Butyrophenone

Butyrophenone is a chemical compound (a ketone); some of its derivatives (called commonly butyrophenones) are used to treat various psychiatric disorders such as schizophrenia, as well as acting as antiemetics.

Butyrophenones are a class of pharmaceutical drugs derived from butyrophenone.

Examples include:


 * Haloperidol, the most widely-used drug in this class
 * Droperidol, often used for neuroleptanalgesic anesthesia and sedation in intensive-care treatment
 * Benperidol, the most potent commonly-used antipsychotic (~ 200 times more potent as chlorpromazine)
 * Triperidol, a highly-potent antipsychotic (100 times more potent than chlorpromazine)
 * Melperone, a weakly-potent antipsychotic, in Europe commonly used for treatment of insomnia, confusional states, psychomotor agitation, and delirium, in particular, in geriatric patients
 * Lenperone
 * Domperidone, an dopamine-antagonist antiemetic, derived further from butyrophenone (not being a butyrophenone itself).

The atypical antipsychotic risperidone, although not a butyrophenone, was developed with the structures of benperidol and lenperone as a basis.
