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]

High-potency antipsychotics such as haloperidol, in general, have doses of a few milligrams and cause less sleepiness and calming effects than low-potency antipsychotics such as chlorpromazine and thioridazine, which have dosages of several hundred milligrams. The latter have a greater degree of anticholinergic and antihistaminergic activity ...
However, a high proportion of studies of risperidone were undertaken by its manufacturer, Janssen-Cilag, and should be interpreted with this in mind. [9] In those on antipsychotics, continued use decreases the risk of relapse. [10] [11] There is little evidence regarding consistent benefits from their use beyond two or three years. [11]
The antipsychotic quetiapine is typically dosed two to three times daily for the management of schizophrenia. [3] A simpler regimen would be a once daily administered antipsychotic. [1] For example, risperidone can be administered once daily. [4] A lack of adherence can lead to poor health outcomes, as well as unnecessary financial burden. [5]
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]

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 ...
