Emgality works by targeting and blocking a protein called calcitonin gene-related peptide (CGRP), which is released by nerves during migraines or cluster headaches and causes blood vessels in the brain to swell. By blocking CGRP, Emgality reduces the frequency and severity of migraines. Blocking CGRP is valuable because it addresses the root cause of migraine pain, rather than just treating symptoms.
