Calcitonin Gene-Related Peptide Etiology of Migraine Headache (CGRP) Receptor Antagonists May be due to both vascular changes and neuronal etiology Vascular component - constriction of blood vessels followed by reflex dilation – Calcitonin gene-related peptide (CGRP) is a potent endogenous vasodilator the dilation is what leads to the headache and pain signal-enhancing neuromodulator Neuronal component – depressed neuronal activity spreads across the brain CGRP receptor is believed to be released during a migraine and transmits and the headache occurs due to an inflammatory response due to signals that can cause incapacitating pain compensatory over-activity in certain nerves leading to release of substance P By blocking the CGRP receptor, the drugs are thought to inhibit the effect of and other vasoactive substances the neuropeptide responsible for pain and sensitization associated with Genetic component – familial tendencies migraine Triggers Some of the agents in this class are for preventive treatment while there are Food triggers – cheese; wine; alcohol; chocolate; caffeine two that are approved for acute treatment of migraine Behavior triggers – stress; sleep deprivation or excess; skipped meals; hormonal Rimegepant (Nurtec ODT) changes Ubrogepant (Ubrelvy) Environmental triggers – glare or flickering lights; noise; odors; weather changes
