Irritable bowel syndrome (IBS) is a chronic gastrointestinal disorder characterized by alterations in motility, stool consistency and frequency, and urgency. It is generally classified into three subtypes: constipation-predominant, diarrhea-predominant (IBS-D), and mixed. This analysis focuses on IBS-D. Treatment options for IBS are limited, and only a few drugs have secured FDA approval for IBS-D. Current options include Sebela Pharmaceuticals’ Lotronex, Salix Pharmaceuticals’ Xifaxan, Allergan’s Viberzi, and off-label use of antidepressants, motor stimulants, and anticholinergic agents.
