Benperidol is a drug which is a highly potent butyrophenone derivative. It is the most potent neuroleptic on the European market, with chlorpromazine equivalency as high as 75 to 100 (about 150 to 200% potency in terms of dose compared to haloperidol).[1] It is an antipsychotic, which can be used for the treatment of schizophrenia,[2] but it is primarily used to control antisocial hypersexual behaviour,[3] and is sometimes prescribed to sex offenders as a condition of their parole, as an alternative to anti-androgen drugs such as cyproterone acetate.[4]

Benperidol was discovered at Janssen Pharmaceutica in 1961.
