CGRP antagonists for decreasing migraine frequency: New options, long overdue

Abstract

The cornerstone of preventive migraine treatment has long been drugs developed for other diseases such as epilepsy, depression, and hypertension. But a new set of drugs is available for preventing migraine attacks: erenumab, galcanezumab, fremanezumab, and eptinezumab. These monoclonal antibodies target calcitonin gene-related peptide (CGRP) or its receptors, each a key molecule in the pathophysiology of migraine.
