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.
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.
