The active ingredient of Navispare brand is amiloride. Amiloride is a potassium-sparing diuretic (water pill) that prevents your body from absorbing too much salt and keeps your potassium levels from getting too low. Each tablet for oral administration contains 5 mg of Amiloride HCI, calculated on the anhydrous basis. Each tablet contains the following inactive ingredients: corn starch, crospovidone, lactose, magnesium stearate, microcrystalline cellulose and povidone. Amiloride HCl is not an aldosterone antagonist and its effects are seen even in the absence of aldosterone. Amiloride exerts its potassium sparing effect through the inhibition of sodium reabsorption at the distal convoluted tubule, cortical collecting tubule and collecting duct; this decreases the net negative potential of the tubular lumen and reduces both potassium and hydrogen secretion and their subsequent excretion. This mechanism accounts in large part for the potassium sparing action of Amiloride. Amiloride usually begins to act within 2 hours after an oral dose. Its effect on electrolyte excretion reaches a peak between 6 and 10 hours and lasts about 24 hours. Peak plasma levels are obtained in 3 to 4 hours and the plasma half-life varies from 6 to 9 hours. Effects on electrolytes increase with single doses of Amiloride HCl up to approximately 15 mg. Amiloride HCl is not metabolized by the liver but is excreted unchanged by the kidneys. About 50 percent of a 20 mg dose of Amiloride HCl is excreted in the urine and 40 percent in the stool within 72 hours. Amiloride has little effect on glomerular filtration rate or renal blood flow. Because Amiloride HCl is not metabolized by the liver, drug accumulation is not anticipated in patients with hepatic dysfunction, but accumulation can occur if the hepatorenal syndrome develops. a. help restore normal serum potassium levels in patients who develop hypokalemia on the kaliuretic diuretic b. prevent development of hypokalemia in patients who would be exposed to particular risk if hypokalemia were to develop, e.g., digitalized patients or patients with significant cardiac arrhythmias. The use of potassium-conserving agents is often unnecessary in patients receiving diuretics for uncomplicated essential hypertension when such patients have a normal diet. Amiloride HCl tablets have little additive diuretic or antihypertensive effect when added to a thiazide diuretic. Amiloride HCl tablets should rarely be used alone. It has weak (compared with thiazides) diuretic and antihypertensive effects. Used as single agents, potassium sparing diuretics, including Amiloride HCl tablets, result in an increased risk of hyperkalemia (approximately 10% with Amiloride). Amiloride HCl tablets should be used alone only when persistent hypokalemia has been documented and only with careful titration of the dose and close monitoring of serum electrolytes. Amiloride HCl tablets should not be used in the presence of elevated serum potassium levels (greater than 5.5 mEq per liter). Antikaliuretic Therapy or Potassium Supplementation Amiloride HCl tablets should not be given to patients receiving other potassium-conserving agents, such as spironolactone or triamterene. Potassium supplementation in the form of medication, potassium-containing salt substitutes or a potassium-rich diet should not be used with Amiloride HCl tablets except in severe and/or refractory cases of hypokalemia. Such concomitant therapy can be associated with rapid increases in serum potassium levels. If potassium supplementation is used, careful monitoring of the serum potassium level is necessary. Impaired Renal Function Anuria, acute or chronic renal insufficiency, and evidence of diabetic nephropathy are contraindications to the use of Amiloride HCl tablets. Patients with evidence of renal functional impairment (blood urea nitrogen [BUN] levels over 30 mg per 100 mL or serum creatinine levels over 1.5 mg per 100 mL) or diabetes mellitus should not receive the drug without careful, frequent and continuing monitoring of serum electrolytes, creatinine, and BUN levels. Potassium retention associated with the use of an antikaliuretic agent is accentuated in the presence of renal impairment and may result in the rapid development of hyperkalemia. Hypersensitivity Amiloride HCl tablets are contraindicated in patients who are hypersensitive to this product. WARNINGS
