Detailed Description:

Irritable Bowel Syndrome (IBS) is a functional disorder characterised by chronic or recurrent abdominal pain or discomfort associated with altered bowel habits. This trial aims to evaluate the efficacy of Ibodutant in improvement of IBS symptoms through a daily oral administration, testing three dosages or placebo in IBS patients for 4-weeks. In each patient, the experimental clinical phase encompasses a screening/ 2-week run-in period (no study medication), followed by a 4-weeks treatment period and a 2-weeks treatment withdrawal period, for total study duration of 8 weeks in each patient.
