Tolbutamide has been used as a model drug for an examination of the effects of eleven substituted imidazole compounds on hepatic metabolism in vivo. The 1-substituted compounds 1-methylimidazole, miconazole, clotrimazole and ketoconazole produced marked alterations in tolbutamide kinetics (increased half-life

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

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
Ji-Hong Shon et al.
Pharmacogenetics, 12(2), 111-119 (2002-03-05)
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
