Ursodeoxycholic acid (UDCA), also known as ursodiol, is a secondary bile acid, produced in humans and most other species from metabolism by intestinal bacteria. It is synthesized in the liver in some species, and was first identified in bile of bears of genus Ursus, from which its name derived.^[8] In purified form, it has been used to treat or prevent several diseases of the liver or bile ducts.

It is available as a generic medication.^[9]^[10]
