What are Gepants and How Do They Work?
Ubrelvy (ubrogepant) belongs to a class of medications called calcitonin gene-related peptide (CGRP) receptor antagonists, commonly referred to as "gepants". This class of drugs has revolutionized migraine treatment because they target the specific mechanism of a migraine attack without the cardiovascular risks associated with older medications like triptans.
CGRP is a protein naturally found in the nervous system, particularly in the trigeminal system, which is involved in migraine pain. During a migraine attack, the body releases an excess of CGRP, which can cause blood vessels in the brain to widen and trigger inflammation and pain signals. Gepants work by blocking the CGRP receptor, preventing CGRP from binding and activating this pain pathway. The result is a reduction in pain and associated symptoms like nausea and sensitivity to light and sound.
Comparing Ubrelvy to Other Gepants for Acute Treatment
While Ubrelvy is a highly effective option for acute migraine relief, it is not the only gepant on the market. Other FDA-approved gepants available for acute treatment include Nurtec ODT (rimegepant) and Zavzpret (zavegepant). Each has its own unique profile regarding administration, formulation, and indications.
Ubrelvy (ubrogepant) vs. Nurtec ODT (rimegepant)
Both Ubrelvy and Nurtec ODT are oral medications, but their formulation and approved uses differ.
- Formulation: Ubrelvy is a standard oral tablet that is swallowed whole. In contrast, Nurtec ODT is an orally disintegrating tablet (ODT) that dissolves on or under the tongue without the need for water. This can be a significant benefit for people who experience nausea or difficulty swallowing during a migraine attack.
- Indications: Ubrelvy is only approved for the acute treatment of migraines in adults. Nurtec ODT has a dual indication, meaning it can be used for both the acute treatment and the prevention of migraines.
- Administration: For acute treatment, Ubrelvy is typically taken as directed by a healthcare provider, with the possibility of a second dose if needed after a specific time interval. For Nurtec ODT, the acute use involves a single tablet.
Ubrelvy (ubrogepant) vs. Zavzpret (zavegepant)
Zavzpret (zavegepant) offers an alternative for those who prefer a non-oral option or need very rapid relief. Zavzpret is a nasal spray, while Ubrelvy is an oral tablet.
- Administration and Onset: The nasal spray delivery of Zavzpret may result in a faster onset of action for some patients compared to oral tablets like Ubrelvy. This is particularly useful for those whose migraines are accompanied by severe nausea or vomiting, as it bypasses the gastrointestinal tract.
- Indication: Zavzpret is also indicated for the acute treatment of migraines but is not approved for prevention.
- Common Side Effects: Zavzpret's administration method can lead to side effects like nasal discomfort and temporary taste changes, which are not seen with oral gepants.

| Repeat Dosing (Acute) | Yes (within 24 hours), if directed by healthcare provider | No | No (within 24 hours) |
| Administration Time | Taken as soon as migraine symptoms begin | Taken as soon as migraine symptoms begin | Taken as soon as migraine symptoms begin |
Understanding Triptans and Other Alternatives
For many years, triptans were a first-line treatment for acute migraines. Triptans work by constricting blood vessels in the brain and blocking pain pathways. However, this vasoconstrictive effect makes them unsuitable for patients with certain cardiovascular risk factors, such as uncontrolled hypertension or a history of stroke. Gepants, which do not cause vasoconstriction, are a valuable alternative for these individuals.
Another non-gepant oral alternative for acute treatment is Reyvow (lasmiditan), a serotonin agonist that also works differently from triptans but carries a risk of central nervous system side effects like dizziness and requires restrictions on driving. Some patients may also use over-the-counter pain relievers or other non-CGRP based prescription medications, but these are typically less effective for severe migraines.
Which Medication is Right for You?
Choosing the best medication depends on several individual factors, and consultation with a healthcare provider is essential.
- Administration Preference: Do you struggle with swallowing pills during a migraine? The ODT formulation of Nurtec or the nasal spray of Zavzpret might be a better fit.
- Acute vs. Preventive Needs: If you experience frequent migraines and are looking for a preventive medication that can also be used for acute attacks, Nurtec ODT is the only gepant with this dual indication.
- Side Effect Profile: While all gepants are generally well-tolerated, side effect profiles differ slightly. Some may experience more nausea with one drug than another, while Zavzpret carries unique side effects related to nasal administration.
- Drug Interactions: All gepants interact with certain medications that affect the CYP3A4 liver enzyme. Your doctor needs a complete list of your medications and supplements to avoid dangerous interactions.
- Cost and Insurance Coverage: Cost can be a significant factor, as gepants are brand-name medications and coverage varies by insurance plan. Pharmaceutical manufacturers often offer savings cards or patient assistance programs.

Conclusion
When considering what drug is comparable to Ubrelvy, several powerful alternatives within the gepant class are available. Nurtec ODT and Zavzpret Nasal Spray are both strong candidates for acute migraine treatment, each offering distinct advantages in formulation and delivery. The best choice is a personal one, made in consultation with a healthcare provider who can evaluate your medical history, frequency of attacks, and individual preferences. The development of these medications provides more options than ever before, moving migraine management away from a one-size-fits-all approach and towards personalized, targeted relief.
