Diabetic neuropathic pain is generally considered to be one of the most troublesome complications affecting diabetic patients and current therapy provides inadequate pain relief. In the present study, the effect of adenosine was investigated in a model of diabetic neuropathic pain. Diabetes was induced by streptozotocin (65 mg/kg, ip) in male Sprague Dawley rats and subjected to thermal (cold and hot) and chemical (formalin) stimuli. Diabetic rats developed hyperalgesia by the end of six weeks in thermal and chemical stimuli test. Adenosine (100, 200 and 500 mg/kg, ip) produced significant reversal of responses to thermal and chemical stimuli in diabetic rats. 8-Cyclopentyl-1, 3-dipropylxanthine (DPCPX 1 mg/kg, ip), an adenosine A1-receptor antagonist, but not 3,7-dimethyl-1-propargylxanthine (DMPX 1 mg/kg, ip), an adenosine A2A-receptor antagonist, reversed the protective effect of adenosine. These results indicate that adenosine is an effective analgesics in a model of diabetic neuropathy, and the protection produced by adenosine is via stimulation of adenosine A1-receptors.
