      Nifedipine(Adalat), a potent vasodilator agent with calcium antagonistic action.;Target: Calcium ChannelNifedipine has been formulated as both a long- and short-acting 1,4-dihydropyridine calcium channel blocker. It acts primarily on vascular smooth muscle cells by stabilizing voltage-gated L-type calcium channels in their inactive conformation. By inhibiting the influx of calcium in smooth muscle cells, nifedipine prevents calcium-dependent myocyte contraction and vasoconstriction. A second proposed mechanism for the drug's vasodilatory effects involves pH-dependent inhibition of calcium influx via inhibition of smooth muscle carbonic anhydrase. Nifedipine is used to treat hypertension and chronic stable angina. Nifedipine is a useful anti-anginal agent that also lowers blood pressure. Nifedipine is a dihydropyridine calcium channel blocker. It is also commonly used for the small subset of pulmonary hypertension patients whose symptoms respond to calcium channel blockers [1, 2]. MedChem Express HY-B0284
