Nifedipine: A Short-Acting Dihydropyridine Calcium Antagonist

Nifedipine is a short-acting dihydropyridine calcium antagonist. It selectively inhibits the transmembrane influx of calcium ions into cardiac and vascular smooth muscle without altering serum calcium concentrations, and induces a relaxation of the muscle. Because of the dilation of resistance vessels, blood pressure falls. Nifedipine is almost completely metabolized by cytochrome P450 3A4 (CYP3A4) in the liver. Nifedipine is a poorly water soluble agent and rapidly metabolized resulting in decreased bioavailability, and then the short-acting can provide increased the risk of stroke et al. Therefore, nifedipine slow-release formulations have been developed. (The product is for research purpose only.)
