PXR is a key regulator for the expression of CYP 3A4 which is involved in the metabolism of majority of clinical drugs. Induction of PXR has been known to be associated with pharmacokinetic drug interactions.
AhR is involved in regulation of the expression of certain CYP isoforms. Phytochemicals could be the AhR agonists and induction of AhR could play a role in herb-drug interation.
