Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of the study is to investigate whether renzapride will help alleviate the symptoms associated with constipation predominant irritable bowel syndrome in female patients.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Irritable bowel syndrome (IBS) is a chronic gastrointestinal disorder characterized by recurrent symptoms of abdominal pain/discomfort accompanied by disturbed bowel function.

In this study female patients with constipation predominant IBS will receive one of two dosing regimens of renzapride or placebo for 12 weeks. Patients will record the severity of their symptoms throughout the study. The results will be analysed to see if those patients who received renzapride had greater relief of their symptoms than did the patients who received placebo.
