[ 1 ] - Preparation and in vitro evaluation of a novel chitosan-based hydrogel for injectable delivery of enrofloxacin

BACKGROUND: The development of injectable sustained-release products are of great interest to veterinary pharmaceuticals and animal health business. Recently, great attention has been paid to in situ gel-forming chitosan/beta-glycerophosphate (chitosan/β-GP) solutions due to their good biodegradability and thermosensitivity. OBJECTIVES: The general aim of this study was to prepare a novel in si...

[ 2 ] - Preparation and evaluation of a thermosensitive liposomal hydrogel for sustained delivery of danofloxacin using mesoporous silica nanoparticles

Background: Sustained release delivery system can reduce the dosage frequency and maintain the therapeutic level of drugs for a longer time. Biodegradable, biocompatible and thermosensitive chitosan-beta-glycerophosphate (C-GP) solutions can solidify at body temperature and maintain their physical integrity for a longer duration. OBJECTIVES: To develop a novel delivery system based on the integ...

[ 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-Methyl​enedioxy​methamphetamine (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...
