Brief Summary

Though ursodeoxycholate acid (UDCA) is the well known effective therapy for PBC,clinical effectiveness of UDCA may be limited by its poor absorption and extensive biotransformation.The more hydrophillic bile acid tauroursodeoxycholate (TUDCA) is the active ingredients of UDCA,and has been approved by state food and drug administration in China for treatment of cholesterol stones.So it is necessary to verify the efficacy and safety of TUDCA in the treatment of adult primary biliary cirrhosis. In this randomized, double-blinded, double -dummy, parallel-controlled and multicenter clinical trial, we detect the proportion of patients who had AKP decline more than 25% as the primary outcome;decline of ALP,total bilirubin, GGT,ALT and AST as secondary outcomes after patients were treated with TUDCA or UDCA for 24 weeks.

Outcome Measures

Primary Outcomes (1)

  • Efficiency is defined as the patients composition whose ALP level of serum decreased more than 25% compared to baseline at treatment for 24 weeks.

    After 24 weeks of treatment, calculate the rate of patients whose ALP level of serum ALP decreased more than 25% compared to the baseline. After 48 weeks of treatment, calculate the rate of patients whose ALP level of serum ALP decreased more than 40% compared to the baseline.

    48 weeks

Secondary Outcomes (1)

  • The change of laboratory parameters about liver function

    48 weeks
