[Clinical use of octreotide (Sandostatin) in endocrinology].

Abstract
Octreotide is a synthetic octapeptide somatostatin analogue which has higher potency and longer duration of action than the natural hormone. It is effective after subcutaneous administration and no rebound hypersecretion has been observed. Pharmacological effects of octreotide include inhibition of numerous hormones (growth hormone, TSH, insulin, glucagon and all gut hormones), of exocrine secretion (gastric acid, pancreatic enzyme), and of small-bowel absorption. This review deals with clinical application of octreotide in endocrine disorder. In patients with acromegaly octreotide treatment results in decrease of growth hormone (GH) and IGF-I together with tumour shrinkage and clinical improvement. Although variability in response to treatment is obvious for majority of patients the most effective dose is 100 mcg three times daily subcutaneously. Normalization of GH levels could be achieved in more than 50% of treated patients. It has also been shown that octreotide could be effective in TSH secreting pituitary adenoma, ACTH secreting adenoma as well as in non-secretory pituitary tumours. A marked biochemical and clinical responses together with longer survival have been reported in most of the patients with gastroenteropancreatic (GEP) tumours. Patients who benefit the most from octreotide therapy are those with carcionid syndrome (successful control of diarrhoea, flushing episodes and wheezing) and VIPomas (control of diarrhoea). In patients with insulin-dependent diabetes mellitus (IDDM) octreotide suppresses GH levels, postprandial blood glucose increases with resultant decrease in daily insulin requirements. In women with polycystic ovary syndrome (PCOS) octreotide has inhibitory effect on serum LH and ovarian androgens. This could have beneficial effect on ovulatory performance in women with PCOS.
