Butyrophenone

Butyrophenone is synthetic agents containing the phenyl-1-butanone group, most Butyrophenones are neuroleptic (antipsychotic) drugs, such as haloperidol, droperidol, or azaperone, that control schizophrenic symptoms (hallucinations, delusions, dementia). Most antipsychotic agents interfere with neurotransmitter functions, usually blocking dopamine receptors, and induce behavioral, endocrine, motor-kinetic effects. (NCI04) — NCI Thesaurus (NCIt)
