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.
- What patient shares do key therapies and brands garner by line of therapy in newly diagnosed IBS-D patients? What are the quarterly trends in prescribing among recently treated and newly diagnosed IBS-D patients?
- How have Xifaxan and Viberzi been integrated into the treatment algorithm, and what is their source of business?
- What percentage of IBS-D patients receive drug therapy within 365 days of diagnosis, and how quickly? What percentage of patients progress to later lines of therapy within 365 of diagnosis?
- What percentage of IBS-D patients are treated with monotherapy versus combination therapy? What are the most commonly used combinations? What are the product-level compliance and persistency rates among drug-treated patients?
