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, and mixed; however, prior to 2017, only two ICD-10 codes existed: IBS with diarrhea and IBS without diarrhea. For the purposes of this analysis, we focus on the IBS without diarrhea population, which includes IBS-constipation (IBS-C). Limited treatment options are available for IBS, and only a few drugs have secured an FDA approval for IBS-C. Current treatment options include antidepressants (off-label), motor stimulants (off-label), anticholinergic agents (off-label), guanylate cyclase-C agonists (Allergan’s Linzess and Synergy Pharmaceuticals’ Trulance), and bicyclic fatty acids (Takeda’s Amitiza), all of which are only moderately effective in treating the disease.
