Metoprolol tartrate is an immediate-release beta-blocker medication used to treat high blood pressure, chest pain (angina), and to reduce the risk of death or future heart attacks after a myocardial infarction. It is a prescription-only medication and is available in generic form under brand names like Lopressor®. 

Key Information

• Function: It works by slowing the heart rate and relaxing blood vessels, making it easier for the heart to pump blood throughout the body.

• Administration: Tablets are typically taken once or twice daily with food or immediately after a meal to reduce the risk of dizziness and ensure consistent absorption. The tablets should be swallowed whole or split at the score line if necessary, but not crushed or chewed.

• Dosage: The dosage is individualized based on the condition being treated, usually starting around 100 mg daily in divided doses for hypertension or angina.

• Important Warning: Do not stop taking metoprolol tartrate suddenly without consulting your doctor, as this can cause blood pressure to rise and increase the risk of a heart attack or stroke.
