Physiologically-based pharmacokinetic (PB-PK) models provide a mechanism for reducing the uncertainty inherent in extrapolating the results of animal toxicity tests to man. This paper discusses a technique for incorporating data from in vitro studies of xenobiotic metabolism into in vivo PB-PK models. Methylene chloride is used as an example, and carcinogenic risk estimates incorporating PB-PK principles are presented.
