Which of the following is a typical antipsychotic used to treat schizophrenia?

Haloperidol is considered a typical antipsychotic and is widely used in the treatment of schizophrenia. Typical antipsychotics primarily work by blocking dopamine receptors, which helps to manage the symptoms of schizophrenia, including delusions and hallucinations. Haloperidol has a long history of use in psychiatric practice and is effective in stabilizing acute psychotic episodes.

In comparisons with the other options, Fluoxetine and Sertraline are classified as selective serotonin reuptake inhibitors (SSRIs) and are primarily prescribed for depression and anxiety disorders rather than schizophrenia. Lithium is commonly used to stabilize mood in bipolar disorder but is not used as a first-line treatment for schizophrenia. Therefore, Haloperidol stands out as the appropriate choice among the listed options for treating schizophrenia.
