Aldactone Tablet Uses

Aldactone Tablet contains Spironolactone. Aldactone uses:

Aldactone Tablet is indicated in Congestive heart failure, Hepatic cirrhosis with ascites and oedema, Nephrotic syndrome, Primary hyperaldosteronism, Essential hypertension, For the treatment of patients with hypokalemia

Aldactone Tablet is a long-acting aldosterone antagonist. Aldactone Tablet is a specific pharmacologic antagonist of aldosterone, acting primarily through competitive binding of receptors at the aldosterone dependent sodium-potassium exchange site in the distal convoluted renal tubule. Aldactone Tablet causes increased amounts of sodium and water to be excreted, while potassium and magnesium is retained.

Aldactone Tablet Doses

Aldactone Tablet contains Spironolactone 25 mg. Aldactone doses:

Edema in adults (congestive heart failure, hepatic cirrhosis, or nephrotic syndrome): An initial daily dosage of 100 mg of Aldactone Tablet administered in either single or divided doses is recommended, but may range from 25 to 200 mg daily. Combined therapy with other diuretics is indicated when more rapid diuresis is desired.

Primary hyperaldosteronism: After the diagnosis of hyperaldosteronism has been established, Aldactone Tablet may be administered in doses of 100 to 400 mg daily in preparation for surgery. For patients who are considered unsuitable for surgery, Aldactone Tablet may be employed for long-term maintenance therapy at the lowest effective dosage determined for the individual patient.

Essential hypertension: For adults, an initial daily dosage of 50 to 100 mg of Aldactone Tablet administered in either single or divided doses is recommended.

Hypokalemia: Aldactone Tablet in a dosage ranging from 25 mg to 100 mg daily is useful in treating a diuretic-induced hypokalemia.

Introduction

Aldactone Tablet is a specific pharmacologic antagonist of aldosterone, acting primarily through competitive binding of receptors at the aldosterone-dependent sodium-potassium exchange site in the distal convoluted renal tubule. Aldactone Tablet causes increased amounts of sodium and water to be excreted, while potassium is retained. Aldactone Tablet acts both as a diuretic and as an antihypertensive drug by this mechanism. It may be given alone or with other diuretic agents which act more proximally in the renal tubule. Aldosterone interacts with a cytoplasmic mineralocorticoid receptor to enhance the expression of the Na+ K+ ATPase and the Na+ channel involved in a Na+ K+transport in the distal tubule . Aldactone Tablet bind to this mineralcorticoid receptor, blocking the actions of aldosterone on gene expression. Aldosterone is a hormone; its primary function is to retain sodium and excrete potassium in the kidneys.

Aldactone Precaution

All patients receiving diuretic therapy should be observed for evidence of fluid or electrolyte imbalance. Hyperkalemia may occur in patients with impaired renal function or excessive potassium intake and can cause cardiac irregularities, which may be fatal.

Interaction

ACE inhibitors: Concomitant administration of ACE inhibitors with potassium-sparing diuretics has been associated with severe hyperkalemia.

Alcohol, barbiturates, or narcotics: Potentiation of orthostatic hypotension may occur.

Corticosteroids, ACTH: Intensified electrolyte depletion, particularly hypokalemia, may occur.

Lithium: Lithium generally should not be given with diuretics. Diuretic agents reduce the renal clearance of lithium and add a high risk of lithium toxicity.

Digoxin: Aldactone Tablet has been shown to increase the half-life of digoxin.

Pregnancy Lactation use

Pregnancy: Aldactone Tablet should not be used during pregnancy

Lactation: Canrenone, an active metabolite of Aldactone Tablet, appears in breast milk. If use of the drug is deemed essential an alternative method of infant feeding should be instituted.

Contraindication
