We investigated the effects of organic Ca2+ channel blockers, diltiazem and verapamil, on the high voltage-activated P-type Ca2+ channels in freshly isolated rat Purkinje neurons. Both diltiazem and verapamil blocked P-type Ca2+ channel current without any change in the current-voltage relation. The block was concentration-dependent. In the presence of these agents, the inactivation curve was shifted to hyperpolarizing potentials. The characteristics of block of P-type Ca2+ channels by diltiazem and verapamil are similar to that of L-type Ca2+ channels. These results indicate that both benzothiazepine and phenylalkylamine react with P-type Ca2+ channels and suggest that some structural features common to which operate in both L-type and P-type Ca2+ channels may be involved in drug binding to these channels.
