Nisoldipine is a dihydropyridine-derivative L-type Ca
2+ channel receptor antagonist which relaxes arterial smooth muscle with high vascular selectivity and without changing serum calcium concentrations. This leads to prolonged vascular relaxation and lowering of blood pressure. In comparison with nifedipine [
N0528], nisoldipine have a longer duration of action. Nisoldipine is mainly metabolized by CYP3A4 in the liver. In addition, nisoldipine coat-core (CC) has been developed extended-release formulation that provides sustained 24-h blood pressure control. (The product is for research purpose only.)
