What are the uses of this medicine?

• Zavegepant (Zavzpret), is a prescription medicine used in adults for the acute treatment of migraine attacks with or without aura.

Limitations of use:

• Zavzpret is not used to prevent migraine attacks.

How does this medicine work?

• Zavegepant (Zavzpret), is a highly soluble small molecule calcitonin gene related peptide (CGRP) receptor antagonist, with potential analgesic and immunomodulating activities.
• Upon administration, zavegepant targets, binds to and inhibits the activity of CGRP receptors located on mast cells in the brain.
• This may inhibit neurogenic inflammation caused by trigeminal nerve release of CGRP.
• In addition, by blocking the CGRP receptors located in smooth muscle cells within vessel walls, zavegepant inhibits the pathologic dilation of intracranial arteries.
• Zavegepant, by blocking the CGRP receptors, also suppresses the transmission of pain by inhibiting the central relay of pain signals from the trigeminal nerve to the caudal trigeminal nucleus.
• Altogether, this may relieve migraine.
• As CGRP receptors induce the release of pro-inflammatory mediators, such as interleukin-6 (IL-6), from inflammatory cells, zavegepant may prevent an IL-6-mediated inflammatory response.
• Zavegepant may also inhibit the CGRP-mediated induction of eosinophil migration and the stimulation of beta-integrin-mediated T cell adhesion to fibronectin at the site of inflammation, and may abrogate the CGRP-mediated polarization of the T cell response towards the pro-inflammatory state characterized by Th17 and IL-17.
• This may improve lung inflammation and oxygenation, prevent edema, and further lung injury.
• CGRP, a 37 amino-acid peptide expressed in and released from a subset of polymodal primary sensory neurons of the trigeminal ganglion and nerve fibers projecting to the airways and by pulmonary neuroendocrine cells, plays an important role in pain transmission, inflammation, and neurogenic vasodilatation.
• It is released upon acute lung injury and upregulation of transient receptor potential (TRP) channels.
