Carvedilol is a common form of Coreg used to treat high blood pressure and heart failure.
This drug can also be given to people whose hearts can not pump blood as well as before, because of a heart attack.
Carvedilol is a beta-blocker that relaxes your blood vessels and slows the heart rate so that your blood flow improves and your blood pressure goes down.
Approved by the Food and Drug Administration (FDA) in 1995, carvedilol is sold under the brand names Coreg and Coreg CR.
GlaxoSmithKline produces branded drugs, and several pharmaceutical companies produce common carvedilol.
Carvedilol is available in the form of a tablet and a sustained-release capsule, and is often prescribed in combination with other medicines.
