Metoprolol Succinate (50 mg) Extended-Release + Cilnidipine (10 mg) Tablet is a combination antihypertensive medicine used for the treatment of hypertension (high blood pressure) and to reduce the risk of cardiovascular complications. Metoprolol, a selective beta-1 adrenergic blocker, lowers heart rate and decreases the heart's workload, while Cilnidipine, a dual L-type and N-type calcium channel blocker, relaxes blood vessels and reduces sympathetic nerve activity. Together, they provide sustained 24-hour blood pressure control, improve cardiovascular function, and help protect the heart, brain, and kidneys from hypertension-related damage.
