Nilvadipine 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], nilvadipine have a longer duration of action and a greater vasodilatory effect. Nilvadipine is mainly metabolized by CYP3A4 in the liver. Nilvadipine is a poorly water soluble agent, and its solid dispersions have been developed to the solubility. (The product is for research purpose only.)
