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.
