Abstract
Cannabinoid receptor agonists significantly diminish pain responses in animal models; however, they exhibit only modest analgesic effects in humans. The relative lack of efficacy in man may be because of the dose limitations imposed by psychoactive side effects. Cannabinoid agonists that selectively target CB(2) (peripheral) cannabinoid receptors should be free of psychoactive effects, perhaps allowing for more effective dosing. CB(2) receptor activation inhibits acute, inflammatory and neuropathic pain responses in animal models. In preclinical studies, CB(2) receptor agonists do not produce central nervous system effects. Therefore, they show promise for the treatment of acute and chronic pain without psychoactive effects.
