Ca++ antagonists

Any drug that acts by blocking the movement of Ca++ ions into cells.

As an antianginal they reduce the amount of free intercellular calcium which slows the breakdown of ATP. The result is a more efficient and controlled contraction of the cardiac muscle and vasodilation which improves oxygen supply. See antianginal for more detail.
