High Quality Content by WIKIPEDIA articles! The atypical antipsychotics (also known as second generation antipsychotics) are a group of antipsychotic drugs used to treat psychiatric conditions. Some atypical antipsychotics are FDA approved for use in the treatment of schizophrenia. Some carry FDA approved indications for acute mania, bipolar mania, psychotic agitation, bipolar maintenance, and other indications.Atypicals are a group of unrelated drugs united by the fact that they work differently from typical antipsychotics. Most share a common attribute of working on serotonin receptors as well as dopamine receptors. One drug, amisulpride, does not have serotonergic activity. Instead it has some partial dopamine agonism. Another drug, aripiprazole, also displays some partial dopamine agonism, 5-HT1A partial agonism, and 5-HT2A antagonism.
