URSO 250® (ursodiol, 250 mg) and URSO Forte™ (ursodiol, 500 mg) are available as film-coated tablets for oral administration. Ursodiol (ursodeoxycholic acid, UDCA) is a naturally occurring bile acid found in small quantities in normal human bile and in larger quantities in the biles of certain species of bears. It is a bitter-tasting white powder consisting of crystalline particles freely soluble in ethanol and glacial acetic acid, slightly soluble in chloroform, sparingly soluble in ether, and practically insoluble in water.
URSO 250® and URSO Forte™ (ursodiol) tablets are indicated for the treatment of patients with primary biliary cirrhosis.

Colchicine or methotrexate, with ursodiol, are effective after 20 years in a subset of patients with primary biliary cirrhosis. [2011.09]
BACKGROUND & AIMS: The combination of ursodeoxycholic acid (UDCA), colchicine, and methotrexate (MTX) is effective therapy for a subset of patients with primary biliary cirrhosis (PBC) who do not respond to UDCA. However, the durability of the response is unclear. We investigated whether the response to combination therapy was durable... CONCLUSIONS: Treatment with the combination of UDCA and MTX or UDCA and colchicine led to sustained clinical remission in a subset of patients with PBC. The response to the combination of UDCA and MTX appeared to be more durable than to UDCA and colchicine. Copyright (c) 2011 AGA Institute. Published by Elsevier Inc. All rights reserved.
High-dose ursodeoxycholic acid is associated with the development of colorectal neoplasia in patients with ulcerative colitis and primary sclerosing cholangitis. [2011.09]
OBJECTIVES: Some studies have suggested that ursodeoxycholic acid (UDCA) may have a chemopreventive effect on the development of colorectal neoplasia in patients with ulcerative colitis (UC) and primary sclerosing cholangitis (PSC). We examined the effects of high-dose (28-30 mg/kg/day) UDCA on the development of colorectal neoplasia in patients with UC and PSC... CONCLUSIONS: Long-term use of high-dose UDCA is associated with an increased risk of colorectal neoplasia in patients with UC and PSC.
