About this trial

This is an interventional treatment trial for Irritable Bowel Syndrome focused on measuring Iberogast, efficacy, safety

Eligibility Criteria

18 Years - undefined (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Patients of either sex aged >18 years
  • Patients meeting the Rome III irritable bowel syndrome (IBS) diagnostic criteria. IBS is defined as recurrent abdominal pain or discomfort at least 3 days/month in last 3 months (onset at least 6 months ago) associated with two or more of the following:

    • Improvement with defecation
    • Onset associated with a change in frequency of stool
    • Onset associated with a change in form (appearance) of stool
  • History of pain intensity with an average of worst abdominal pain in past 24 hours score of > 30 on a daily measured VAS (visual analogue scale) during screening phase

Exclusion Criteria:

  • Intake of STW5 within the last 5 years
  • Concomitant treatment during the study (including screening phase) with any medication that could influence the gastrointestinal function
  • Regular intake of nonsteroidal antiphlogistic drugs incl. COX-2-inhibitors (exception: acetylsalicylic acid for cardiovascular prevention up to 100 mg daily)
  • Patients with known hypersensitivity to any component of the trial drugs
  • History of eating disorders
  • Patients with a history of diseases with abdominal symptoms that can resemble IBS
  • Presence of any other acute or chronic gastrointestinal disorder
  • History of abdominal surgery (cholecystectomy and appendectomy can be tolerated when performed at least one year previously)
  • Known intolerance to azo dyes E 110 and E 151
