CGRP receptor antagonists represent a novel class of drug candidates for the treatment of migraine and are the first new class for the treatment of migraine in over 25 years. CGRP receptor antagonists potentially offer an alternative to current agents, particularly for patients who have contraindications to the use of triptans, such as those with underlying cardiovascular diseases, or those who have an inadequate response to standard therapies.
