[ 1 ] - Gender Dependency in Streoselective Pharmacokinetics of Tramadol and Its Phase I Metabolites in Relation to CYP2D6 Phenotype in Iranian Population
The stereoselective pharmacokinetic of Tramadol (T) and its main metabolites concerning the influence of CYP2D6 phenotype and gender on the phase I metabolism of this compound was studied after administration of 100 mg single oral dose of racemic T to 24 male and female subjects. The pharmacokinetic parameters were estimated from plasma concentrations of the analytes enantiomers. The metabolic ...

[ 3 ] - Imatinib metabolism and disposition in isolated rat perfused liver
Imatinib is an orally administered tyrosine kinase inhibitor which inhibits the Bcr-Abl protein-tyrosine kinase with high selectivity. Imatinib is rapidly absorbed from the gut, after oral intake and has an almost absolute bioavailability of 98%. The metabolism of imatinib is mediated by the cytochrome P450 (CYP) isoenzymes in the liver and gut wall. CGP74588 is a major active metabolite of ima...
[ 4 ] - Evaluation of changes in cytochrome P450 2C19 activity in type 2 diabetic rats before and after treatment, by using isolated perfused liver model
Objective(s): Alteration in drug metabolism is very likely in diabetes mellitus. This study assessed changes in CYP2C19 enzymatic activity in the liver using omeprazole as a probe in the animal model of type II diabetes (T2DM) before and after treatment with metformin and cinnamon.Materials and Methods: Twenty-eight male Wistar rats were...
[ 5 ] - Effect of 3,4-Methylenedioxymethamphetamine on Liver CYP2C19 Enzyme Activity in Isolated Perfused Rat Liver Using Omeprazole Probe
Background and purpose: This study aimed at investigating the effects of 3,4-Methylenedioxymethamphetamine (MDMA) on liver cytochrome 2C19 enzyme activity, which is a major liver enzyme in the metabolism of a wide range of drugs, using omeprazole as a probe of the CYP2C19 activity in isolated perfused rat liver. Materials and methods: This experimental study was done in 20 male Sprague–Da...
