Abstract
BACKGROUND
Despite high prevalence of diabetic peripheral neuropathy there is no definite treatment for the condition. The present study was conducted to assess the efficacy of transdermal nitroglycerin patch in pain control of patients with DPN.
METHODS
This randomized, double-blind, crossover study was conducted on 30 patients with symmetric distal peripheral neuropathy and good glycemic control. The patients were randomly assigned to receive nitroglycerin transdermal and placebo patches in two 4-week stages. The severity of pain and other neuropathic sensory symptoms were assessed at the end of each course.
RESULTS
Mean reduction of pain severity was more prominent in the NTG group compared to placebo group of the study (p = 0.048) at least during the first phase of the study. Except for mood and sleep, a significant reduction in all Brief Pain Inventory scores was noted in the drug group (all corrected p < 0.05). SF-MPQ also showed the drug patch to be effective in improving different aspects of pain measured using McGill Pain Questionnaire, except for Role-emotional.
CONCLUSIONS
It could be concluded that nitroglycerin plasters can effectively help alleviate pain in patients with diabetic neuropathy.
