Preliminary experience on treatment of insulin-dependent diabetes mellitus with a long-acting somatostatin analogue (L363,586).

L363,586 is a potent, long-acting, somatostatin derivative. Intravenous and intranasal administration to diabetic subjects was effective in reducing both fasting and postprandial hyperglycemia. Also in patients stabilized on a closed-loop insulin infusion device, the intranasal administration of L363,586 was able to improve the glucose imbalance known as dawn phenomenon. Therefore, this analogue associated to standard insulin replacement could be useful in the control of unstable diabetes.
