UniProtKB description:  Potent blocker of high-voltage-activated calcium ion channels in the nanomolar range, particularly the L-type channels in cerebellar granule cells. The sensitivity of L-, N- and P-type channels to CAC is tissue and species-dependent. Blocks the L-type current of cardiac cells, depressing cardiac contractility.
