Evidence for a Modulated Receptor Mechanism of Calcium Channel Blockaded explanations for such phenomena as the selective depression of conduction in ischemic myocardium, suppression of tachycardias, and the selective action of lidocaine on ventricular vs. atrial tissue (4).

Calcium Antagonistic Agents: Uptake into Various Muscles and their Effects on Calcium Bindingpling of contraction from excitation. Their action can be greatly counteracted by increasing concentration of external calcium. Electrophysiological studies show that the mode of action of these drugs is due to a decrease of transmembrane conductance for calcium ions and, consequently, to a reduction of the slow inward calcium current.

By virtue of this differential effect, some of these calcium antagonists have been found to be useful in the treatment of angina pectoris.

Effects of Calcium Antagonistic Drugs on Various Heart Tissues, Including Blockade of the Slow Channe drugs, like verapamil, methoxy-verapamil (D600), and nifedipine also block the slow Na. channels of young embryonic chick hearts, these drugs are more accurately described as “slow channel blockers” (Shigenobu et al., 1974; Lee & Tsien, 1983; Kojima & Sperelakis, 1983).
