• While research into the exact mechanism that causes migraine is ongoing, CGRP is known to play a role in migraine pain2
  • CGRP acts at multiple sites along the trigeminovascular pathway, causing vasodilation, inflammation, and pain3

CGRP=calcitonin gene-related peptide.

UBRELVY is the first acute treatment for migraine that directly blocks CGRP5-7

CGRP plays a key role in migraine attacks, binding to CGRP receptors to cause pain, inflammation, and vasodilation1,2,8,9

Watch the UBRELVY mechanism of action

UBRELVY works differently than older acute migraine treatments—see how each works against migraine2,5,8

MIGRAINE PATHOPHYSIOLOGY CGRP is released, causing meningeal vessel expansion and pain signaling1,2,9

UBRELVY Targets the CGRP receptor itself, blocking CGRP from attaching5

TRIPTANS 5HT1B/1D agonists that constrict blood vessels and prevent release of neuropeptides; those already released continue to circulate1-3,9

BARBITURATES This class of drug acts by potentiating GABA-induced increases in chloride conductance. They enhance GABA binding to GABA A receptors10

NSAIDs The main effect of nonsteroidal anti-inflammatory drugs is the blockade of cyclooxygenase (COX) receptors11

Pharmacokinetic profile5

Within 11 minutes:
time to reach pharmacologically available concentration12*
12 hours:
active concentration is maintained6
1.5 hours:
time to peak plasma concentrations (Tmax)5
5-7 hours:
elimination half-life5

The clinical significance of these data is not known.

UBRELVY displays dose-proportional pharmacokinetics within the recommended dose range.5

*Based on the inhibition of human capsaicin-induced dermal vasodilation model, a pharmacodynamic measure of CGRP blockade, EC90=13 ng/mL.12
