Carvedilol, marketed under the brand name Coreg among others, is a beta blocker. Beta blockers are medications used to reduce blood pressure in the body, regulate heart rhythm and reduce the risk of a second heart attack after the first one. Lowering blood pressure minimizes the risk of stroke, heart attack and complications in the kidney. Furthermore, low blood pressure also reduces the load on the heart as it is relatively easier to pump blood against low blood pressure.
Beta blockers work by affecting the circulation of blood within and outside the heart as it flows through the arteries and veins. Beta-blockers function by blocking the beta receptors present in the heart and other cells, preventing it from reacting to stress and making it more relaxed. Carvedilol is available in capsule and tablet forms, in various doses strengths.
