Metabolic screening in vitro: metabolic stability, CYP inhibition and induction

Automated, miniaturised assays are now commonplace within Discovery DMPK (drug metabolism and pharmacokinetics). These have evolved considerably since their inception around a decade ago, in-line with both technology and the desire to provide quality data comparable to more traditional analyses. Several formats exist for routine screening of metabolic stability and cyp (cytochrome P450; see Glossary) inhibition and induction, with the major focus being on in vitro systems using human-derived material. Data from other species remain valuable in assessing in vitro-in vivo projections and are pivotal to support safety assessment studies.:
