Metoprolol Succinate (25 mg) Extended-Release + Cilnidipine (10 mg) Tablet is a combination antihypertensive medication used for the treatment of hypertension (high blood pressure) and to reduce the risk of cardiovascular complications. Metoprolol, a selective beta-1 adrenergic blocker, slows the heart rate and reduces the heart's workload, while Cilnidipine, a dual L-type and N-type calcium channel blocker, relaxes blood vessels and suppresses excessive sympathetic nerve activity. This combination provides effective 24-hour blood pressure control, improves cardiovascular function, and helps protect vital organs such as the heart and kidneys from hypertension-related damage.
