Treatment of Chronic Painful Diabetic Neuropathy With Isosorbide Dinitrate Spray

Abstract
OBJECTIVE—Considerable evidence implicates impaired nitric oxide (NO) generation in the pathogenesis of diabetic neuropathic pain. We therefore conducted a pilot study to examine the effects of isosorbide dinitrate (ISDN), a NO donor with local vasodilating properties, in spray form in the management of chronic neuropathic pain.
