Antipsychotic

Aka: Antipsychotic, Anti-Psychotic, Neuroleptic
  1. See Also
    1. Extrapyramidal Side Effect
    2. Neuroleptic Malignant Syndrome
  2. Indications
    1. Psychosis (e.g. Schizophrenia)
  3. Efficacy: Newer low potency agents
    1. Atypicals only slightly better than high potency agents
      1. Similar efficacy in control of Psychosis
      2. Slightly less Extrapyramidal Side Effects (EPSE)
        1. Clozapine has much less EPSE, but has diabetes risk

      4. Compliance is similar for both types of agents
      5. Atypical Antipsychotics are much more expensive

Antipsychotic Agents (C0040615)

Definition (NCI) A type of drug used to treat symptoms of psychosis. 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.
Definition (MSH) Agents that control agitated psychotic behavior, alleviate acute psychotic states, reduce psychotic symptoms, and exert a quieting effect. They are used in SCHIZOPHRENIA; senile dementia; transient psychosis following surgery; or MYOCARDIAL INFARCTION; etc. These drugs are often referred to as neuroleptics alluding to the tendency to produce neurological side effects, but not all antipsychotics are likely to produce such effects. Many of these drugs may also be effective against nausea, emesis, and pruritus.
Definition (CSP) class of drugs used to treat symptoms of schizophrenia and other psychotic behavior; includes neuroleptics.
Definition (NCI) 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)
