Diltiazem hydrochloride is a calcium channel blocker that inhibits the transmembrane influx of extracellular calcium ions. Diltiazem hydrochloride is used in studies related to tumor and cardiovascular diseases. Diltiazem causes a dose-dependent inhibiton of contractions as well as Ca2+ influx stimulated by alpha adrenoceptor activation and high-K+ depolarization. Diltiazem also inhibits the Na-dependent Ca-efflux from heart mitochondria.
Diltiazem improves the cardiac microcirculation and function in an experimental model of hyperthyroidism in rats. Oral administration of diltiazem (100 mg/kg) reduces the blood pressure of SHR.
