Drug-drug interactions (DDI) resulting in adverse outcomes cause approximately 3% of all hospitalizations annually in the United States. This costs the health care system over a billion dollars. Fortunately, many aspects of DDI are predictable based on the increasing understanding of the mechanisms of altered absorption, distribution, metabolism and excretion (ADME).

The pregnane X receptor (PXR; NR1I2) is a key player in DDI and several other nuclear receptors have been found to be xenobiotic/drug sensing receptors. These receptors help explain how one drug affects the pharmacokinetics of another by inducing drug metabolism and transport. These xenobiotic/drug sensing receptors belong to the family of ligand-activated transcription factors known as nuclear receptors.
The important xenobiotic sensing and drug metabolism inducing systems can vary greatly between animal species, causing difficulties in animal trials. Since pharmacokinetic interactions are often examined in laboratory animal models, it is important to understand these species differences when trying to choose the correct animal model.

Register for this webinar to learn about various drug screening assays that are available for identifying potential DDI in vitro. Drug screening assays improve drug safety and allow for the prioritization of drug candidates. PXR and several other important xenobiotic sensing and drug metabolism inducing systems will be described. These include Aryl hydrocarbon receptor (AhR), constitutive androstane receptor (CAR), Farnesoid X Receptor (FXR) and Nuclear factor-erythroid factor 2-related factor 2 (Nrf2).
The featured speaker will also discuss how in vitro assays can be used for species extrapolation of pharmacokinetic interactions for common laboratory animal models. These in vitro assays save time and money lost from pursuing candidates that may fail in animal or clinical trials.
