All of the following are third generation antipsychotics except,
Correct answer
C
Rationale
The correct answer is C, haloperidol (Haldol), because it is a first-generation antipsychotic, not a third-generation one. Haloperidol primarily acts on dopamine receptors, unlike third-generation antipsychotics which target multiple neurotransmitter systems. Lurasidone, cariprazine, and aripiprazole are all third-generation antipsychotics with unique pharmacological profiles targeting serotonin and dopamine receptors. Therefore, haloperidol does not fit the criteria for a third-generation antipsychotic. Choices A, B, and D are incorrect because they are indeed third-generation antipsychotics with distinct mechanisms of action.
