Verapamil ((±)-Verapamil) 是一種鈣通道 (calcium channel) 阻滯劑,是一種有效的口服活性的第1代 P 糖蛋白 (P-gp) 抑制劑。Verapamil 能也抑制 CYP3A4

生物活性
Verapamil ((±)-Verapamil) is a calcium channel blocker and a potent and orally active first-generation P-glycoprotein (P-gp) inhibitor. Verapamil also inhibits CYP3A4. Verapamil has the potential for high blood pressure, heart arrhythmias and angina research[1][2][3].
IC50 & Target
Calcium channel[1]
Permeability-glycoprotein (P-gp)[1]
CYP3A4[1]
體外研究(In Vitro)
The EverFluor FL Verapamil (EFV) uptake by TR-iBRB2 cells is inhibited by cationic drugs, and inhibits by verapamil in a concentration-dependent manner with an IC50 of 98.0 μM[4].
體內(nèi)研究(In Vivo)
Given orally Verapamil is useful for the prophylaxis of atrioventricular reentry tachycardia, and also in modulating the atrioventricular nodal response in atrial fibrillation[2].
Verapamil is injected i.v. into a femoral vein prior to ischemia. Verapamil (1 mg/kg) significantly decreases the incidence of ventricular arrhythmias including premature ventricular contractions (PVC), ventricular tachycardia (VT) and ventricular fibrillation (VF) for 45-min coronary artery occlusion. Total arrhythmia scores are significantly increased when the heart is subjected to ischemia. Verapamil (1 mg/kg) significantly prevents the enhancement of total arrhythmia scores induced by ischemia[5].
