PRESCRIPTION ONLY: Spirolactone 100mg Tablet is a potassium-sparing diuretic used to treat conditions such as primary aldosteronism, hypertension, and heart failure. It works by blocking the effects of aldosterone, a hormone that causes the body to retain sodium and water. By reducing sodium and water retention, Spirolactone helps to lower blood pressure and reduce fluid buildup in the body. - Medisfera Bali Pharmacy
