Absorption, Distribution and Excretion
The duodenal experiment indicates that dehydrocholic acid is absorbed from the proximal small intestine.
Administered dehydrocholic acid is excreted rapidly in bile as glycine- and taurine-conjugated bile acids.

Metabolism / Metabolites
The major site of metabolism is proposed to be the liver. The major metabolite accounting for 70% of total detectable metabolites is dihydroxymonoketo bile acid (3α,7α-dihydroxy-12-keto-5β-cholanoic acid). About 20% of metabolites is monohydroxydiketoacid (3α-hydroxy-7,12-keto-5β-cholanoic acid) and about 10% is cholic acid.

3,7,12-trioxo-5beta-cholanic acid is an oxo-5beta-cholanic acid in which three oxo substituents are located at positions 3, 7 and 12 on the cholanic acid skeleton. It has a role as a gastrointestinal drug. It is an oxo-5beta-cholanic acid, a 7-oxo steroid, a 12-oxo steroid and a 3-oxo-5beta-steroid. It is a conjugate acid of a 3,7,12-trioxo-5beta-cholan-24-oate.
Dehydrocholic acid is a synthetic bile acid that was prepared from the oxidation of cholic acid with chromic acid. It has been used for stimulation of biliary lipid secretion. The use of dehydrocholic acid in over-the-counter products has been discontinued by Health Canada.
A semisynthetic bile acid made from cholic acid. It is used as a cholagogue, hydrocholeretic, diuretic, and as a diagnostic aid.

Drug Indication
No approved therapeutic indications.

Mechanism of Action
It is proposed that dehydrocholic acid induces choleresis, which is associated with biliary lipid secretion and reduced secretion of endogenous and/or exogenous biliary components. Dehydrocholic acid may decrease bile phospholipid secretion due to a lack of micelle formation by dehydrocholic acid-produced bile. A study suggests that due to enhanced permeability of tight junctions in the canalicular membranes, dehydrocholic acid facilitates direct exchange between bile and plasma.

Pharmacodynamics
Following infusion of dehydrocholic acid (DHCA) in rats, the secretions of all the endogenous biliary bile acids were decreased within 30-60 minutes of infusion. Phospholipid secretion as well as cholesterol levels were also declined. The bile flow was increased after administration of dehydrocholic acid.
