This product is a synthetic octapeptide analog of somatostatin. It shares with native somatostatin the 4-peptide sequence required for activity as a promoter (benzene, chromogen, Lai, Su). However, because octreotide includes two D-amino acids and a deformed threonine, it is more resistant to degradation by plasma peptidases and has a longer half-life (about 30-fold) than growth inhibition. The pharmacological effects of this product is similar to that of natural somatostatin, which can inhibit serotonin, vasoactive intestinal peptide (VIP), insulin, glucagon, secretin, actin and pancreatic polypeptide. It is more selective than natural growth inhibition for inhibition of growth hormone secretion and less effective for insulin release. The effect of octreotide on susceptible target tissues may be mediated by its effect on the cell surface somatostatin receptor promoter. Half-Life of 1.5 h.
The side effects of this product are Abdominal Pain, abdominal distension, Diarrhea, steatorrhea; Gallstone formation; Glucose tolerance may decrease or worsen in the early stage of treatment, and then can be improved; Long-term application without endogenous antibody production, there was no obvious rebound or adverse reaction when the drug was stopped or rapidly reduced. 2~8 deg C for long-term storage.
