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.
Secretin
Secretin is a classic GI hormone with extensive physiology literature and established diagnostic use. It remains important for studying pancreatic secretory function, biliary responses, and duodenal feedback.
