What is Zavzpret?

Zavzpret (zavegepant) is a calcitonin gene-related peptide (CGRP) receptor antagonist nasal spray used to treat acute migraine in adults. Zavzpret can begin relieving pain as early as 15 minutes, and after 2 hours, Zavzpret is significantly better than a placebo at relieving nausea, sensitivity to light (photophobia) or sensitivity to sound (phonophobia).

Zavzpret is not used for preventing migraines.

How does Zavzpret work?

CGRP is a chemical messenger that has a role in causing pain and other symptoms of migraines. Zavzpret is a small molecule CGRP receptor antagonist that works by blocking the CGRP receptors, which reduces migraine pain and other symptoms of migraine, including nausea and sensitivity to light and sound.
