[Reaction of blood sugar and serum insulin to intravenous longterm treatment with Actovegin. Clinical double-blind study (author's transl)].

In a randomised double-blind study involving 20 diabetics and 20 patients with normal carbohydrate metabolism, the influence of a 14 days' course of intravenous infusion of protein-free calf blood extract (0.5 ml Actovegin/kg/day) and equivalent amounts of physiological saline solution on blood sugar and serum insulin was investigated by the oral glucose tolerance test (100 g Dextro-OGTT). In diabetic carbohydrate metabolism Actovegin was shown to improve the glucose tolerance significantly without alteration of the serum insulin, thus possessing antidiabetogenic activities. With normal carbohydrate metabolism, however, the behaviour of blood sugar and serum insulim was not changed by Actovegin.
