Clinical Trial Summary

The purpose of this research study is to determine how Lubiprostone, a medication used to treat irritable bowel syndrome with constipation predominant symptoms (IBS-C), works to reduce clinical pain. Lubiprostone acts in the small intestine to cause an increase in the secretion of chloride, water and sodium. The increased fluid causes food residue to move through the bowel more quickly and makes the stools softer. First, we want to test the idea that Lubiprostone works by making a person less sensitive to pain. Second, we want to confirm that Lubiprostone decreases the time it takes fecal matter to travel through your GI tract, referred to as transit time.


Clinical Trial Description

Subjects will be enrolled in an 8-week study requiring a total of 7 visits to the UNC Center for Clinical and Translational Research. The protocol is divided into 4 two-week periods: (1) Two-week baseline diary symptom monitoring, followed by a barostat test of pain sensitivity. (2) Two-week treatment with either Lubiprostone or placebo, with daily symptom diary recording and barostat test of pain sensitivity at the end. In addition, patients will be tested for whole gut transit time by the radio-opaque marker (Sitzmark) technique in the second week. (3) Two-week washout period, during which patients will continue the symptom diary. (4) Two-week crossover to Lubiprostone or placebo, identical to the second two-week period. ;
