From Wiki (because it was fast ) Novo-spiroton or spironolactone:
".......It is a synthetic 17-lactone drug that is a renal competitive aldosterone antagonist in a class of pharmaceuticals called potassium-sparing diuretics, used primarily to treat heart failure, ascites in patients with liver disease, low-renin hypertension, hypokalemia, secondary hyperaldosteronism (such as occurs with hepatic cirrhosis), and Conn's syndrome (primary hyperaldosteronism).
On its own, spironolactone is only a weak diuretic because its effects target the distal nephron (collecting tubule), where urine volume can only be slightly modified; but it can be combined with other diuretics to increase efficacy. About one person in one hundred with hypertension has elevated levels of aldosterone; in these persons, the antihypertensive effect of spironolactone may exceed that of complex combined regimens of other antihypertensives.
Due to its antiandrogen effect, it can also be used to treat hirsutism, and is a common component in hormone therapy for male-to-female transsexual and transgender people. It is also used for treating hair loss and acne in women, and can be used as a topical medication for treatment of male baldness. It is commonly used to treat symptoms of polycystic ovary syndrome (PCOS) such as excess facial hair and acne.
It can also cause gynecomastia (big man boobies) in males and should never be given with potassium supplementation for fear of the development of hyperkalemia....."
That about sums it up
