Chirhostim (Secretin Human)

Chirhoclin · FDA-approved active Small molecule Quality 50/100

Chirhostim works by binding to the secretin receptor, mimicking the natural hormone secretin to stimulate pancreatic function.

Chirhostim (Secretin Human) is a small molecule hormone developed by CHIRHOCLIN, targeting the secretin receptor. It is classified as a secretin-class hormone and was FDA-approved in 2002 for Secretin Stimulation Testing. As a patented product, its commercial status is proprietary. Key safety considerations include its half-life of 2.41 hours. Chirhostim is used to diagnose pancreatic function.

Mechanism of action

Mechanism of Action. 12.1 Mechanism of ActionThe primary action of ChiRhoStim (R) is to stimulate pancreatic ductal cells to secrete pancreas fluid in large volumes that contain bicarbonate. Secretin is hormone that is normally released from the duodenum upon exposure of the proximal intestinal lumen to gastric acid, fatty acids and amino acids. Secretin is released from enterochromaffin cells in the intestinal mucosa. Secretin receptors have been identified in the pancreas, stomach, liver, colon and other tissues. When secretin binds to secretin receptors on pancreatic duct cells it opens cystic fibrosis transmembrane conductance regulator (CFTR) channels, leading to secretion of bicarbonate-rich-pancreatic fluid. Secretin may also work through vagal-vagal neural pathways since stimulation of the efferent vagus nerve stimulates bicarbonate secretion and atropine blocks secretin-stimulated pancreatic secretion.
