HOW DO CGRP RECEPTOR ANTAGONISTS WORK?
Calcitonin gene-related peptide (CGRP) receptor antagonists are drugs used for preventing episodic migraines.
CGRP is a protein that is released around the brain. When released in excess, CGRP causes intense inflammation in the coverings of the brain (meninges). Excess CGRP release in the brain aggravates the pain of a migraine attack.
CGRP receptor antagonists work as an antagonist to CGRP receptors. They bind to CGRP receptors and do not allow the binding of CGRP.
HOW ARE CGRP RECEPTOR ANTAGONISTS USED?
CGRP receptor antagonists are given via the intravenous route for preventive treatment of migraines.
