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
