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].
In Vivo Intravenous Verapamil is highly effective in the termination of paroxysmal reciprocating atrioventricular tachycardia, whether associated with preexcitation or involving the atrioventricular node alone[2]. Given orally it is useful for the prophylaxis of atrioventricular reentry tachycardia, and also in modulating the atrioventricular nodal response in atrial fibrillation[2].
