Which of the following is a group of drugs used to treat psychosis?

Phenothiazines are a class of antipsychotic medications that are specifically used to treat psychosis, which includes conditions such as schizophrenia and severe mood disorders. These drugs work primarily by blocking dopamine receptors in the brain, which helps to reduce the symptoms of psychosis, such as hallucinations and delusions.

In contrast, antidepressants are primarily intended to treat mood disorders, particularly depression and some anxiety disorders, not psychosis. Selective reuptake inhibitors are a specific type of antidepressant that primarily targets serotonin reuptake to improve mood. Stimulants, on the other hand, are generally used to treat attention deficit hyperactivity disorder (ADHD) and narcolepsy and are not indicated for treating psychosis. Therefore, phenothiazines are the group of drugs specifically designed to address the symptoms of psychosis effectively.
