“2 In basal conditions, 0.1 μm lacidipine reduced the action potential duration, associated with a decrease in the L‐type calcium current (Ica, L ) to 66 ± 4% of the control value, without a change in the current‐voltage relationship.”
“7 These results demonstrate that lacidipine selectively inhibits ICa, L in isolated cardiomyocytes and suggest that this effect occurs mainly through binding to the inactivated Ca2+ channels.”
