Adults and the elderly
Dissolution of gallstones:
A daily dose of 8 to 12mg/kg UDCA will produce cholesterol desaturation in the majority of cases. The measurement of the lithogenic index on bile-rich duodenal drainage fluid after 4-6 weeks of therapy may be useful for determining the minimum effective dose. The lowest effective dose has been found to be 4 mg/kg. The daily dose for most patients is 3 or 4 tablets, according to body weight. The dose should be divided into two administrations after meals, with one administration always after the evening meal.
The duration of treatment needed to achieve dissolution will not usually exceed 2 years, and should be monitored with regular cholecystograms. Treatment should be continued for 3-4 months after the radiological disappearance of gallstones.
Any temporary discontinuation of treatment, if prolonged for 3-4 weeks, will allow the bile to return to a state of supersaturation, and will extend the total time taken for litholysis. In some cases stones may recur after successful treatment.
Children and adolescents
