Ursodoxicoltaurine is the international nonproprietary name (INN) for the pharmaceutical form of tauroursodeoxycholic acid (TUDCA). It is also known as taurursodiol. Tauroursodeoxycholic acid is a naturally occurring hydrophilic bile acid which is the taurine conjugated form of ursodeoxycholic acid (UDCA). Humans have only trace amounts of tauroursodeoxycholic acid but bears have large amounts of tauroursodeoxycholic acid and ursodeoxycholic acid in their bile.^[1]
