Substances are said to undergo an enterohepatic circulation (EHC) when they are excreted into the bile, pass into the lumen of the intestine, are reabsorbed and then return to the liver via the circulation. Many endogenous and exogenous substances can undergo an EHC.

The principal components of bile are the conjugated bile acids, cholesterol, and phospholipid, but in addition to these major components there is a vast array of minor components. Some of these are waste products of metabolism excreted by secretion in the bile, for example, bilirubin and the bile pigments.

Enterohepatic circulation of N-acetyl-leukotriene E4
Prostaglandins, 1987N-Acetyl-leukotriene E4, the end product of leukotriene C4 metabolism in the mercapturic acid pathway, was rapidly eliminated from the blood circulation into the bile of rats. Part of the N-acetyl-leukotriene E4 secreted from bile into the intestine underwent enterohepatic circulation.

Enterohepatic Circulation of Tetracycline in Rats
Journal of Pharmaceutical Sciences, 1975The absorption of tetracycline hydrochloride excreted in the bile of rats was evaluated using the insitu intestinal preparation. For comparative purposes, the absorption of the drug from an aqueous solution having the same pH as that of the bile was also determined.

The enterohepatic circulation in glutethimide intoxication
Clinical Pharmacology & Therapeutics, 1970The role of the enterohepatic circulation in glutethimide (Doriden) metabolism and toxicity was investigated in patients and dogs undergoing biliary drailwge. Bile collected after the oral or parenteral administration of glutethimide contained insignificant quantities of active and unmetabolized drug. Oral administration of glutethimide both before and

Pharmacokinetics of Drugs Subject to Enterohepatic Circulation
Journal of Pharmaceutical Sciences, 1979The influence of the changes in biliary excretion and reabsorption rates on the pharmacokinetics of drugs subject to enterohepatic circulation was examined analytically. A recently proposed two-compartment model with drug elimination occurring in each compartment was adapted to represent the body and the GI tract.

Bile salts, intestinal microflora and enterohepatic circulation
Digestive and Liver Disease, 2002Use of probiotic therapy implies an attempt to maintain the normal bacterial flora or to alter the bacterial flora so that organisms beneficial to the host are nurtured. We also know that the bacterial flora are essential in the deconjugation and transformation of bile acid metabolism.
