Unlike other antipsychotics, aripiprazole is a high-efficacy partial agonist of the postsynaptic 5-HT 2C receptor (intrinsic activity = 82%) this property may underlie the minimal weight gain seen in the course of therapy, however if used while taking antidepressants it will become a functional antagonist and increase weight gain.

The term neuroleptic is often used as a synonym for antipsychotic, even though – strictly speaking – the two terms are not interchangeable. Antipsychotic drugs are a subgroup of neuroleptic drugs, because the latter have a wider range of effects. [280] [281] Antipsychotics are a type of psychoactive or psychotropic medication. [282] [283]
Many people can eventually be restarted on a lower dose of antipsychotic. [2] [3] As of 2011, among those in psychiatric hospitals on antipsychotics about 15 per 100,000 are affected per year (0.015%). [1] In the second half of the 20th century rates were over 100 times higher at about 2% (2,000 per 100,000). [1]
Clozapine, sold under the brand name Clozaril among others, is a psychiatric medication and was the first atypical antipsychotic to be discovered. [6] It is primarily used 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.
Typical antipsychotics block the dopamine 2 receptor (D2) receptor, causing a tranquilizing effect. [5] It is thought that 60–80% of D2 receptors need to be occupied for antipsychotic effect. [5] For reference, the typical antipsychotic haloperidol tends to block about 80% of D2 receptors at doses ranging from 2 to 5 mg per day. [5]
Psychosis risk increases 81% on high-dose amphetamine For this study, researchers analyzed medical data from adults between the ages of 16 and 35 treated at Mass General Brigham between 2005 and 2019.
Therapeutic drug monitoring (TDM) is a branch of clinical chemistry and clinical pharmacology that specializes in the measurement of medication levels in blood. Its main focus is on drugs with a narrow therapeutic range , i.e. drugs that can easily be under- or overdosed. [ 1 ]
As haloperidol is a high-potency typical antipsychotic, it tends to produce significant extrapyramidal side effects. According to a 2013 meta-analysis of the comparative efficacy and tolerability of 15 antipsychotic drugs it was the most prone of the 15 for causing extrapyramidal side effects. [29]
