Decreases the cholesterol content of bile and bile stones by reducing the secretion of cholesterol from the liver and the fractional reabsorption of cholesterol by the intestines. Mechanism of action in primary biliary cirrhosis is not clearly defined.
Undergoes extensive enterohepatic recycling; following hepatic conjugation and biliary secretion, the drug is hydrolyzed to active ursodiol, where it is recycled or transformed to lithocholic acid by colonic microbial flora; during chronic administration, ursodiol becomes a major biliary and plasma bile acid constituting 30% to 50% of biliary and plasma bile acids
Feces; urine (<1%)
Use: Labeled Indications
Gallstones (capsules only):
For patients with radiolucent, noncalcified gallbladder stones less than 20 mm in greatest diameter in whom elective cholecystectomy would be undertaken except for the presence of increased surgical risk caused by systemic disease, advanced age, idiosyncratic reaction to general anesthesia, or for those patients who refuse surgery. Safety for use of ursodiol beyond 24 months is not established.
For the prevention of gallstone formation in obese patients experiencing rapid weight loss.
Primary biliary cirrhosis (tablets only): For the treatment of patients with primary biliary cirrhosis (PBC).

Do not administer with aluminum-based antacids or bile acid sequestrants. If aluminum-based antacids are needed, administer 2 hours after ursodiol; administer ursodiol 5 hours or more after bile acid sequestrants (Rust, 2000). Urso Forte can be split into halves for appropriate dosage; do not chew. Urso and Urso Forte should be taken with food.
Urso and Urso Forte should be taken with food.
Actigall: Store at 25°C (77°F); excursions permitted to 15°C to 30°C (59°F to 86°F).
Urso: Store at 20°C to 25°C (68°F to 77°F).
Urso Forte: Store at 20°C to 25°C (68°F to 77°F). When broken in half, scored Urso Forte 500 mg tablets maintain quality for up to 28 days when kept in current packaging and stored at 20°C to 25°C (68°F to 77°F). Split tablets should be stored separately from whole tablets due to bitter taste.
Aluminum Hydroxide: May decrease the serum concentration of Ursodiol. Management: Consider administration of ursodiol 2 hours before or 6 hours after aluminum-containing antacid products to prevent adsorption in the gastrointestinal tract. Consider therapy modification
Bile Acid Sequestrants: May decrease the serum concentration of Ursodiol. Management: Administer ursodiol 5 hours or more after bile acid sequestrants to minimize ursodiol adsorption in the gastrointestinal tract. Monitor for decreased therapeutic effects of ursodiol in patients receiving bile acid sequestrants. Consider therapy modification
Estrogen Derivatives: May diminish the therapeutic effect of Ursodiol. Monitor therapy
Fibric Acid Derivatives: May diminish the therapeutic effect of Ursodiol. Monitor therapy
Nitrendipine: Ursodiol may decrease the absorption of Nitrendipine. Management: Consider therapeutic alternatives. If concomitant therapy cannot be avoided, avoid simultaneous administration. Consider therapy modification

Concerns related to adverse effects:
• Biliary obstruction: Maintain bile flow during therapy to prevent biliary obstruction.
• Hepatic effects: Use with caution in patients with chronic liver disease; monitor liver function tests monthly for the first 3 months, and every 6 months thereafter or as clinically necessary. Discontinuation of therapy may be necessary with significant elevations in liver function tests.
• Appropriate use: Gallbladder stone dissolution may take several months of therapy; complete dissolution may not occur and recurrence of stones within 5 years has been observed in up to 50% of patients. Patients should be cautiously selected for therapy, consider alternative treatments. Specific treatments should be initiated in patients with ascites, hepatic encephalopathy, variceal bleeding, or if an urgent liver transplant is necessary.
• Nonvisualizing gallbladder: Use with caution in patients with a nonvisualizing gallbladder; therapy should be discontinued if gallbladder nonvisualization occurs during treatment.
Gallstone disease: ALT, AST, sonogram
Hepatic disease: Monitor liver function tests (GGT, AST, ALT, bilirubin, and alkaline phosphatase) monthly for the first 3 months and every 6 months thereafter or as clinically necessary.
Pregnancy Risk Factor
Adverse events have not been observed in animal reproduction studies. Ursodiol (ursodeoxycholic acid) is the treatment of choice for intrahepatic cholestasis of pregnancy (Kremer, 2011).
• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)
• Patient may experience dizziness, headache, back pain, nausea, vomiting, constipation, diarrhea, abdominal pain, or heartburn (HCAHPS).
• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
