In the early post approval period lurasidone-treated patients with bipolar disorder were retrospectively found to have more complex clinical profiles, comorbidities, and prior treatment history compared to patients initiated with other atypical antipsychotics. The study authors suggest this may be due to "the overall clinical profile of lurasidone, the role perceived for lurasidone in the therapeutic armamentarium by practitioners, and the recent introduction of lurasidone into clinical practice during the study period."
