metoprolol Index
Metoprolol (Lopressor, Toprol XL) is a beta-adrenergic blocking agent, blocking the action of the sympathetic nervous system, a portion of the involuntary nervous system. Metoprolol is prescribed for patients with high blood pressure (hypertension), used to treat chest pain (angina pectoris) related to coronary artery disease, and is also useful in slowing and regulating certain types of abnormally rapid heart rates (tachycardias). Other uses for Metoprolol include the prevention of migraine headaches and the treatment of certain types of tremors (familial or hereditary essential tremors). It is important to be aware of the drug interactions related to Metoprolol, effects on pregnancy, as well as common side effects on the user.
