Tiazac is a calcium-channel blocker. Tiazac affects the amount of calcium found in your heart and muscle cells. This results in relaxation of blood vessels, which can reduce the amount of work the heart has to do.

Tiazac reduces high blood pressure (hypertension). Tiazac is not a cure. Tiazac may also be used to relieve angina (chest pain).

Tiazac may also be used for purposes other than those listed in this medication guide.

Tiazac belongs to a group of medicines called calcium channel blockers, which act on the heart and blood vessels.

Tiazac slows the movement of calcium through cells, which has two results. Firstly, it decreases the rate at which the heart beats. As a result, the heart uses less energy and the pain of angina is prevented or relieved. Secondly, it has a mild widening effect on blood vessels and therefore reduces blood pressure.

Tiazac is mainly used in the treatment

Tiazac should be taken before meals and at bedtime. Tiazac capsules may be swallowed whole or opened and sprinkled on a spoonful of applesauce. Swallow the applesauce immediately, without chewing, and wash it down with a glass of cool water.
