Brief Summary
The purpose of the study is to evaluate the benefit of treatment with oral dose of Ibodutant (code: MEN 15596) on IBS symptoms and the safety and tolerability of this therapy.
Detailed Description
Irritable Bowel Syndrome (IBS) is a functional disorder characterised by chronic or recurrent abdominal pain or discomfort associated with altered bowel habits.
