Carvedilol Prescription

Carvedilol lowers blood pressure and increases the output of the heart. Carvedilol is prescribed for people with congestive heart failure to increase survival and reduce the need for hospitalization. Carvedilol may be prescribed if you have survived a heart attack and now suffer from left ventricular dysfunction, a condition where the left side of the heart no longer pumps properly. Carvedilol is also prescribed to control high blood pressure. It is often prescribed with other drugs.

In some people, Carvedilol causes a drop in blood pressure when they first stand up, resulting in dizziness or even fainting. If this happens, sit or lie down and notify your doctor. Taking the drug with food reduces the chance of this problem. Even so, during the first month of therapy, or after a change in your dose, be careful about driving and operation of dangerous machinery.

Carvedilol contains the active ingredient carvedilol, which is a type of drug 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 prescribed 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.
