[Comparative effectiveness of ursodeoxycholic acid preparations in the treatment of biliary sludge]

In the clinical classification of cholelithiasis, biliary sludge (BS) is distinguished as the pre-stone stage. Ursodeoxycholic acid (UDCA) is a drug with an evidence base for effective and safe effects on BS. The therapeutic equivalence of various UDCA drugs remains an important issue for clinical practice.

To conduct a comparative analysis of the effectiveness of the use of UDCA: Ursofalk with other UDCA drugs for the treatment of BS in a fixed dose of 10 mg/kg of body weight.

The observation group consisted of 225 patients with various types of BS. In randomized groups, the comparison of the effectiveness of UDCA drugs in the dissolution of BS was determined by the data of ultrasound of the gallbladder. Dynamic ultrasound cholecystography using a standardized technique was performed to study the effect of the compared drugs on the contractile function of the liver. When analyzing the impact of ursotherapy on the clinical manifestations of BS, the dynamics of biliary pain syndrome and dyspeptic disorders were evaluated.

A comparative analysis of the effectiveness of UDCA drugs for BS lysis with a high degree of confidence established the advantage of Ursofalk: after 3 months in 80%, and after 6 months of therapy in 95.65% of patients, a regression of BS was detected. In the group of patients who took other UDCA, the corresponding indicators were 46.36% and 67.27%. The greatest effectiveness of ursotherapy was demonstrated in the BS variant by the type of suspension of hyperechogenic particles, the lowest in the variant by the type of putty-like bile in the form of mobile or fixed clots. In the last variant of BS, the relationship between the success of lysis with the extension of the UDCA intake period to 6 months and the preferred choice of Ursofalk was traced. Normalization of the contractile function of the gallbladder was noted in patients who took Ursofalk.

From the standpoint of therapeutic effectiveness, the drug of choice for the treatment of BS, regardless of its type, is Ursofalk, which has proven the best dynamics of BS litolysis, recovery of the contractile function of the gastrointestinal tract, and relief of clinical symptoms.
