• 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

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

CGRP plays a key role in migraine attacks, binding to CGRP receptors to cause pain, inflammation, and vasodilation1,8-10

MIGRAINE PATHOPHYSIOLOGY CGRP is released, causing meningeal vessel expansion and pain signaling1,9,10

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 circulate1,3,9,10

BARBITURATES This class of drug acts by potentiating GABA-induced increase in chloride conductance. They enhance GABA binding to GABA A receptors11

NSAIDs The main effect of nonsteroidal anti-inflammatory drugs is the blockade of the enzyme cyclooxygenase (COX) receptors12

*CGRP=calcitonin gene-related peptide.

UBRELVY Pharmacokinetic profile

Within 11 minutes:
time to reach pharmacologically available concentration13†
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 near dose-proportional pharmacokinetics within the range of 40 to 400 mg.5

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