Calcitonin Gene Related Peptide (CGRP) stands for calcitonin gene-related peptide, and it is a protein that is released around the brain. When CGRP is released, it causes intense inflammation in the coverings of the brain (the meninges), and for most migraine patients, causes the pain of a migraine attack. In fact, if you give CGRP by an intravenous method to a person with migraine, within four hours, most of them will get a migraine. That’s the basis of all the new treatments.
