Which antipsychotic medication is known for being a phenothiazine?

Chlorpromazine is known for being a phenothiazine, which is a class of antipsychotic medications that primarily work by blocking dopamine receptors in the brain. This group was among the first medications developed for treating psychotic disorders such as schizophrenia. Chlorpromazine specifically has a long history of use and has been pivotal in the management of severe mental health symptoms, making it a notable representative of the phenothiazine class.

In contrast, the other listed medications belong to different classes of antipsychotics. Haloperidol, for example, is a butyrophenone and is not classified as a phenothiazine. Quetiapine and Olanzapine are both atypical antipsychotics, which target a wider range of neurotransmitter receptors and tend to have different side effects and efficacy profiles compared to phenothiazines. This distinction highlights the unique role of phenothiazines, like Chlorpromazine, within psychopharmacology.
