Metoprolol Succinate (50 mg) Extended-Release Tablet is a cardioselective beta-1 adrenergic blocker used to treat hypertension (high blood pressure), chronic stable angina, chronic heart failure, and to reduce the risk of cardiovascular complications following a heart attack. It works by slowing the heart rate, reducing the force of heart contractions, and lowering blood pressure, thereby decreasing the heart's workload and oxygen demand. The extended-release formulation provides continuous 24-hour therapeutic action with convenient once-daily dosing.
