Not Medical Advice: Metoprolol tartrate is a beta-adrenergic blocking agent (beta-blocker). It works by decreasing the amount of work the heart has to do (reduces chest pain) and the amount of blood the heart pumps out (lowers high blood pressure).
Metoprolol tartrate is also used to stabilize the heart rhythm in conditions in which the heart is in an irregular rhythm or beating too fast.
Metoprolol tartrate is used for curing high blood pressure, alone or with other drugs; long-term treatment of chest pain; and decreasing the risk of death because of heart problems in patients who have had a heart attack. It might also be used for other conditions as determined by your physician.
