All butyrophenones and those phenothiazines that have a great affinity for D2 receptors are potent

Question

Quizplus · Accepted Answer

Butyrophenones and certain phenothiazines with high affinity for D2 receptors are commonly used as neuroleptics, also known as antipsychotics. They are used to treat severe mental disorders such as schizophrenia, mania, and delusions. Barbiturates are a class of sedatives, not antipsychotics. Antidepressants and anxiolytics are also not antipsychotic medications, although certain antidepressants may be used off-label for the treatment of psychosis in some cases.
