Gp inhibition's
WebP-Glycoprotein functions in the gut primarily to affect the rate rather than the extent of drug absorption (68) (see Chapter 4, Figure 4.2 ). However, P-gp increases substrate exposure to luminal CYP3A4 metabolism during the process of drug efflux. Consequently, coadministration of a CYP3A4–P-gp substrate along with a P-gp inducer may result ... WebThe P-glycoprotein (P-gp) inhibitor, verapamil, can be included to identify whether active efflux is mediated by P-gp (alternatively for definitive P‑gp substrate identification, we have a P-gp substrate identification assay using the MDCK‑MDR1 cell test system in which human P-gp is expressed in isolation and unlike Caco‑2, is not ...
