Educational Pearls:
-
Migraine pathophysiology
-
Primarily mediated through the trigeminovascular system
-
Serotonin, dopamine, and calcitonin gene-related peptide (CGRP)
-
Trigeminovascular system is linked to the trigeminal nucleus caudalis, which relays pain to the hypothalamus and cerebral cortex
-
-
One effective treatment for acute migraines is -triptan medications
-
5-HT1D/1B agonists such as sumatriptan
-
Often combined with NSAIDs and dopamine antagonists (as antiemetics) in migraine cocktails
-
-
Diphenhydramine (Benadryl) was shown to be ineffective in a randomized controlled trial comparing it with placebo and a dopamine antagonist antiemetic.
-
The -triptan medications carry significant risk for peripheral vasoconstriction and are therefore avoided in cardiovascular disease
-
One serotonin agonist specifically approved for use in vascular disease
-
Lasmiditan – 5-HT1F agonist
-
Slightly different mechanism of action avoids peripheral vasoconstriction
-
-
CGRP antagonists are also used in patients who are unresponsive to -triptans
