Eplerenone is available as a 25 mg and 50 mg oral tablet.

Eplerenone is an aldosterone receptor antagonist and is used to treat heart failure after a heart attack and high blood pressure.

Eplerenone is a mineralocorticoid (aldosterone) antagonist. Aldosterone is a natural hormone in the body that normally raises your blood pressure by increasing the amount of salt and water in your bloodstream. So by blocking aldosterone, Eplerenone helps your body get rid of extra salt and water, which then lowers your blood pressure. It’s unclear how exactly Eplerenone helps with heart failure. But it’s thought that the medication helps protect the heart. This will help reduce the risk of death in people with heart failure.

Eplerenone is typically dosed as 25 mg to 50 mg by mouth once daily. The max dose is 50 mg by mouth once or twice daily, depending on the condition being treated.

Eplerenone is a safe and effective treatment when used for FDA licensed indications. However, like all medications, they may give you unwanted side effects.
