Clinical Summary

A carbazole and propanol derivative that acts as a non-cardioselective beta blocker and vasodilator.

Carvedilol is used in the treatment of HYPERTENSION; ANGINA PECTORIS; and HEART FAILURE. It can also reduce the risk of death following MYOCARDIAL INFARCTION.

Therapeutic Applications

Carvedilol is used to treat high blood pressure and heart failure. It is also used after a heart attack to improve the chance of survival if your heart is not pumping well. Lowering high blood pressure helps prevent strokes, heart attacks, and kidney problems. This drug works by blocking the action of certain natural substances in your body, such as epinephrine, on the heart and blood vessels. This effect lowers your heart rate, blood pressure, and strain on your heart. Carvedilol belongs to a class of drugs known as alpha and beta blockers.

This can lead to blood clots forming, which can travel to other parts of your body (such as the lungs or legs) or increase your risk for stroke. In the United States, apixaban is also approved to treat certain types of blood clots (deep vein thrombosis-DVT, pulmonary embolus-PE) and to prevent them from forming again. Apixaban is an anticoagulant that works by blocking certain clotting proteins in your blood.
