Abstract Background The expression and activity of P-glycoproteins due to genetic or environmental factors may have a significant impact on drug disposition drug effectiveness or drug toxicity. Hence characterization of drug disposition over a wide range of conditions of these membrane transporters activities is required to better characterize drug pharmacokinetics and pharmacodynamics. This work aims to improve our understanding of the impact of P-gp activity modulation on tissue distribution of P-gp substrate. Methods A PBPK model was .
