Direct Answer
Plecanatide (Trulance) is FDA-approved for chronic idiopathic constipation and IBS with constipation, with Phase 3 RCTs demonstrating consistent efficacy on validated endpoints. As a uroguanylin analog that works locally in the GI tract with minimal systemic absorption, it has an excellent safety profile. For guanylate cyclase-C agonist research and IBS-C/CIC treatment, it is a validated option alongside linaclotide.
