Which of the following medications is classified as an antipsychotic?

The medication classified as an antipsychotic from the options provided is Zyprexa. Zyprexa, or olanzapine, is part of the atypical antipsychotics, which are used to treat conditions such as schizophrenia and bipolar disorder. This class of medications primarily works by affecting neurotransmitters in the brain, particularly dopamine and serotonin, to help stabilize mood and reduce symptoms of psychosis.

Geodon, known generically as ziprasidone, is also an atypical antipsychotic. This means it too is used to treat similar psychiatric conditions by modulating neurotransmitter activity. Therefore, in the context of your question, both Zyprexa and Geodon fit the classification of antipsychotic medications, highlighting their importance in psychiatric treatment.

On the other hand, Keflex is an antibiotic used to treat bacterial infections, and Levalbuterol Hydrochloride is a bronchodilator used for respiratory conditions such as asthma. Both of these medications do not fall under the category of antipsychotics as they serve entirely different purposes in medical treatment.
