Mechanism can be effective
Calcitonin Gene-Related Peptide (CGRP) inhibition lowers trigeminal nerve sensitivity & inflammation
Vasoactive Intestinal Polypeptide (VIP) inhibition reduces vasodilation
Mechanism can be safe in cardiovascular risk patients
No vasoconstrictive properties
Triptans, which also lower CGRP and VIP, are vasoconstrictive
