Eplerenone

Eplerenone (INN) ( /ɛpˈlɛrənoʊn/) is an aldosterone antagonist used as an adjunct in the management of chronic heart failure. It is similar to the diuretic spironolactone, though it is much more selective for the mineralocorticoid receptor in comparison (i.e., does not possess any antiandrogen, progestogen, or estrogenic effects), and is specifically marketed for reducing cardiovascular risk in patients following myocardial infarction. It is marketed by Pfizer under the trade name Inspra. Eplerenone is a potassium-sparing diuretic, meaning that it helps the body get rid of water but still keep potassium.
