Abstract
The efficacy of daily intramuscular injection of mixed gangliosides (Cronassial) for highly symptomatic diabetic neuropathy was investigated in a randomized double‐blind trial. There were 37 patients treated with 40 mg of gangliosides or placebo for 12 weeks and studied with physical examination, symptom scales, and electrophysiologic parameters. There was no demonstrated benefit of therapy. Given the spontaneous variation in the measurements employed, larger numbers of patients would have been needed to identify a significant change of 10% owing to therapy.
