Which drug is not listed among the antipsychotics in the material?

• A. Chlorpromazine
• B. Clozapine
• C. Haloperidol
• D. Trifluoperazine

Answer: (C)

The point being tested is recognizing which drugs are included in the material’s example list of antipsychotics. In this set, chlorpromazine and trifluoperazine are both phenothiazines, while clozapine is an atypical antipsychotic. Haloperidol, however, belongs to a different chemical class called butyrophenones and is not part of the list shown in the material. The material often selects representative drugs from certain groups to illustrate concepts, so haloperidol can be the one not listed even though it is an antipsychotic in general.
