The atypical antipsychotics (AAP), also known as second generation antipsychotics (SGAs) and serotonin–dopamine antagonists (SDAs), [1] [2] are a group of antipsychotic drugs (antipsychotic drugs in general are also known as tranquilizers and neuroleptics, although the latter is usually reserved for the typical antipsychotics) largely introduced after the 1970s and used to treat psychiatric ...
On average, people receiving quetiapine scored lower (better) than people treated with typical antipsychotic drugs. There was a clear difference between the groups. This finding is based on data of moderate quality. MD 16.20 lower (23.34 to 9.07 lower)* Moderate *The meaning of these findings for day-to-day care is not clear
Clozapine, sold under the brand name Clozaril among others, is a psychiatric medication and was the first atypical antipsychotic to be discovered. [7] It is used primarily to treat people with schizophrenia and schizoaffective disorder who have had an inadequate response to two other antipsychotics, or who have been unable to tolerate other drugs due to extrapyramidal side effects.
Find out what typical and atypical antipsychotics are, what they are used for, how they work, and their potential risks and benefits.
Some adverse effects can be treated symptomatically by using adjunct medications such as anticholinergics (antimuscarinics). Some rebound or withdrawal adverse effects, such as the possibility of a sudden or severe emergence or re-emergence of psychosis in antipsychotic withdrawal, may appear when the drugs are discontinued, or discontinued too ...
No other atypical studied (risperidone, quetiapine, and ziprasidone) did better than the first-generation antipsychotic perphenazine on the measures used, nor did they produce fewer adverse effects than the typical antipsychotic perphenazine, although more patients discontinued perphenazine owing to extrapyramidal effects compared to the ...
Amisulpride is approved and used at low doses in the treatment of dysthymia and major depressive disorder. [10] [20] [11] [21] [22] [23] Whereas typical doses used in schizophrenia block postsynaptic dopamine D 2-like receptors and reduce dopaminergic neurotransmission, low doses of amisulpride preferentially block presynaptic dopamine D 2 and D 3 autoreceptors and thereby disinhibit dopamine ...
While atypical antipsychotics appear to have a lower rate of movement problems as compared to typical antipsychotics, risperidone has a high risk of movement problems among the atypicals. [46] [47] Atypical antipsychotics, however, are associated with a greater amount of weight gain and other metabolic side effects. [48] [47]
