Bepridil hydrochloride hydrate ((±)-Bepridil hydrochloride hydrate) is a non-selective, long-acting Ca+ channel antagonist and Na+, K+ channel inhibitor, with antianginal and type I antiarrhythmic effects. Bepridil hydrochloride hydrate also acts as a cardiac Na+/Ca2+ exchange (NCX1) inhibitor. Bepridil hydrochloride hydrate can be used for the research of cardiovascular disorders[1][2][3][4][5].

In Vitro	Bepridil hydrochloride hydrate blockades of Ca2+-dependent action potentials in vascular smooth muscle of dog coronary artery[2]. Bepridil hydrochloride hydrate blocks Ca currents and Na currents with IC50s of 0.5 μM and 30 μM, respectively in cultured ventricular cells[4]. Bepridil hydrochloride hydrate decreases IKs under blockade of IKr with E4031 (5 μM), in a concentration-dependent manner[5].
In Vivo	Bepridil hydrochloride hydrate exhibits a half-life of averages 33±15 hours after single-dose administration[6].
