Rimegepant

Rimegepant is an oral antagonist of the CGRP receptor developed by Biohaven Pharmaceuticals. It received FDA approval on February 27, 2020 for the acute treatment migraine headache, and was subsequently approved by the European Commission in April 2022 for both the treatment and prevention of migraines. While several parenteral antagonists of CGRP and its receptor have been approved for migraine therapy (e.g. erenumab, fremanezumab, galcanezumab), rimegepant and ubrogepant were the only CGRP antagonists that possessed oral bioavailability until the approval of atogepant in 2021. The current standard of migraine therapy involves abortive treatment with "triptans", such as sumatriptan, but these medications are contraindicated in patients with pre-existing cerebrovascular and cardiovascular disease due to their vasoconstrictive properties. Antagonism of the CGRP pathway has become an attractive target for migraine therapy as, unlike the triptans, oral CGRP antagonists have no observed vasoconstrictive properties and are therefore safer for use in patients with contraindications to standard therapy.

Rimegepant is indicated for the acute treatment of migraine with or without aura in adults. Rimegepant is also indicated for the prevention of episodic migraine in adults.
