A simple HPLC/fluorescence method to detect hydroxytolbutamide (a major metabolite of the anti-diabetic drug tolbutamide) has been developed. The effects of nicotine and some of its metabolites on tolbutamide hydroxylation is described. An extraction procedure with diethyl ether was followed
Several recent in-vitro data have revealed that CYP2C19, in addition to CYP2C9, is also involved in the 4-methylhydroxylation of tolbutamide. We evaluated the relative contribution of CYP2C9 and CYP2C19 genetic polymorphisms on the disposition of blood glucose lowering response to
Tolbutamide is known to be metabolized by cytochrome P450 2C9 (CYP2C9), and the effects of the CYP2C9 amino acid polymorphisms *2 (Arg144Cys) and *3 (Ile359Leu) could be important for drug treatment with tolbutamide and for use of tolbutamide as a
British journal of pharmacology, 81(3), 557-562 (1984-03-01)
The effects of various drugs on the pharmacokinetics of tolbutamide have been examined in the rat. Phenobarbitone pretreatment caused a significant decrease in half life and area under the curve (AUC) and a significant increase in clearance and volume of
Use of tolbutamide as a substrate probe for human hepatic cytochrome P450 2C9.
