Abstract

Preclinical prediction of intestinal drug absorption is a continuous challenge in drug development. The absorption of a drug from the gastrointestinal tract is a complicated process, involving passive membrane permeability parameters as well as many active transport and metabolism components. Therefore, well characterised and reliable in vitro methods for studying drug absorption are constantly devised and under refinement. In this work, the Caco-2 cell line, a widely used model for intestinal drug absorption, was assessed as a platform to study the interplay of phase II metabolism and MRP (multidrug resistance associated protein) -mediated efflux. Expression and function of several metabolic enzymes and efflux proteins have been observed...
