AI summarySynthesized from FDA + DailyMed + ClinicalTrials.gov data
ALDACTONE (spironolactone) is an oral aldosterone antagonist approved in 1960 for managing fluid retention and electrolyte imbalances in conditions like heart failure, cirrhosis, and hypertension. It works by blocking aldosterone receptors in the collecting duct, reducing sodium reabsorption and potassium excretion. The drug is used across multiple indications as both monotherapy and adjunctive therapy.
