Abstract
Recent findings indicate that induction of drug metabolism is regulated by activation of specific members of the nuclear receptor gene family. This minireview deals with the mechanisms by which phenobarbital and phenobarbital-type chemicals induce cytochrome P450 and other genes, and summarises the knowledge on the role of the constitutively active receptor CAR in the induction process. The potential implications of CAR-mediated induction for drug research and possible uses of CAR are also discussed.
