NCIt definition : An orally bioavailable semi-synthetic bile acid derivative and an agonist of the nuclear
bile acid receptor farnesoid X receptor (FXR) that may be used to lower hepatic exposure
to bile acids. Upon oral administration, obeticholic acid targets and binds to FXR
expressed in the liver and intestine, activating FXR-mediated bile acid, inflammatory,
fibrotic, and metabolic pathways. This suppresses the production of bile acid in the
hepatocytes and increases bile acid transport out of the hepatocytes, thereby reducing
hepatic exposure to bile acids. FXR plays an important role in bile acid homeostasis
and is involved in hepatic and intestinal inflammation and liver fibrosis.;
