Alpha2-adrenergic receptor agonists exert potent analgesic and sedative/hypnotic effects. In addition, they have been shown to be neuroprotective in various experimental models, but the molecular pathways leading to these actions are still poorly defined. This review summarizes the available literature and discusses potential mechanisms of alpha2-adrenergic receptor agonist mediated neuroprotection.
