UBRELVY® WORKS DIFFERENTLY
THAN TRIPTANS1-3

DURING A MIGRAINE ATTACK, CGRP IS RELEASED FROM ONE NEURON 
AND TRAVELS TO THE NEXT, SENDING OUT A PAIN SIGNAL1

UBRELVY works by blocking CGRP by binding to its receptor and providing migraine relief

UBRELVY directly blocks CGRP by binding to its receptor on the postsynaptic neuron, thereby blocking pain signaling.2,3

The clinical significance is not known.

UBRELVY IS NOT KNOWN TO CONSTRICT BLOOD VESSELS

WHEN ACTING ON THE MIGRAINE DISEASE PATHWAY.4

The clinical significance of this mechanism of action is unknown.

See Important Safety Information for Warnings and Precautions.

Triptans prevent CGRP from being released but do not stop already released CGRP

Triptans attach to serotonin receptors on presynaptic neurons. This prevents more CGRP from being released, but CGRP that has already been released continues to circulate—which could allow pain signaling to continue.2 Triptans are known to cause vasoconstriction when acting on the migraine disease pathway.1
