Cat. No.: HY-A0064 Purity: 99.98%
Handling Instructions

Verapamil hydrochloride ((±)-Verapamil hydrochloride) is a calcium channel blocker and a potent and orally active first-generation P-glycoprotein (P-gp) inhibitor. Verapamil hydrochloride also inhibits CYP3A4. Verapamil hydrochloride has the potential for high blood pressure, heart arrhythmias and angina research.

Description

Verapamil hydrochloride ((±)-Verapamil hydrochloride) is a calcium channel blocker and a potent and orally active first-generation P-glycoprotein (P-gp) inhibitor. Verapamil hydrochloride also inhibits CYP3A4. Verapamil hydrochloride 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]

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].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

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].

Cell Assay
[1]

Cells (1×105) are treated with 10 nM Bortezomib and/or 70 µM Verapamil for 16 hours and incubated for another 4 hours with Alamar-Blue. Activity of the mitochondrial dehydrogenase results in conversion of the coloring, which is followed by measurement of the absorption using a spectrophotometer[1].

Animal Administration
[3]

Rats[3]
Adult male Sprague-Dawley (SD) rats (250−350 g) are used. Verapamil (1 mg/kg) is injected i.v. into a femoral vein 10 min prior to ischemia. A sham group undergoes the same surgical procedures, except the suture underneath the LAD is left untied. In another series of experiment, arrhythmia is induced by Bay K8644, an L-type calcium channel agonist, at a dose of 0.1 mg/kg given i.v. into the FV. Verapamil (1 mg/kg) is administered 10 min prior to Bay K8644. All injections are performed within 30 sec.
