Revision as of 11:41, 30 September 2011
In medicine, antipsychotic agents "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."[1]
Antipsychotics effect may be by blocking dopamine receptors (D2).
Classification
The newer drugs are called either second generation or atypical antipsychotic agents. This group includes olanzapine (Zyprexa®), quetiapine (Seroquel®), risperidone (Risperdal®), aripiprazole (Abilify®), ziprasidone, clozapine, and amisulpride.[2] The atypical antipsychotics tend to also block serotonin receptors (5HT).[3]
The older drugs are called either first generation or typical antipsychotic agents. This group includes phenothiazine derivitives such as chlorpromazine, thiozanthene derivitives such as thiothixene, and butyrophenone derivitives such as haloperidol.[3]
Effectiveness
Delirium
Regarding the treatment of delirium, all drugs may have similar efficacy.[4]
Mania
Antipsychotic agents may be better than mood stabilizers (valproate, ziprasidone, topiramate, lamotrigine, and gabapentin) for treatment of acute mania.[5]
Schizophrenia
The second generation anti-psychotic agents amisulpride, clozapine, olanzapine, and risperidone may be the most effect agents for schizophrenia.[6]
Dementia
Regarding the treatment of dementia, a randomized controlled trial that compared the second generation anti-psychotic agents found that none improved functioning, care needs, or quality of life with statistical significance[2]; however, olanzapine and risperidone may reduce anger.[7]
Autism
Risperidone help in children with autism who have serious behavioral problems a randomized controlled trial.[8]
Adverse effects
Extrapyramidal effects
The second generation agents may cause less extrapyramidal effects[6] and quetiapine may cause the least effects among this group.[2] Haloperidol less than 3 mg day reduced adverse effects.[4]
Mortality
Short term increases in mortality may occur with haloperidol, olanzapine, and risperidone, but not quetiapine.[9] Antipsychotic agents may increase mortality in patients with dementia.[10]
Cardiovascular effects
A retrospective cohort study concluded "current users of typical and of atypical antipsychotic drugs had a similar, dose-related increased risk of sudden cardiac death."[11] Former users do not have increased risk.
A meta-analysis concluded "all antipsychotics are associated with an increased risk of stroke, and the risk might be higher in patients receiving atypical antipsychotic"."[12]
Prolongation of the QT interval may be the most with thioridazine and least with risperidone.[13]
Metabolic effects
The second generation agents may cause hyperglycemia and hyperlipidemia; patients should be tested for these prior to treatment.[14]
Other effects
Withdrawing psychotropics agents may prevent accidental falls.[15]
