Abstract

Transporters play a pivotal role in defining disposition, therapeutic outcome, and adverse reactions of medicines. P-glycoprotein (P-gp) is an efflux transporter that is constitutively expressed in barrier tissues and excretory organs, and has wide substrate specificity; consequently, it may be responsible for wide-ranging drug–drug interactions (DDIs). This chapter critically evaluates the utility and limitations of Caco-2 cells, a model for human intestinal epithelium that expresses most intestinal transporters, in assessing DDIs mediated by P-gp and other transporters.
