Gallbladder stone dissolution with Ursodiol treatment requires months of therapy. Complete dissolution does not occur in all patients and recurrence of s tones within 5 years has been observed in up to 50% of patients who do dissolve their s tones on bile acid therapy. Patients should be carefully s elected for therapy with ursodiol, and alternative therapies should be considered.
- 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 AND ADMINISTRATION
The recommended dose for Ursodiol 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 therapy to monitor gallstone response. If gallstones appear to have dissolved, Ursodiol 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 therapy, the likelihood of success is greatly reduced.
The recommended dosage of Ursodiol for gallstone prevention in patients undergoing rapid weight loss is 600 mg/day (300 mg b.i.d.).
