Research Overview
Motilin
Motilin is a 22-amino-acid peptide released from the upper small intestine and is one of the classic physiologic prokinetic signals. It is a real peptide target for GI motility research, though not commonly used as a standard drug.
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.
