Podcast 883: Migraine Treatment in Cardiovascular Disease

Contributor: Jorge Chalit, OMS II

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
