Contain the active ingredient : Verapamil HCL, which is a type of medicine called a calcium-channel blocker. This type of medicine acts on the heart and blood vessels. (NB. Verapamil is also available without a brand name, ie as the generic medicine.)

Verapamil works by slowing down the movement of calcium through muscle cells that are found in the heart and the walls of blood vessels. It does this by blocking 'calcium channels' on these muscle cells. Calcium is needed by the muscle cells in order for them to contract. By depriving them of calcium, verapamil causes the muscle cells to relax. This action of verapamil has two main effects; it slows down the rate at which the heart beats and it allows the blood vessels in the body to widen.

When the heart beats more slowly, the pressure at which the blood is pumped out of the heart is reduced. When the blood vessels in the body relax and widen, this decreases the resistance that the heart has to push against in order to pump the blood around the body. Both these actions reduce the pressure within the blood vessels. This means verapamil can be used to lower high blood pressure.

Slowing the heart rate also reduces the energy used by the heart to pump blood around the body. This in turn reduces the heart's need for oxygen. At the same time, widening the blood vessels improves the blood and therefore oxygen supply to the heart. Both these features mean that verapamil can be used in the management of angina.

The chest pain of angina is caused by insufficient oxygen supply to the heart. As verapamil improves this oxygen supply, and also reduces the effort the heart has to make to pump blood, it can be used to prevent angina attacks.

Verapamil is also used to slow down certain types of abnormally fast heartbeats, which could otherwise seriously undermine the pumping action of the heart and result in inefficient blood circulation around the body.

What is it used for?

High blood pressure (hypertension).

As a regular long-term treatment to prevent angina attacks.

Slowing down certain types of abnormally fast heartbeats (supraventricular tachycardia and atrial flutter/fibrillation).
