OBJECTIVE: The objective is to review the pharmacology, efficacy, and safety of intranasal zavegepant in the acute treatment of migraine with or without aura.

DATA SOURCE: PubMed, Embase database, and were searched using the following terms: Zavzpret, Zavegepant, BHV-3500, and migraine.

STUDY SELECTION AND DATA EXTRACTION: Articles published in English from January 2013 to September 2023 related to pharmacology, safety, efficacy, and clinical trials were assessed.

DATA SYNTHESIS: In a phase 2/3 trial, zavegepant 10 and 20 mg were more effective than placebo on primary endpoints of freedom of pain (22.5%, 23.1%, and 15.5%, respectively), and freedom from most bothersome symptoms (MBSs) (41.9%, 47.9%, and 33.7%, respectively) 2 hours after treatment. The incidence of adverse effects for both doses was similar to placebo. In a phase 3 trial, zavegepant 10 mg was compared with placebo. Two hours after treatment, more patients in the zavegepant group achieved pain freedom (24% vs 15%) and relief from MBSs (40% vs 31%) compared with placebo. Common adverse events included dysgeusia (21% zavegepant vs 5% placebo) and nasal discomfort (5% zavegepant vs 1% placebo).

RELEVANCE TO PATIENT CARE AND CLINICAL PRACTICE IN COMPARISON WITH EXISTING DRUGS: Zavegepant is indicated for acute treatment of migraine with or without aura in adults. Zavegepant method of administration and prompt relief of migraine symptoms may be an attractive alternative to triptans for those in need of relief.

CONCLUSION: Zavegepant may be a convenient and useful acute treatment option for migraines with and without aura.
