Effects of Smoking on the Pharmacokinetics of Erlotinib

Abstract

This study confirms that the pharmacokinetics of erlotinib is different in current smokers and nonsmokers. The observation that AUC(0-infinity) and C(24h) were significantly decreased in smokers compared with nonsmokers, and a smaller decrease in C(max) was observed, is consistent with increased metabolic clearance of erlotinib in current smokers.
