Below are some of the details of Carvedilol(generic)

Carvedilol is a non-selective beta blocker/alpha-1 blocker indicated in the treatment of mild to moderate congestive heart failure (CHF). It works by relaxing the blood vessels, slowing down the heart, and decreasing the amount of blood it pumps out. This decreases blood pressure, helps the heart pump more efficiently, and reduces the workload on the heart.
It is used for treating high blood pressure or certain types of heart failure. It may also be used after a heart attack to improve survival in certain patients. It may be used along with other medicines.
