(antipsychotic) A drug used to treat schizophrenia and other severe mental health disorders; relieves symptoms such as delusions and hallucinations.

These include hallucinations (sights, sounds, smells, tastes, or touches that a person believes to be real but are not real), delusions (false beliefs), and dementia (loss of the ability to think, remember, learn, make decisions, and solve problems). Most antipsychotic agents block the action of certain chemicals in the nervous system.

Also known as neuroleptics, major tranquilizers, or antischizophrenics, natural or synthetic. Antipsychotic Agents relieve and control the symptoms of schizophrenic illness (hallucinations, delusions, dementia). Most antipsychotic agents interfere with various neurotransmitter functions, often blocking dopamine receptors, and induce diverse behavioral, endocrine, motor-kinetic effects. (NCI04)

Many of these drugs may also be effective against nausea, emesis, and pruritus.

Antipsychotic drugs are divided into conventional antipsychotics and 2nd-generation antipsychotics (SGAs) based on their specific neurotransmitter receptor affinity and activity. SGAs may offer some advantages, both in terms of modestly greater efficacy (although recent evidence casts doubt on SGAs' advantage as a class) and reduced...
