What Is Metoprolol Tartrate 50mg?
Metoprolol tartrate is a beta-blocker medication that works by slowing the heart rate and reducing the force of the heart's contractions, which lowers blood pressure and decreases the heart's demand for oxygen. It is FDA-approved to treat hypertension (high blood pressure), long-term management of angina pectoris (chest pain), and to reduce the risk of cardiovascular death in patients who have had a heart attack. Metoprolol tartrate is the immediate-release form of metoprolol and is typically taken two or more times daily with or immediately after meals. It is sold under the brand name Lopressor and is available only with a prescription.
