An educational, source-based comparison of Plecanatide (Trulance) and Synthetic Secretin (ChiRhoStim) — how each peptide works, what it's researched for, and what to know before going deeper.

GC-C Agonist · Gastrointestinal
Plecanatide (Trulance)

Uroguanylin analog for chronic constipation.

Mechanism

Synthetic analog of human uroguanylin that activates guanylate cyclase-C in a pH-dependent manner, increasing intestinal fluid secretion and transit.

Research areas
  • Chronic idiopathic constipation
  • IBS-C
Considerations
  • FDA-approved.
  • Diarrhea most common adverse event.

Diagnostic · Gastroenterology
Synthetic Secretin (ChiRhoStim)

27-amino-acid peptide used to stimulate pancreatic secretions for diagnosis.

Mechanism

Synthetic human secretin that stimulates pancreatic bicarbonate, fluid secretion, and gastrin release — used diagnostically for pancreatic function, gastrinoma evaluation, and ERCP facilitation.

Research areas
  • Pancreatic function testing
  • Gastrinoma (Zollinger-Ellison) diagnosis
  • ERCP facilitation
Considerations
  • FDA-approved.
  • Single diagnostic dose; minimal adverse effects.
