Which of the following is NOT an example of atypical antipsychotics?

Clozapine, Olanzapine, and Aripiprazole are all classified as atypical antipsychotics, which are known for their broader spectrum of treatment effects and different side effect profiles compared to typical antipsychotics. Atypical antipsychotics generally target both positive and negative symptoms of schizophrenia and have a lower risk of extrapyramidal symptoms.

Haloperidol is a typical antipsychotic, primarily used to treat acute psychotic episodes and has more frequent side effects related to movement disorders due to its dopamine antagonism. This makes it distinct from atypical antipsychotics, which are designed to minimize such side effects while effectively managing symptoms. Therefore, identifying Haloperidol as the odd one out in this context underscores the distinction between these two classes of medications in terms of mechanisms and effects.
