Metoprolol Tartrate (Prometin) 100mg Tablets are a beta-blocker used primarily to treat high blood pressure (hypertension), angina (chest pain), and to improve heart function in patients with heart failure. Each tablet contains 100mg of Metoprolol Tartrate, which works by blocking certain receptors in the heart, reducing the heart rate, and lowering blood pressure, thus reducing the workload on the heart. The pack contains 100 tablets, providing a convenient supply for long-term treatment as prescribed by a healthcare professional. Metoprolol is also used to reduce the risk of heart attacks and manage irregular heart rhythms.
