Cannabinoids blocks tactile allodynia in diabetic mice without attenuation of its antinociceptive effect.

“Diabetic neuropathic pain is one of the most commonly encountered neuropathic pain syndromes.

It is well known that diabetic animals are less sensitive to the analgesic effect of morphine, and opioids are found to be ineffective in the treatment of diabetic neuropathic pain.

Cannabinoids are promising drugs and they share a similar pharmacological properties with opioids.

It has been reported that cannabinoid analgesia remained intact and to be effective in some models of nerve injury.

Thus, we investigated antinociceptive efficacy and the effects of cannabinoids on behavioral sign of diabetic neuropathic pain in diabetic mice by using WIN 55, 212-2, a cannabinoid receptor agonist.

This study suggests that cannabinoids have a potential beneficial effect on experimental diabetic neuropathic pain.”
