Chronic idiopathic constipation and irritable bowel syndrome with constipation are commonly encountered in ambulatory patients, but limited options exist for patients with persistent or severe symptoms following treatment with nonprescription products. Plecanatide (Trulance, Synergy Pharmaceuticals, New York, NY) is a 16-amino acid peptide analog of uroguanylin that stimulates guanylate cyclase-C receptors to increase chloride and bicarbonate secretion into the intestine and prevents the absorption of sodium ions, thereby increasing the secretion of water into the lumen. The influx of additional fluid accelerates intestinal transit, softens the stool, and facilitates easier defecation. Plecanatide is the second guanylate cyclase-C receptor agonist to be approved by the US Food and Drug Administration for chronic idiopathic constipation and irritable bowel syndrome, but plecanatide is unique because its effects are limited to the proximal small bowel.
