Function of Somatostatin Acetate
Somatostatin Acetate is a peptide hormone that regulates the endocrine system and affects neurotransmission and cell proliferation through its interaction with G protein.
① It can inhibit the secretion of growth hormone, thyroid stimulating hormone, insulin and glucagon.
②It can inhibit the secretion of gastric acid stimulated by the test meal and 5-peptide gastrin, and can inhibit the release of pepsin and gastrin.
③It can significantly reduce visceral blood flow, reduce portal vein pressure, reduce blood flow and pressure of collateral circulation, and reduce liver blood flow.
④Reduce the secretion of the pancreas and the secretion of the small intestine and gallbladder, reduce enzyme activity, and have a protective effect on pancreatic cells.
⑤ It can affect the absorption and nutritional function of the gastrointestinal tract.
Application of Somatostatin Acetate
Somatostatin Acetate can be used for severe and acute gastric and duodenal ulcer bleeding; acute erosive or hemorrhagic gastritis severe and acute bleeding; prevention of post-pancreatic complications after pancreatic surgery; inhibition of pancreas and Adjuvant treatment for severe secretion of leaky duct after upper small intestine surgery; regulating human differentiated gastric cancer cell lines
