An analytical method has been developed to determine simultaneously the verapamil and norverapamil enantiomers in human plasma using capillary electrophoresis. Among the cyclodextrins tested as chiral selector, only trimethyl-beta-cyclodextrin was suitable to resolve the four enantiomers. The analysis was achieved

Verapamil is known to be a P-glycoprotein (P-gp) substrate and norverapamil is formed via hepatic cytochrome P450 (CYP 3A) in the rat. Epigallocatechin gallate (EGCG), a flavonoid, was reported to be an inhibitor of both P-gp and CYP3A. Hence, it

The aim was to investigate the effect of Huang-Lian-Jie-Du-Decoction (HLJDD) on the pharmacokinetic behaviour of verapamil in rats. Rats orally received 3.33 g/kg of HLJDD extract for 14 days, and pharmacokinetics of verapamil was investigated after oral and intravenous verapamil.

A simple, accurate and selective LC-MS/MS method was developed and validated for simultaneous quantification of ten antiarrhythic drugs (diltiazem, amiodarone, mexiletine, propranolol, sotalol, verapamil, bisoprolol, metoprolol, atenolol, carvedilol) and a metabolite (norverapamil) in human plasma. Plasma samples were simply pretreated

The aims of the study are to develop and evaluate an in vitro rat intestine segmental perfusion model for the prediction of the oral fraction absorbed of compounds and to assess the ability of the model to study intestinal metabolism.
