J Chromatogr A. 2008 Dec 26;1215(1-2):107-15. Epub 2008 Nov 7.

CYP-specific metabolites of melatonin (CYP1A2), nicotine (CYP2A6), bupropion (CYP2B6), repaglinide (CYP2C8), losartan (CYP2C9), omeprazole (CYP2C19 and CYP3A4), dextromethorphan (CYP2D6), chlorzoxazone (CYP2E1) and midazolam (CYP3A4) were all analyzed using the same LC/MS/MS method with a single analytical run, either after a one-at-a-time dose or cocktail-type dosing of the parent drugs.

RESULTS: Although much of the evidence is case report, dosage adjustments are clearly indicated for warfarin, olanzapine, clozapine and theophylline since they are metabolised by cytochrome P450 CYP1A2 and also have narrow therapeutic ratios.
Because the effect on hepatic microsomal enzymes is not related to the nicotine component of tobacco, nicotine replacement will not alter the effect.
