Abstract:
The effects of tryptamine on blood glucose levels were studied. Tryptamine induced significant hypoglycemia in mice. The hypoglycemia elicited by tryptamine was strongly antagonized by methysergide, an antagonist of both 5-HT1 and 5-HT2 receptors. A 5-HT2 receptor antagonist, ketanserin, partially inhibited the tryptamine-induced hypoglycemia. These results suggest that tryptamine-induced hypoglycemia is mediated by 5-HT1 and 5-HT2 receptors.
