Also known as Aldactone
Spironolactone (INN, BAN, USAN) , commonly referred to simply as "spiro", and marketed primarily under the brand name Aldactone in most countries, is a synthetic, steroidal antimineralocorticoid agent with additional antiandrogen and weak progestogen properties, as well as some indirect estrogen and glucocorticoid effects, which is used primarily as a diuretic and antihypertensive, but also for the purpose of reducing elevated or unwanted androgen activity in the body. It acts predominantly as a competitive antagonist of the aldosterone (or mineralocorticoid) receptor, and belongs to a class of pharmaceutical drugs known as potassium-sparing diuretics.Source: Wikipedia
