Clinical trial: phase 2 study of lubiprostone for irritable bowel syndrome with constipation

Abstract

Lubiprostone significantly improved gastrointestinal symptoms of irritable bowel syndrome with constipation at all doses. Higher doses of lubiprostone, especially the 48 microg/day group, were associated with more gastrointestinal adverse events. From these data, the 16 microg/day dose demonstrated the optimal combination of efficacy and safety. These results warrant further study of lubiprostone for treatment of irritable bowel syndrome with constipation patients.
