Description

Application

Verapamil hydrochloride has been used:

• to inhibit calcium oscillation in fertilized oocyte
• to block calcium channel, thereby blocking the action of IL-1β (interleukin-1β), resulting in membrane depolarization
• to investigate the effect of verapamil on cytotoxicity of 1,3-dilinoleoylglycerol (DLG)

Biochem/physiol Actions

α₁-adrenoceptor antagonist; L-type calcium channel blocker. Blocks L-type Ca²⁺ channels in smooth and cardiac muscle, induces apoptosis of human primary and metastatic colon adenocarcinoma cells in vitro. Drug resistance reversal agent acting on Pgp, e.g. decrease renal tubule elimination of digoxin. Increases basal ATPase activity of Pgp. Substrate of Cyp3A4 and CYP2C6.
