Zavegepant nasal spray (Zavzpret) was just approved by the FDA for the acute treatment of migraines. It belongs to the family of gepants. These drugs abort migraine attacks by blocking the CGRP receptor. CGRP (calcitonin gene-related peptide) is released during a migraine attack. Blocking this molecule or the receptor it attaches to relieves migraines in about 50% of people.
There are four CGRP monoclonal antibodies, or mAbs, that are injected once every one or three months to prevent migraine attacks. Gepants are taken by mouth. Two of them – ubrogepant (Ubrelvy) and rimegepant (Nurtec) – are approved for the acute treatment of migraine attacks. Rimegepant, along with atogepant (Qulipta), is also approved for the prevention of migraines.
Nasal sprays to treat migraines have the advantage of faster onset of action. They are particularly useful for people who have nausea or vomiting and have difficulty absorbing or holding down oral medications. Other migraine drugs in a nasal spray include sumatriptan, zolmitriptan, dihydroergotamine, and ketorolac. For patients for whom these older drugs are ineffective, cause side effects, or are contraindicated, zavegepant could be a very good option.
If there are no contraindications for the use of a triptan (e.g. heart or other vascular diseases), I would use sumatriptan first because of the cost. It is also likely that insurance companies will require that the patient fails sumatriptan before they agree to pay for a new and more expensive drug. This is what they usually require before paying for oral gepants.
Here is a list of what I consider to be the top 10 acute medications to treat migraine from the second edition of my book, The End of Migraines: 150 Ways to Stop Your Pain. I might add zavegepant to the next edition of this book.
- Sumatriptan
- Rizatriptan
- Eletriptan
- Naratriptan
- Zolmitriptan
- Rimegepant
- Ubrogepant
- Aspirin/caffeine/acetaminophen
- Naproxen
- Ibuprofen
