A 24-year-old male college student is brought to the emergency department by his parents due to bizarre behavior and social withdrawal. Over the past 6 months, he has become increasingly isolated, stopped attending classes, and spends most of his time in his room. His parents report that he talks to himself and sometimes laughs for no apparent reason.On interview, he appears disheveled and avoids eye contact. He reports hearing voices that comment on his actions and believes his professors are sending him secret messages through emails. He speaks in a disorganized manner and often gives irrelevant answers. He shows little emotional expression and has difficulty initiating conversation. Which class of medication is the most appropriate first-line treatment for this patient?
