In Vitro	Benzothiazepine Ca2+ antagonist diltiazem hydrochloride interacts with transmembrane segments IIIS6 and IVS6 in the α1 subunit of L-type Ca2+ channels[1]. Diltiazem causes a dose-dependent inhibiton of contractions as well as Ca2+ influx stimulated by alpha adrenoceptor activation and high-K+ depolarization. Diltiazem is roughly equally potent in inhibiting contractions induced by high-K+ and a low concentration of norepinephrine (NE)[2]. Diltiazem also inhibits the Na-dependent Ca-efflux from heart mitochondria. Both the (+)-optical isomers of the cis- and trans-forms of diltiazem inhibit Na-Ca exchange activity with comparable potency (IC50 of 10-20 μM)[3].
In Vivo	Diltiazem produces a noncompetitive inhibition of Ca2+-induced contractions of depolarized rabbit aorta. Furthermore, there is a lack of parallelism between the smooth muscle effects of removal of [Ca2+]ex and of addition of diltiazem[2]. Diltiazem improves the cardiac microcirculation and function in an experimental model of hyperthyroidism in rats. The treatment of hyperthyroid rats with losartan diltiazem (4.7±0.7%; P < 0.001) significantly reduces the percentage of fibrosis areas in the left ventricle [4]. In conscious spontaneously hypertensive rats (SHR), diltiazem dose-dependently decreases the blood pressure and increases the heart rate after intravenous administration (0.03--1 mg/kg). Oral administration of diltiazem (100 mg/kg) also reduces the blood pressure of SHR[5].
