Coreg (Carvedilol) is an alpha and beta blocker used to treat high blood pressure and congestive heart failure.
How does it work?
This medicine contains the active ingredient carvedilol, which is a type of medicine called a beta-blocker.
Beta-blockers block beta-receptors in the heart, lungs and other organs of the body. Blocking these receptors prevents the action of two chemicals called noradrenaline and adrenaline that occur naturally in the body. These are often referred to as the 'fight or flight' chemicals, as they are responsible for the body's reaction to stressful situations.
Carvedilol mainly blocks beta-receptors in the heart, which causes the heart to beat more slowly and with less force. This means that the heart uses less energy and so requires less oxygen from the blood. The pain of angina is caused by not enough oxygen reaching the heart when it's workload is increased, eg during exercise. Carvedilol prevents this pain by decreasing the oxygen demand of the heart, so that it always has a sufficient supply.
Due to the heart beating more slowly and with less force, the pressure at which blood is pumped out of the heart to the rest of the body is reduced. This is one way in which carvedilol reduces blood pressure.
Carvedilol also blocks receptors called alpha-receptors that are present on the walls of blood vessels. Blocking these receptors causes the blood vessels to widen, which means that there is more space and less resistance in the blood vessels. This is another mechanism by which the pressure in the blood vessels is lowered.
The widened blood vessels also allow more blood to reach the heart, which is another way in which carvedilol prevents the pain of angina.
Overall, carvedilol decreases the effort required by the heart to pump blood around the body and so can also be used to treat chronic heart failure, where the pumping action of the heart has become less effective.
Because carvedilol widens the blood vessels and maintains the blood flow to the extremities, it rarely causes the cold extremities (hands and feet) that can occur in people taking other beta-blockers.
