Overview
Ursodiol is a bile acid available as 300 mg capsules suitable for oral administration. Ursodiol (ursodeoxycholic acid), a naturally occurring bile acid found in small quantities in normal human bile and in the biles of certain other mammals. It is a bitter-tasting, white or almost white crystalline powder freely soluble in alcohol; slightly soluble in acetone and in methylene chloride; very slightly soluble in water. The chemical name for ursodiol is 3α,7β-Dihydroxy-5β-cholan-24-oic acid (C 24 H 40 O 4 ). Ursodiol, USP has a molecular weight of 392.57. Its structure is shown below: Inactive Ingredients : Corn starch, colloidal silicon dioxide, magnesium stearate, talc, iron oxide red, titanium dioxide, gelatin. The imprinting ink contains shellac, black iron oxide and traces of potassium hydroxide. Image
Indications & Usage
Ursodiol is indicated for patients with radiolucent, noncalcified gallbladder stones < 20 mm in greatest diameter in whom elective cholecystectomy would be undertaken except for the presence of increased surgical risk due to systemic disease, advanced age, idiosyncratic reaction to general anesthesia, or for those patients who refuse surgery. Safety of use of ursodiol beyond 24 months is not established. Ursodiol is indicated for the prevention of gallstone formation in obese patients experiencing rapid weight loss.
Dosage & Administration
Gallstone Dissolution The recommended dose for ursodiol capsules treatment of radiolucent gallbladder stones is 8 - 10 mg/kg/day given in 2 or 3 divided doses. Ultrasound images of the gallbladder should be obtained at 6-month intervals for the first year of ursodiol capsules therapy to monitor gallstone response. If gallstones appear to have dissolved, ursodiol capsules therapy should be continued and dissolution confirmed on a repeat ultrasound examination within 1 to 3 months. Most patients who eventually achieve complete stone dissolution will show partial or complete dissolution at the first on-treatment reevaluation. If partial stone dissolution is not seen by 12 months of ursodiol capsules therapy, the likelihood of success is greatly reduced. Gallstone Prevention The recommended dosage of ursodiol capsules for gallstone prevention in patients undergoing rapid weight loss is 600 mg/day (300 mg b.i.d.).
Warnings & Precautions
WARNINGS Enteroliths in Patients with Risk for Intestinal Stenosis or Stasis There have been rare postmarketing reports of ursodiol-treated patients who developed enteroliths (bezoars) resulting in obstructive symptoms that required surgical intervention. These patients had medical conditions that predisposed them to intestinal stenosis or stasis (e.g., surgical enteroanastomoses, Crohn's disease). If a patient presents with obstructive gastrointestinal symptoms, hold ursodiol until a clinical evaluation has been conducted.
Contraindications
Ursodiol will not dissolve calcified cholesterol stones, radiopaque stones, or radiolucent bile pigment stones. Hence, patients with such stones are not candidates for ursodiol therapy. Patients with compelling reasons for cholecystectomy including unremitting acute cholecystitis, cholangitis, biliary obstruction, gallstone pancreatitis, or biliary-gastrointestinal fistula are not candidates for ursodiol therapy. Allergy to bile acids.

Drug Interactions
Bile acid sequestering agents such as cholestyramine and colestipol may interfere with the action of ursodiol by reducing its absorption. Aluminum-based antacids have been shown to adsorb bile acids in vitro and may be expected to interfere with ursodiol in the same manner as the bile acid sequestering agents. Estrogens, oral contraceptives, and clofibrate (and perhaps other lipid-lowering drugs) increase hepatic cholesterol secretion, and encourage cholesterol gallstone formation and hence may counteract the effectiveness of ursodiol.
