About

Multicenter randomized controlled clinical trial comparing ebastine and mebeverine as treatment of irritable bowel syndrome

Trial rationale

  1. To perform a randomized superiority trial comparing the clinical efficacy of ebastine and mebeverine
  2. To evaluate the impact of treatment with ebastine compared to mebeverine on quality of life and quality-adjusted life years

Primary objective To provide further evidence of the superiority of histamine 1 receptor antagonism as novel treatment for patients with non-constipated IBS, as compared to mebeverine, one of the spasmolytics currently used as first line treatment of IBS.

Secondary objective(s) To provide evidence that the histamine 1 receptor antagonist ebastine is more effective in reducing abdominal pain compared to the commonly used antispasmodic mebeverine
