| Description | Norverapamil hydrochloride (D591 hydrochloride) ((±)-Norverapamil hydrochloride) is an N-demethylated metabolite of Verapamil and it is an L-type calcium channel blocker and a P-glycoprotein (P-gp) function inhibitor. |
| In vitro | Norverapamil inhibits macrophage-induced tolerance and attains serum levels comparable to verapamil. Both verapamil and its primary metabolite, Norverapamil, are identified as mechanism-based inhibitors and substrates of CYP3A, exhibiting non-linear pharmacokinetics clinically. Furthermore, ((±)-Norverapamil hydrochloride) proves as effective as verapamil in inhibiting tolerance and killing intracellular M. tuberculosis in monotherapy, matching its efficacy against isoniazid and rifampicin tolerance [1][3]. |
| In vivo | Norverapamil hydrochloride (9 mg/kg; p.o.) exhibits a terminal half-life of 9.4 hours, an AUC of 260 ng ml−1 h, and a Cmax of 41.6 ng/mL[4]. |
