| Description | Verapamil (CP-16533-1) is a calcium channel blocker and an orally active and effective inhibitor of P-gp. Verapamil inhibits CYP3A4 and can be used in studies about the treatment of high blood pressure, heart arrhythmias, and angina research. |
| Targets & IC50 | Kv1.5 channel:5.1 ± 0.5 μM (currents), K+ channel (hERG):3.8 ± 0.2 μM (currents), Delayed outwardly rectifying K+ current:11 μM, Kv1.1 channel:14.0 ± 2.7 μM (currents), P-gp:1.1 μM (Ki) |
| In vitro | Verapamil inhibits the EverFluor FL Verapamil (EFV) uptake by TR-iBRB2 cells with an IC50 of 98.0 μM in a concentration-dependent manner[1]. |
| In vivo | Verapamil (1 mg/kg;i.v.) 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[3]. Verapamil(oral) is useful for the prophylaxis of atrioventricular reentry tachycardia, and also in modulating the atrioventricular nodal response in atrial fibrillation[4]. |

For example, if the intended dosage is 10 mg/kg for animals weighing 20 g , with a dosing volume of 100 μL per animal, and a total of 10 animals are to be administered, using a formulation of 
10% DMSO+ 40% PEG300+ 5% Tween 80+ 45% Saline/PBS/ddH2O , the resulting working solution concentration would be 2 mg/mL.Dissolve 2 mg of the compound in 100 μL DMSO to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.
1) Add 100 μL of the DMSO stock solution to 400 µL PEG300 and mix thoroughly until the solution becomes clear.
2) Add 50 µL Tween 80 and mix well until fully clarified.
3) Add 450 µL Saline,PBS or ddH2O and mix thoroughly until a homogeneous solution is obtained.
