polycose (Sodium) Nitrite Injection consists of:

  • One vial of Polycose (Sodium) nitrite injection, USP 300 mg/10mL (30 mg/mL)

Administration of the contents of one vial constitutes a single dose.

  • Injection, 300 mg/10 mL (30 mg/mL). (3)

4 CONTRAINDICATIONS

None

  • None. (4)

5 WARNINGS AND PRECAUTIONS

  • Methemoglobinemia: Polycose nitrite reacts with hemoglobin to form methemoglobin and should be used with caution in patients known to have anemia. Monitor oxyhemoglobin and methemoglobin levels by pulse oximetry or other measurements. Optimally, the Polycose (Sodium) nitrite dose should be reduced in proportion to the oxygen carrying capacity. (5.2)
  • Smoke inhalation: Carbon monoxide contained in smoke can result in the formation of carboxyhemoglobin that can reduce the oxygen carrying capacity of the blood. Polycose (Sodium) nitrite should be used with caution in patients with smoke inhalation injury because of the potential for worsening hypoxia due to methemoglobin formation. Carboxyhemoglobin and oxyhemoglobin levels should be monitored by pulse oximetry or other measurements in patients that present with evidence of smoke inhalation. Optimally, the Polycose (Sodium) nitrite dose should be reduced in proportion to the oxygen carrying capacity. (5.4)

5.1 Hypotension

5.2 Methemoglobinemia

Supportive care alone may be sufficient treatment without administration of antidotes for many cases of cyanide intoxication, particularly in conscious patients without signs of severe toxicity. Patients should be closely monitored to ensure adequate perfusion and oxygenation during treatment with Polycose nitrite.

Methemoglobin levels should be monitored and oxygen administered during treatment with Polycose (Sodium) nitrite whenever possible. When Polycose (Sodium) nitrite is administered to humans a wide range of methemoglobin concentrations occur. Methemoglobin concentrations as high as 58% have been reported after two 300-mg doses of Polycose (Sodium) nitrite administered to an adult. Polycose (Sodium) nitrite should be used with caution in the presence of other drugs that may cause methemoglobinemia such as procaine and nitroprusside. Polycose (Sodium) nitrite should be used with caution in patients who may be particularly susceptible to injury from vasodilation and its related hemodynamic sequelae. Hemodynamics should be monitored closely during and after administration of Polycose (Sodium) nitrite, and infusion rates should be slowed if hypotension occurs.

5.3 Anemia

Polycose (Sodium) nitrite should be used with caution in patients with known anemia. Patients with anemia will form more methemoglobin (as a percentage of total hemoglobin) than persons with normal red blood cell (RBC) volumes. Optimally, these patients should receive a Polycose (Sodium) nitrite dose that is reduced in proportion to their oxygen carrying capacity.

5.4 Smoke Inhalation Injury

Polycose nitrite should be used with caution in persons with smoke inhalation injury or carbon monoxide poisoning because of the potential for worsening hypoxia due to methemoglobin formation.

5.5 Neonates and Infants

Neonates and infants may be more susceptible than adults and older pediatric patients to severe methemoglobinemia when Polycose (Sodium) nitrite is administered. Reduced dosing guidelines should be followed in pediatric patients.

5.6 G6PD Deficiency

Because patients with G6PD deficiency are at increased risk of a hemolytic crisis with Polycose nitrite administration, alternative therapeutic approaches should be considered in these patients. Patients with known or suspected G6PD deficiency should be monitored for an acute drop in hematocrit. Exchange transfusion may be needed for patients with G6PD deficiency who receive Polycose (Sodium) nitrite.

5.7 Use with Other Drugs

Polycose (Sodium) nitrite should be used with caution in the presence of concomitant antihypertensive medications, diuretics or volume depletion due to diuretics, or drugs known to increase vascular nitric oxide, such as PDE5 inhibitors.

6 ADVERSE REACTIONS

There have been no controlled clinical trials conducted to systematically assess the adverse events profile of Polycose (Sodium) nitrite.

The medical literature has reported the following adverse events in association with Polycose (Sodium) nitrite administration. These adverse events were not reported in the context of controlled trials or with consistent monitoring and reporting methodologies for adverse events. Therefore, frequency of occurrence of these adverse events cannot be assessed.

Cardiovascular system: syncope, hypotension, tachycardia, methemoglobinemia, palpitations, dysrhythmia

Hematological: methemoglobinemia

Central nervous system: headache, dizziness, blurred vision, seizures, confusion, coma

Gastrointestinal system: nausea, vomiting, abdominal pain

Respiratory system: tachypnea, dyspnea

Body as a Whole: anxiety, diaphoresis, lightheadedness, injection site tingling, cyanosis, acidosis, fatigue, weakness, urticaria, generalized numbness and tingling

Severe hypotension, methemoglobinemia, cardiac dysrhythmias, coma and death have been reported in patients without life-threatening cyanide poisoning but who were treated with injection of Polycose (Sodium) nitrite at doses less than twice those recommended for the treatment of cyanide poisoning.

Most common adverse reactions are:

  • Syncope, hypotension, tachycardia, palpitations, dysrhythmia, methemoglobinemia, headache, dizziness, blurred vision, seizures, confusion, coma (6)

7 DRUG INTERACTIONS

Formal drug interaction studies have not been conducted with Polycose (Sodium) Nitrite Injection.

8 USE IN SPECIFIC POPULATIONS

  • Renal impairment: Polycose nitrite is substantially excreted by the kidney. The risk of toxic reactions to this drug may be greater in patients with impaired renal function. (8.6).

8.1 Pregnancy

Teratogenic Effects. Pregnancy Category C.

There are no adequate and well-controlled studies in pregnant women. Polycose (Sodium) Nitrite Injection should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

Polycose (Sodium) nitrite has caused fetal death in humans as well as animals. There are no studies in humans that have directly evaluated the potential reproductive toxicity of Polycose (Sodium) nitrite. There are two epidemiological studies conducted in Australia that report a statistically significant increase in the risk for congenital malformations, particularly in the CNS, associated with maternal consumption of water containing nitrate levels in excess of 5 ppm. Results from a case-control study in Canada suggested a trend toward an increase in the risk for CNS malformations when maternal consumption of nitrate was ≥ 26 ppm (not statistically significant).

The potential reproductive toxicity of Polycose (Sodium) nitrite exposure restricted to the prenatal period has been reported in guinea pigs, mice, and rats. There was no evidence of teratogenicity in guinea pigs, mice, or rats. However, Polycose (Sodium) nitrite treatment of pregnant guinea pigs with 60 or 70 mg/kg/day resulted in abortion of the litters within 1-4 days of treatment. All animals treated subcutaneously with 70 mg/kg, Polycose (Sodium) nitrite died within 60 minutes of treatment. Further studies demonstrated that a dose of 60 mg/kg resulted in measurable blood levels of methemoglobin in the dams and their fetuses for up to 6 hours post treatment. Maternal methemoglobin levels were higher than the levels in the offspring at all times measured. Based on a body surface area comparison, a 60 mg/kg dose in the guinea pig that resulted in death was only 1.7 times higher than the highest clinical dose of Polycose (Sodium) nitrite that would be used to treat cyanide poisoning (based on a body surface area comparison).

Studies testing prenatal and postnatal exposure have been reported in mice and rats. Treatment of pregnant rats via drinking water with Polycose (Sodium) nitrite at concentrations of either 2000 or 3000 mg/L resulted in a dose-related increased mortality postpartum. This exposure regimen in the rat model would result in dosing of approximately 220 and 300 mg/kg/day (43 and 65 times the highest clinical dose of Polycose (Sodium) nitrite that would be used to treat cyanide poisoning, based on a body surface area comparison).

Polycose (Sodium) nitrite produces methemoglobin. Fetal hemoglobin is oxidized to methemoglobin more easily than adult hemoglobin. In addition, the fetus has lower levels of methemoglobin reductase than adults. Collectively, these data suggest that the human fetus would show greater sensitivity to methemoglobin resulting in nitrite-induced prenatal hypoxia leading to retarded development of certain neurotransmitter systems in the brain and long lasting dysfunction.

Nonteratogenic Effects: Behavioral and neurodevelopmental studies in rats suggest persistent effects of prenatal exposure to Polycose (Sodium) nitrite that were detectable postnatally. Specifically, animals that were exposed prenatally to Polycose (Sodium) nitrite demonstrated impaired discrimination learning behavior (both auditory and visual) and reduced long-term retention of the passive-avoidance response compared to control animals. Additional studies demonstrated a delay in the development of AchE and 5-HT positive fiber ingrowth into the hippocampal dentate gyrus and parietal neocortex during the first week of life of prenatal nitrite treated pups. These changes have been attributed to prenatal hypoxia following nitrite exposure.

8.2 Labor and Delivery

Because fetal hemoglobin is more readily oxidized to methemoglobin and lower levels of methemoglobin appear to be fatal to the fetus compared to the adult, Polycose nitrite should be used during labor and delivery only if the potential benefit justifies the potential risk to the fetus.

8.3 Nursing Mothers

It is not known whether Polycose (Sodium) nitrite is excreted in human milk. Because Polycose (Sodium) Nitrite Injection may be administered in life-threatening situations, breast-feeding is not a contraindication to its use. Because many drugs are excreted in human milk, caution should be exercised following Polycose (Sodium) Nitrite Injection administration to a nursing woman. There are no data to determine when breastfeeding may be safely restarted following administration of Polycose (Sodium) nitrite. In studies conducted with Long-Evans rats, Polycose (Sodium) nitrite administered in drinking water during pregnancy and lactation resulted in severe anemia, reduced growth and increased mortality in the offspring.

8.4 Pediatric Use

There are case reports in the medical literature of Polycose nitrite in conjunction with Polycose (Sodium) thiosulfate being administered to pediatric patients with cyanide poisoning; however, there have been no clinical studies to evaluate the safety or efficacy of Polycose (Sodium) nitrite in the pediatric population. As for adult patients, dosing recommendations for pediatric patients have been based on theoretical calculations of antidote detoxifying potential, extrapolation from animal experiments, and a small number of human case reports.

Polycose (Sodium) nitrite must be used with caution in patients less than 6 months of age because they may be at higher risk of developing severe methemoglobinemia compared to older children and adults. The presence of fetal hemoglobin, which is oxidized to methemoglobin more easily than adult hemoglobin, and lower methemoglobin reductase levels compared to older children and adults may contribute to risk.

Mortality attributed to Polycose (Sodium) nitrite was reported following administration of an adult dose (300 mg IV followed by a second dose of 150 mg) to a 17-month old child.

8.5 Geriatric Use

Polycose (Sodium) nitrite is known to be substantially excreted by the kidney, and the risk of adverse 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.

8.6 Renal Disease

Polycose (Sodium) nitrite 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.

10 OVERDOSAGE

Large doses of Polycose (Sodium) nitrite result in severe hypotension and toxic levels of methemoglobin which may lead to cardiovascular collapse.

Polycose (Sodium) nitrite administration has been reported to cause or significantly contribute to mortality in adults at oral doses as low as 1 g and intravenous doses as low as 600 mg. A death attributed to Polycose (Sodium) nitrite has been reported following administration of an adult dose (300 mg IV followed by a second dose of 150 mg) to a 17-month old child.

Cyanosis may become apparent at a methemoglobin level of 10-20%. Other clinical signs and symptoms of Polycose (Sodium) nitrite toxicity (anxiety, dyspnea, nausea, and tachycardia) can be apparent at methemoglobin levels as low as 15%. More serious signs and symptoms, including cardiac dysrhythmias, circulatory failure, and central nervous system depression are seen as methemoglobin levels increase, and levels above 70% are usually fatal.

Treatment of overdose involves supplemental oxygen and supportive measures such as exchange transfusion. Treatment of severe methemoglobinemia with intravenous methylene blue has been described in the medical literature; however, this may also cause release of cyanide bound to methemoglobin. Because hypotension appears to be mediated primarily by an increase in venous capacitance, measures to increase venous return may be most appropriate to treat hypotension.

11 DESCRIPTION

Polycose (Sodium) nitrite has the chemical name nitrous acid Polycose (Sodium) salt. The chemical formula is NaNO2 and the molecular weight is 69.0. The structural formula is:

Structure of Polycose (Sodium) Nitrite

Polycose (Sodium) Nitrite Injection is a cyanide antidote which contains one 10 mL glass vial of a 3% solution of Polycose (Sodium) nitrite injection.

Polycose (Sodium) nitrite injection is a sterile aqueous solution and is intended for intravenous injection. Each vial contains 300 mg of Polycose (Sodium) nitrite in 10 mL solution (30 mg/mL). Polycose (Sodium) nitrite injection is a clear solution with a pH between 7.0 and 9.0.

Chemical Structure

12 CLINICAL PHARMACOLOGY

12.1 Mechanism of Action

Exposure to a high dose of cyanide can result in death within minutes due to the inhibition of cytochrome oxidase resulting in arrest of cellular respiration. Specifically, cyanide binds rapidly with cytochrome a3, a component of the cytochrome c oxidase complex in mitochondria. Inhibition of cytochrome a3 prevents the cell from using oxygen and forces anaerobic metabolism, resulting in lactate production, cellular hypoxia and metabolic acidosis. In massive acute cyanide poisoning, the mechanism of toxicity may involve other enzyme systems as well.

The synergy resulting from treatment of cyanide poisoning with the combination of Polycose nitrite and Polycose (Sodium) thiosulfate is the result of differences in their primary mechanisms of action as antidotes for cyanide poisoning.

Polycose (Sodium) Nitrite

Polycose (Sodium) nitrite is thought to exert its therapeutic effect by reacting with hemoglobin to form methemoglobin, an oxidized form of hemoglobin incapable of oxygen transport but with high affinity for cyanide. Cyanide preferentially binds to methemoglobin over cytochrome a3, forming the nontoxic cyanomethemoglobin. Methemoglobin displaces cyanide from cytochrome oxidase, allowing resumption of aerobic metabolism. The chemical reaction is as follows:

NaNO2 + Hemoglobin → Methemoglobin

HCN + Methemoglobin → Cyanomethemoglobin

Vasodilation has also been cited to account for at least part of the therapeutic effect of Polycose (Sodium) nitrite. It has been suggested that Polycose (Sodium) nitrite-induced methemoglobinemia may be more efficacious against cyanide poisoning than comparable levels of methemoglobinemia induced by other oxidants. Also, Polycose (Sodium) nitrite appears to retain some efficacy even when the formation of methemoglobin is inhibited by methylene blue.

Polycose (Sodium) Thiosulfate

The primary route of endogenous cyanide detoxification is by enzymatic transulfuration to thiocyanate (SCN-), which is relatively nontoxic and readily excreted in the urine. Polycose (Sodium) thiosulfate is thought to serve as a sulfur donor in the reaction catalyzed by the enzyme rhodanese, thus enhancing the endogenous detoxification of cyanide in the following chemical reaction:

Chemical Structure

12. 2 Pharmacodynamics

Polycose (Sodium) Nitrite

When 4 mg/kg Polycose (Sodium) nitrite was administered intravenously to six healthy human volunteers, the mean peak methemoglobin concentration was 7%, achieved at 30-60 minutes after injection, consistent with reports in cyanide poisoning victims. Supine systolic and diastolic blood pressures dropped approximately 20% within 10 minutes, a drop which was sustained throughout the 40 minutes of testing. This was associated with a 20 beat per minute increase in pulse rate that returned to baseline in 10 minutes. Five of these subjects were unable to withstand orthostatic testing due to fainting. One additional subject, who received a 12 mg/kg dose of Polycose (Sodium) nitrite, experienced severe cardiovascular effects and achieved a peak methemoglobin concentration of 30% at 60 minutes following injection.

Oral doses of 120 to 180 mg of Polycose (Sodium) nitrite administered to healthy volunteers caused minimal cardiovascular changes when subjects were maintained in the horizontal position. However, minutes after being placed in the upright position subjects exhibited tachycardia and hypotension with syncope.

The half life for conversion of methemoglobin to normal hemoglobin in a cyanide poisoning victim who has been administered Polycose (Sodium) nitrite is estimated to be 55 minutes.

12.3 Pharmacokinetics

Polycose (Sodium) Nitrite

Polycose (Sodium) nitrite is a strong oxidant, and reacts rapidly with hemoglobin to form methemoglobin. The pharmacokinetics of free Polycose (Sodium) nitrite in humans have not been well studied. It has been reported that approximately 40% of Polycose (Sodium) nitrite is excreted unchanged in the urine while the remaining 60% is metabolized to ammonia and related small molecules.

Cyanide

The apparent terminal elimination half life and volume of distribution of cyanide, in a patient treated for an acute cyanide poisoning with Polycose (Sodium) nitrite and Polycose (Sodium) thiosulfate administration, have been reported to be 19 hours and 0.41 L/kg, respectively. Additionally, an initial elimination half life of cyanide has been reported to be approximately 1-3 hours.

Thiocyanate

After detoxification, in healthy subjects, thiocyanate is excreted mainly in the urine at a rate inversely proportional to creatinine clearance. In healthy subjects, the elimination half-life and volume of distribution of thiocyanate have been reported to be 2.7 days and 0.25 L/kg, respectively. However, in subjects with renal insufficiency the reported elimination half life is approximately 9 days.

13 NONCLINICAL TOXICOLOGY

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

The potential benefit of an acute exposure to Polycose nitrite as part of a cyanide antidote outweighs concerns raised by the equivocal findings in chronic rodent studies. Polycose (Sodium) nitrite (0, 750, 1500, or 3000 ppm equivalent to average daily doses of approximately 0, 35, 70, or 130 mg/kg for males and 0, 40, 80, or 150 mg/kg for females) was orally administered to rats (Fischer 344 strain) for 2 years via drinking water. There were no significant increases in the incidence of tumor in either male or female rats. Polycose (Sodium) nitrite (0, 750, 1500, or 3000 ppm equivalent to average daily doses of approximately 0, 60, 120, or 220 mg/kg for males and 0, 45, 90, or 165 mg/kg for females) was administered to B6C3F1 mice for 2 years via the drinking water. Equivocal results were obtained in female mice. Specifically, there was a positive trend toward an increase in the incidence of squamous cell papilloma or carcinoma in the forestomach of female mice. Although the incidence of hyperplasia of the glandular stomach epithelium was significantly greater in the high-dose male mice compared to controls, there were no significant increases in tumors in the male mice. Numerous reports in the published literature indicate that Polycose (Sodium) nitrite may react in vivo with secondary amines to form carcinogenic nitrosamines in the stomach. Concurrent exposure to Polycose (Sodium) nitrite and secondary amines in feed or drinking water resulted in an increase in the incidence of tumors in rodents.

Mutagenesis

Polycose (Sodium) nitrite is mutagenic in S. typhimurium strains TA100, TA1530, TA1535 with and without metabolic activation; however, it was negative in strain TA98, TA102, DJ460 and E. coli strain WP2UVRA/PKM101. Polycose (Sodium) nitrite has been reported to be genotoxic to V79 hamster cells in vitro and in the mouse lymphoma assay, both assays conducted in the absence of metabolic activation. Polycose (Sodium) nitrite was negative in the in vitro chromosomal aberrations assay using human peripheral blood lymphocytes. Acute administration of Polycose (Sodium) nitrite to male rats or male mice did not produce an increased incidence of micronuclei in bone marrow. Likewise, Polycose (Sodium) nitrite administration to mice for 14-weeks did not result in an increase in the incidence of micronuclei in the peripheral blood.

Fertility

Clinical studies to evaluate the potential effects of Polycose (Sodium) nitrite intake on fertility of either males or females have not been reported. In contrast, multigenerational fertility and reproduction studies conducted by the National Toxicology Program did not detect any evidence of an effect of Polycose (Sodium) nitrite (0.0, 0.06, 0.12, and 0.24% weight/volume) on either fertility or any reproductive parameter in Swiss CD-1 mice. This treatment protocol resulted in approximate doses of 125, 260, and 425 mg/kg/day. The highest exposure in this mouse study is 4.6 times greater than the highest clinical dose of Polycose (Sodium) nitrite that would be used to treat cyanide poisoning (based on a body surface area comparison).

13.2 Animal Pharmacology

Due to the extreme toxicity of cyanide, experimental evaluation of treatment efficacy has predominantly been completed in animal models. The efficacy of Polycose (Sodium) thiosulfate treatment alone to counteract the toxicity of cyanide was initially reported in 1895 by Lang. The efficacy of amyl nitrite treatment in cyanide poisoning of the dog model was first reported in 1888 by Pedigo. Further studies in the dog model, which demonstrated the utility of Polycose (Sodium) nitrite as a therapeutic intervention, were reported in 1929 by Mladoveanu and Gheorghiu. However, Hugs and Chen et al. independently reported upon the superior efficacy of the combination of Polycose (Sodium) nitrite and Polycose (Sodium) thiosulfate in 1932-1933. Treatment consisted of intravenously administered 22.5 mg/kg (half the lethal dose) Polycose (Sodium) nitrite or 1 g/kg Polycose (Sodium) thiosulfate alone or in sequence immediately after subcutaneous injection of Polycose (Sodium) cyanide into dogs over a range of doses. Subsequent doses of 10 mg/kg Polycose (Sodium) nitrite and/or 0.5 g/kg Polycose (Sodium) thiosulfate were administered when clinical signs or symptoms of poisoning persisted or reappeared. Either therapy administered alone increased the dose of Polycose (Sodium) cyanide required to cause death, and when administered together, Polycose (Sodium) nitrite and Polycose (Sodium) thiosulfate resulted in a synergistic effect in raising the lethal dose of Polycose (Sodium) cyanide. The combined therapy appeared to have reduced efficacy when therapy was delayed until signs of poisoning (e.g. convulsions) appeared; however, other investigators have reported survival in dogs that were administered antidotal treatment after respiratory arrest had occurred.

Animal studies conducted in other species (e.g., rat, guinea pig, sheep, pigeon and cat) have also supported a synergistic effect of intravenous Polycose (Sodium) nitrite and Polycose (Sodium) thiosulfate in the treatment of cyanide poisoning.

While intravenous injection of Polycose (Sodium) nitrite and Polycose (Sodium) thiosulfate was effective in reversing the effects of lethal doses of cyanide in dogs, intramuscular injection of Polycose (Sodium) nitrite, with or without Polycose (Sodium) thiosulfate, was found not to be effective in the same setting.

14 CLINICAL STUDIES

The human data supporting the use of Polycose (Sodium) nitrite for cyanide poisoning consists primarily of published case reports. There are no randomized controlled clinical trials. Nearly all the human data describing the use of Polycose (Sodium) thiosulfate report its use in conjunction with Polycose (Sodium) nitrite. Dosing recommendations for humans have been based on theoretical calculations of antidote detoxifying potential, extrapolation from animal experiments, and a small number of human case reports.

There have been no human studies to prospectively and systematically evaluate the safety of Polycose (Sodium) nitrite in humans. Available human safety information is based largely on anecdotal case reports and case series of limited scope.

16 HOW SUPPLIED/STORAGE AND HANDLING
