Which drug is categorized as an antipsychotic and is used for treating schizophrenia?

Aripiprazole is categorized as an antipsychotic medication, specifically classified as a second-generation atypical antipsychotic. It is primarily used in the treatment of schizophrenia, a serious mental health condition characterized by disturbances in thought, perception, and behavior. Aripiprazole works by modulating the activity of neurotransmitters in the brain, particularly dopamine and serotonin, which can help alleviate the symptoms of schizophrenia.

The other options do not belong to the antipsychotic class. Lisinopril is an ACE inhibitor used to treat high blood pressure and heart failure. Venlafaxine Hydrochloride is an antidepressant that primarily addresses major depressive disorder, anxiety, and panic disorders, rather than psychotic disorders. Fluticasone is a corticosteroid used to treat conditions like asthma and allergic rhinitis. Thus, Aripiprazole is distinctly identified within the context of treating schizophrenia, marking it as the appropriate answer.
