Indanorex (Dietor) is a stimulant drug. It has appetite suppressant effects. Indanorex caused no amelioration of reactive hypoglycemia. A significant increase in peak blood glucose was recorded after treatment. Insulin response to glucose peaked earlier after indanorex than metformin and was significantly higher. No significant changes were observed in plasma glucagon, cortisol, growth hormone and FFA responses to hypoglycemia after indanorex.
