Future medical prospects for Sandostatin.

Because of its widespread distribution within the nervous system and the gastro-enteropancreatic (GEP) system and its diverse physiological inhibitory actions on various gastrointestinal functions, including endocrine and exocrine secretion, motility, liver and splanchnic blood flow and absorption, native somatostatin has been viewed as a possible therapy for many diseases. However, its short duration of action and consequent limited clinical usefulness have been overcome with the availability of Sandostatin, a long-acting, synthetic octapeptide analogue of the naturally occurring hormone. Sandostatin represents a significant advance in the treatment of GH and TSH secreting pituitary tumours and GEP endocrine tumours (carcinoid tumour, VIPoma, glucagonoma, insulinoma, and gastrinoma). Preclinical in vitro and animal studies have shown the antineoplastic activity of the compound. Moreover, because of a possible direct effect on somatostatin receptor-positive endocrine tumour cells and indirect effect whereby Sandostatin lowers GH, IGF-1 and numerous gastrointestinal peptides, Sandostatin may prove useful as an adjunctive therapy in cancer patients. In vivo labelling of somatostatin receptor-positive tumours with radiolabelled somatostatin analogues now allows localisation of such tumours and their metastases. Moreover, targeted irradiation of these tumours by beta particle emitting isotopes attached to such somatostatin analogues may become possible. The use of Sandostatin in acute oesophageal variceal bleeding, pancreatic pseudocysts, gastrointestinal and pancreatic external fistulae, short bowel syndrome, dumping syndrome and AIDS-related refractory hypersecretory diarrhea has provided encouraging results. Preliminary reports indicate efficacy of Sandostatin in psoriasis, autonomic neuropathy (postprandial and orthostatic hypotension) and its ability to reduce height velocity in tall adolescents. The ultimate role of Sandostatin as a therapeutic agent in these disorders is being explored in prospective clinical trials.(ABSTRACT TRUNCATED AT 250 WORDS)[1]
