Metoprolol

What Is Metoprolol?

Metoprolol is an oral medication used to treat a wide range of cardiovascular conditions. It is most commonly prescribed for high blood pressure (hypertension), but it is also used to manage:

• Angina (chest pain)

• Ventricular tachycardia

• Supraventricular tachycardia

• Congestive heart failure

• Acute myocardial infarction (heart attack)

• Long QT syndrome

• Vasovagal syncope

• Migraine prevention

• Symptoms of hyperthyroidism

• Certain anxiety disorders

Metoprolol is widely used because of its effectiveness and safety profile when taken as prescribed.

How Metoprolol Works

Metoprolol is a beta-blocker. It works by blocking beta receptors in the heart and blood vessels, which:

• Lowers blood pressure

• Reduces heart rate

• Decreases strain on the heart

Because of these effects, Metoprolol is helpful in treating many conditions related to high blood pressure and abnormal heart rhythms.
It is also known under brand names such as Lopressor®, Betaloc®, Selokeen®, and Neobloc®.
