Eplerenone Tablet IP 25 mg is a selective aldosterone receptor antagonist used to treat heart failure and high blood pressure. It works by blocking the effects of aldosterone, helping the body eliminate excess salt and water while retaining potassium. This reduces blood pressure, prevents fluid buildup, and protects the heart from damage, especially after a heart attack. Eplerenone is commonly prescribed for patients with chronic heart failure or left ventricular dysfunction.
