Medication overuse could increase the cerebral cortex and trigeminal neuronal excitability, which would make migraine brain easy to suffer from cortical depression and generate central and peripheral sensitization by the trigeminal system.[29] A previous study also confirmed the sensitization of the trigeminal nociceptive neurons[30] and pain facilitation of the trigeminal nociceptive systems[31] in MOH.
However, it remains unclear whether dexmedetomidine can inhibit the function of VGSCs in neurons of the trigeminal system. In the present study, we investigated whether the peripheral dexmedetomidine-induced analgesia in the orofacial area might, in part, arise from suppression of VGSC activation via binding to Gi/o protein-coupled [alpha]2-adrenoceptors in small-sized TG neurons.

The activation of trigeminal system and sensitization of trigeminal nucleus of the brainstem are considered to play an important role in migraine.
