Which listed drug is an antipsychotic commonly used to treat schizophrenia?

• A. Haldol
• B. Prozac
• C. Lithium
• D. Xanax

Answer: (A)

Antipsychotics work by blocking dopamine receptors in brain circuits that drive psychotic symptoms, helping to reduce delusions and hallucinations seen in schizophrenia. Haloperidol is a classic example of a typical antipsychotic and is commonly used to treat schizophrenia because it effectively blocks dopamine D2 receptors, especially in pathways tied to positive symptoms. The other options are not antipsychotics—Prozac is an SSRI antidepressant, Lithium is a mood stabilizer used in bipolar disorder, and Xanax is a benzodiazepine for anxiety.
