 | Hazard Information | Back Directory |  | [Uses] 
 Stimulates pancreatic and gastric secretions to aid in the diagnosis of pancreatic exocrine dysfunction and the diagnosis of gastrinoma.

 SecretinKabi (KabiVitrum, Sweden).
 |  | [General Description] 
 Secretin is a gastrointestinal hormone and a neuropeptide. It is synthesized from a precursor protein and shares sequence homology with other secretin family proteins like glucagon and vasoactive intestinal peptide (VIP).
 |  | [Biochem/physiol Actions] 
 Secretin regulates the secretion of gastric acid and pancreatic bicarbonates. It serves as an antidiuretic hormone in the neurohypophysial-renal axis and participates in osmoregulation. Secretin mediates its function through the G-protein coupled secretin receptors. It regulates the pH of the duodenal by modulating gastric acid secretion.
