Absorption, Enterohepatic Circulation, and Fecal Excretion of Toxicants

Abstract

Enterohepatic circulation involves substances that are metabolized in the liver, excreted into the bile, and passed into the intestinal lumen where they are reabsorbed across the intestinal mucosa and returned to the liver via portal circulation. Intestinal metabolism of xenobiotics contributes to enterohepatic circulation and fecal excretion. There are several families of drug transporters that facilitate the influx and efflux from enterocytes and the influx and efflux from hepatocytes. More rational drug therapy and regulation of chemicals will be possible when more extensive information on the enterohepatic circulation of xenobiotics is available.
