List of investigational antipsychotics

This is a dynamic list and may never be able to satisfy particular standards for completeness. You can help by adding missing items with reliable sources.

This is a list of investigational antipsychotics, or antipsychotics that are currently under development for clinical use but are not yet approved. Chemical/generic names are listed first, with developmental code names, synonyms, and brand names in parentheses.

This list was last comprehensively updated in December 2017. It is likely to become outdated with time.
