Therapeutic Actions
Inhibits the movement of calcium ions across the membranes of cardiac and arterial muscle cells; inhibition of transmembrane calcium flow results in the depression of impulse formation in specialized cardiac pacemaker cells, in slowing of the velocity of conduction of the cardiac impulse, in the depression of myocardial contractility, and in the dilation of coronary arteries and arterioles and peripheral arterioles; these effects lead to decreased cardiac work, decreased cardiac energy consumption, and increased delivery of oxygen to myocardial cells.
