Used primarily as a diuretic to treat fluid retention (edema) associated with heart failure, liver cirrhosis, kidney disease, and other cardiovascular conditions. It helps reduce excess fluid by increasing urine production, thereby decreasing swelling and lowering blood pressure. Also prescribed for hypertension management due to its ability to reduce blood volume and peripheral resistance. Its thiazide-like action makes it effective in long-term control of high blood pressure, often in combination with other antihypertensive agents.
