Metoprolol Succinate (50 mg) Extended-Release + Chlorthalidone (6.25 mg) Tablet is a combination antihypertensive medicine used to treat hypertension (high blood pressure) and reduce the risk of cardiovascular complications such as heart attack and stroke. Metoprolol, a selective beta-1 adrenergic blocker, lowers the heart rate and reduces the heart's workload, while Chlorthalidone, a thiazide-like diuretic, helps eliminate excess sodium and water from the body, thereby lowering blood pressure. Together, they provide effective 24-hour blood pressure control and improve overall cardiovascular health.
