Ondansetron for Irritable Bowel with Diarrhea?

Briefly noted: A selected summary (Gastroenterol 2014; 147: 527-28) reviews the potential utility of ondansetron (median dose in adult participants was 4 mg) for irritable bowel syndrome with diarrhea (IBS-D) based on a recent study (Link to full online journal article: Randomized Trial of Ondansetron for IBS-D in Gut).

Several limitations are discussed including patient dropout, crossover study design, and short term study (in chronic disease).  As such, even though this study provides some evidence that ondansetron may be helpful for IBS-D, this probably needs “to be replicated in large-scale, parallel group, randomized, placebo-controlled trials…with longer duration of therapy..before the true place of ondansetron in the management of IBS-D is known.”
