This is a list of investigational headache and migraine drugs, or drugs that are currently under development for clinical use in the treatment of headaches and/or migraines but are not yet approved. They may also be referred to as investigational antimigraine agents.
Chemical/generic names are listed first, with developmental code names, synonyms, and brand names in parentheses. The format of list items is "Name (Synonyms) â Mechanism of Action â Indication [Reference]".
This list was last comprehensively updated in September 2025. It is likely to become outdated with time.
