The drug classes of typical antipsychotics and atypical antipsychotics are used to treat psychotic disorders. The most famous examples are Thorazine, Clozaril (typical antipsychotics), Abilify, Zyprexa, and Risperdal (atypical antipsychotics).

Haldol's drug classification is as a first-generation antipsychotic, also known as a typical antipsychotic. It works by blocking certain receptors in the brain, specifically dopamine receptors, to help manage symptoms of psychosis and other mental health conditions.

Typical antipsychotic drugs primarily block dopamine receptors in the brain, while atypical antipsychotic drugs affect multiple neurotransmitters, including serotonin and dopamine. Atypical antipsychotics are less likely to cause motor side effects like tremors and muscle stiffness compared to typical antipsychotics. However, atypical antipsychotics may have a higher risk of metabolic side effects such as weight gain and diabetes.

No, it is an antipsychotic but can produce sedation similar to that of barbituates.
