Since octreotide resembles somatostatin in physiological activities, it can: 1  inhibit secretion of many hormones, such as gastrin, cholecystokinin, glucagon, growth hormone, insulin, secretin, pancreatic polypeptide, TSH, and vasoactive intestinal peptide,  reduce secretion of fluids by the intestine and pancreas,
Its basic sequence is glutamic acid-histidine-proline, although both ends of the peptide are modified. Secretion of thyroid-releasing hormone, and hence, TSH, is inhibited by high blood levels of thyroid hormones in a classical negative feedback loop.Additional information about TSH and its effects and control are presented in the section on the thyroid gland.ts basic sequence is glutamic acid-histidine-proline, although both ends of the peptide are modified. Secretion of thyroid-releasing hormone, and hence, TSH, is inhibited by high blood levels of thyroid hormones in a classical negative feedback loop.
