Metoprolol tartrate is the immediate-release version of metoprolol, a commonly prescribed cardioselective beta blocker. Used for blood pressure or heart problems, metoprolol tartrate works by slowing the heart and reducing the force of its contractions. This reduces blood pressure and relieves the stress on the heart muscle. Doses are taken twice daily. Healthcare professionals have the option of prescribing extended-release metoprolol succinate so that only one dose per day is required.
