Canrenone (INN, USAN) (brand names Contaren, Luvion, Phanurane, Spiroletan) is a steroidal antimineralocorticoid and weak antiandrogen and progestogen[1][2] related to spironolactone which is used as a diuretic in Europe.[3][4]

Carenone is a major active metabolite of spironolactone, canrenoic acid, and potassium canrenoate, and is believed to be partially or largely responsible for their effects.[5]

Canrenone is more potent as an antimineralocorticoid relative to spironolactone, but is considerably less potent and effective as an antiandrogen.[6][7] Similarly to spironolactone, canrenone inhibits steroidogenic enzymes such as 11β-hydroxylase, cholesterol side-chain cleavage enzyme, 17α-hydroxylase, and 21-hydroxylase, but once again, is comparatively more potent in doing so.[8]

Canrenone has been found to be effective in the treatment of hirsutism in women.[9]
