Cosyntropin (Cortrosyn) vs Synthetic Secretin (ChiRhoStim)
An educational, source-based comparison of Cosyntropin (Cortrosyn) and Synthetic Secretin (ChiRhoStim) — how each peptide works, what it's researched for, and what to know before going deeper.
Synthetic peptide containing the first 24 amino acids of ACTH — retains full corticotropic activity. Stimulates adrenal cortisol release for diagnostic testing.
- Primary and secondary adrenal insufficiency diagnosis
- • FDA-approved.
- • Single diagnostic dose; very well tolerated.
27-amino-acid peptide used to stimulate pancreatic secretions for diagnosis.
Synthetic human secretin that stimulates pancreatic bicarbonate, fluid secretion, and gastrin release — used diagnostically for pancreatic function, gastrinoma evaluation, and ERCP facilitation.
- Pancreatic function testing
- Gastrinoma (Zollinger-Ellison) diagnosis
- ERCP facilitation
- • FDA-approved.
- • Single diagnostic dose; minimal adverse effects.
