What is the Meaning of Enterohepatic Circulation?

Enterohepatic Circulation is a physiological pathway describing the movement of certain substances from the liver, through the bile duct into the small intestine, and then back to the liver via the portal vein. This cyclical process is crucial for the efficient recycling of bile acids and plays a significant role in the pharmacokinetics and elimination of various endogenous compounds, including hormones and xenobiotics. The efficiency of this circulation directly influences the duration of a substance's biological effect and its overall systemic exposure.

What is the Origin of Enterohepatic Circulation?

The term is a compound derived from three anatomical and physiological elements: entero- referring to the intestines, hepatic- referring to the liver, and circulation denoting the cyclical movement. This anatomical circuit was recognized as a mechanism for recycling bile components and has since been understood to encompass the metabolism of many other substances. It highlights the close functional relationship between the digestive tract and the liver in maintaining metabolic homeostasis.

What is the Mechanism of Enterohepatic Circulation?

The process begins with the liver conjugating fat-soluble substances, such as metabolized steroid hormones or certain drug compounds, making them water-soluble for excretion into the bile. Once in the intestine, specific gut bacteria or intestinal enzymes, like beta-glucuronidase, can deconjugate the compound, rendering it lipid-soluble again. This newly deconjugated substance is then readily reabsorbed across the intestinal wall into the portal blood, returning it to the liver for potential re-entry into systemic circulation, thereby extending its half-life and biological activity.
