Mechanism of action

CGRP is released during migraine attacks and contributes to pain signaling and neuroinflammation. By binding to and neutralizing CGRP, fremanezumab prevents its interaction with CGRP receptors on sensory neurons, thereby reducing migraine frequency and severity. This mechanism has been shown to be effective in both episodic and chronic migraine prevention.
