Lopressor 50 mg: Uses, Dosage, Side Effects, Safety, and Frequently Asked Questions

What Is Lopressor 50 mg?

Lopressor 50 mg is a prescription medication containing metoprolol tartrate, a beta-blocker used to treat several cardiovascular conditions, including high blood pressure (hypertension), angina (chest pain), and to improve survival after a heart attack (myocardial infarction).

Lopressor works by slowing the heart rate and reducing the force with which the heart pumps blood. This lowers blood pressure, decreases the heart’s workload, and helps reduce the risk of serious cardiovascular complications.

Lopressor (metoprolol tartrate) is available in several tablet strengths, including:

• 25 mg
• 50 mg
• 100 mg

It is an immediate-release formulation and is different from metoprolol succinate, which is an extended-release form.
