Summary

This study tests whether the drug ramosetron can reduce belly pain, bloating, and diarrhea in people with diarrhea-predominant irritable bowel syndrome (IBS-D). About 76 adults aged 18–65 will receive either ramosetron or a placebo daily for 4 weeks, along with a low-FODMAP diet and lifestyle advice. Symptoms will be checked using a standard severity score at 4 and 8 weeks to see if the drug provides meaningful relief.
