Abstract: | Migraine associated with asthma or symptomatic orthostatic hypotension is a particularly difficult subgroup to manage. Metoclopramide is a useful pharmacological agent for orthostatic hypotension. I present the case report of a migraine patient with asthma and recurrent hypotensive syncope. Metoclopramide relieved recurrent syncope as well as migraine attacks in this patient. Metoclopramide has a striking influence on arginine vasopressin (AVP) secretion. AVP promotes antinociception and influences vasomotor and behavior control, which actions possibly keep migraine in remission. Further studies are necessary to confirm the migraine prophylactic value of metoclopramide. |
