Which drug class is used to treat psychotic disorders?

• A. Antipsychotic
• B. Anti-impotence
• C. Anti-infective
• D. Antimigraine

Answer: (A)

Antipsychotics are the drug class used to treat psychotic disorders. They primarily block dopamine D2 receptors in brain pathways involved in thought and mood regulation, especially the mesolimbic pathway, which helps reduce core psychotic symptoms like delusions and hallucinations. There are typical antipsychotics, which can cause movement-related side effects, and atypical antipsychotics, which may have metabolic effects but often have fewer motor symptoms. The other options target different conditions—for example, anti-impotence drugs treat erectile dysfunction, anti-infectives treat infections, and anti-migraine drugs treat migraines—so they don’t address psychosis.
