Icatibant (Firazyr) vs Synthetic Secretin (ChiRhoStim)
An educational, source-based comparison of Icatibant (Firazyr) and Synthetic Secretin (ChiRhoStim) — how each peptide works, what it's researched for, and what to know before going deeper.
Bradykinin B2 receptor antagonist for hereditary angioedema attacks.
Synthetic decapeptide that competitively blocks the bradykinin B2 receptor, halting the vascular leak that drives HAE swelling attacks.
- Hereditary angioedema (acute attacks)
- • FDA-approved.
- • Injection-site reactions very common.
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.
