Research Overview
Linaclotide
Linaclotide has extensive clinical evidence for chronic idiopathic constipation and IBS-C, with consistent effects on stool frequency and abdominal symptom relief. Its mechanism is local GC-C activation in the gut with minimal systemic exposure.
Plecanatide
Clinical trials show plecanatide improves constipation outcomes with a generally favorable tolerability profile. Like linaclotide, it acts locally in the intestinal lumen via GC-C signaling rather than systemic hormone effects.
