Metoprolol also reduces the force of contraction of heart muscle and thereby lowers blood pressure. By reducing the heart rate and the force of muscle contraction, metoprolol reduces the need for oxygen by heart muscle. Since heart pain (angina pectoris) occurs when oxygen demand of the heart muscle exceeds the supply of oxygen, metoprolol, by reducing the demand for oxygen, is helpful in treating heart pain. The FDA approved metoprolol in August 1978.

PRESCRIBED FOR: Metoprolol is prescribed for patients with high blood pressure (hypertension). It also is used to treat congestive heart failure and angina pectoris (heart pain) related to coronary artery disease. Metoprolol is also useful in slowing and regulating certain types of abnormally rapid heart rates (tachycardias). Other uses for metoprolol include the prevention of migraine headache, hyperthyroidism, and the treatment of certain types of tremors (familial or hereditary essential tremors).

SIDE EFFECTS: Metoprolol is generally well tolerated. Side effects include:
