The effect of a long-acting somatostatin analogue (SMS 201-995) on intermediary metabolism and gut hormones after a test meal in normal subjects.
2007
SUMMARY
SMS 201–995 is an octapeptide analogue of somatostatin. The effect of a single subcutaneous (s.c.) injection of 50 μg SMS 201–995 on postprandial intermediary metabolism was investigated in normal subjects. In spite of a long-lasting post-prandial suppression of insulin secretion, there were no significant changes in the plasma concentration of alanine, glycerol, 3-OH-butyrate or lactate. However, SMS 201–995 impairs carbohydrate tolerance, probably due to inhibition of insulin secretion. Basal and post-prandial plasma concentrations of the gut regulatory peptides pancreatic glucagon, motilin, pancreatic polypeptide, gastric inhibitory polypeptide, enteroglucagon, gastrin and peptide YY were suppressed up to 5 hours after subcutaneous administration of a single dose of SMS 201–995.
