Taking a high dose of ADHD drugs is linked to more than five times greater risk of developing psychosis or mania, according to a new study published Thursday in the American Journal of Psychiatry.
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 ...
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]
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]
