Tauro-Obeticholic acid is an active metabolite of Obeticholic acid. Obeticholic acid is an orally bioavailable farnesoid-X receptor (FXR) agonist.In Vitro: Obeticholic acid is conjugated with taurine in the liver to form Tauro-obeticholic acid, which is secreted into bile. Microorganisms in the ileum and colon can deconjugate Tauro-obeticholic acid, converting it into the parent drug, which may then be reabsorbed or excreted in faeces.
