Key terms

Plecanatide is the guanylate cyclase-C agonist in TRULANCE, a prescription treatment for adult chronic idiopathic constipation and constipation-predominant irritable bowel syndrome.

Plecanatide resembles the intestinal signaling peptide uroguanylin. It activates receptors on the bowel lining, increasing cyclic GMP and fluid secretion into the intestinal lumen. This can improve stool passage. The mechanism is local bowel signaling, and it should not be conflated with systemic regenerative effects or proof that underlying causes of constipation have resolved. Product label.

Evidence limits

How to read the evidence

The responder difference supports a benefit for some patients but also shows that most did not meet the full durable-response threshold. CIC and IBS-C have separate eligibility and outcome definitions. Comparisons with linaclotide require direct evidence; sharing a receptor does not establish identical benefit, safety, or pediatric authorization. Product-specific scope.
