is a digestive tract hormone produced by the duodenum and the upper jejunum, secreted by the S cells, soluble in water, molecular weight 3056. Mainly by the kidney clearance, Half-Life is short, 2. 39min. The main factor promoting the release of secretin is gastric acid, and the pH in the duodenum or jejunum is <4.5.
Stimulates the release of secretin. The secretion of secretin is also increased after a meal. Somatostatin and enkephalin can inhibit the release. This product is a linear 27 peptide. It stimulates pancreatic acinar cells to secrete water and bicarbonate. Alkalization of the duodenum facilitates enzyme reaction, inhibits gastric acid secretion and stimulates insulin secretion; It enhances cholecystokinin (CCK) secretagogue; Inhibits postprandial gastrin secretion, and reduces gastric acid, stimulate the secretion of pepsin, inhibit pentagastrin to stimulate the secretion of human gastric acid; And promote bile excretion; Inhibit the contraction of gastrointestinal smooth muscle, reduce the tension of lower esophageal sphincter, but increase the tension of pyloric sphincter, inhibits gastric emptying, increases the effect of CCK on the contraction of the gallbladder.
occasional allergic reaction. High dose visible Diarrhea. Acute pancreatitis, allergic asthma and allergic history of patients with caution.
