An Open-Label Trial of Duloxetine for the Treatment of Irritable Bowel Syndrome

We hypothesize that duloxetine treatment will be associated with improvement in symptoms of IBS, particularly abdominal pain, in individuals without comorbid major depressive disorder. During this 12-week, open-label, outpatient study, male and female subjects between the ages of 18 and 65 years who have been diagnosed with irritable bowel syndrome (IBS) will be treated with open-label duloxetine.
