Spironolactone: A Re-Examination

Abstract

A review of the aldosterone antagonist spironolactone is presented. It is effective both as monotherapy and in combination with other hypotensive agents in the control of both essential and hyperaldosterone-induced hypertension. It is useful as a diuretic in conditions such as cirrhosis and congestive heart failure, and is most commonly employed because of its potassium- and magnesium-sparing qualities. Spironolactone also has been used as an antiandrogenic agent in managing hirsutism. Its adverse effect profile, considered somewhat prohibitive in the past, is generally not significant when reasonably low doses (<150 mg/d) are used.
