Intestinal drug transporters in pathological states: an overview.

ABSTRACT: Emerging information suggests that gastrointestinal and systemic pathology states may affect expression and function of membrane transporters in the gastrointestinal tract. Altered status of the transporters could affect drug as well as endogenous compounds handling with subsequent clinical consequences. It seems that in some pathologies, e.g., liver or kidney failure, changes in the intestinal transporter function provide compensatory functions, eliminating substrates excreted by dysfunctional organs. A literature search was conducted on Ovid and Pubmed databases to select relevant in vitro, animal and human studies that have reported expression, protein abundance and function of intestinal drug transporters. The accumulated data suggest that gastrointestinal pathology (inflammatory bowel disease, celiac disease, cholestasis) as well as systemic pathologies (kidney failure, liver failure, hyperthyroidism, hyperparathyroidism, obesity, diabetes mellitus, systemic inflammation and Alzheimer disease) may affect drug transporter expression and function in the gastrointestinal tract. The altered status of drug transporters may provide compensatory activity in handling endogenous compounds, affect local drug actions in the gastrointestinal tract as well as impact drug bioavailability.
