Description

Manidipine (Manyper) is a lipophilic, third-generation, highly vasoselective dihydropyridine calcium antagonist with an IC50 of 2.6 nM. It causes systemic vasodilation by inhibiting the voltage-dependent calcium inward currents in smooth muscle cells. It is used clinically as an antihypertensive. At a holding potential of −37 mV, manidipine decreased the Ca2+ current at concentrations above 0.1 nM, and abolished it at 100 nM. The voltage-dependent effect of manidipine on the Ca2+ current may explain the weak negative inotropism of manidipine in ventricular muscles, and provide an electrophysiological basis for its vascular selectivity.
