Purpose Of ReviewMigraine remains a challenging condition to treat, thus highlighting the need for a better understanding of its molecular mechanisms. This review intends to unravel a new emerging target in migraine pathophysiology, the adenosine 5'-triphosphate-sensitive K+ (KATP) channel.Recent FindingsKATP channel is a common denominator in the cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP) mediated intracellular cascades, both of which are involved in migraine. Intravenous infusion of KATP channel opener, levcromakalim, provoked migraine attack associated with dilation of extracerebral arteries in all persons with migraine. Preclinical and clinical studies implicate KATP channels in migraine initiation. KATP channel is a novel therapeutic target for the acute and preventive treatment of migraine. Future studies are warranted to provide a better understanding of the role of KATP channel subgroups in migraine.
