Background: Schizophrenia is a severe mental disorder characterized by positive, negative, affective, and cognitive symptoms. Affective symptoms in patients with schizophrenia have traditionally been overlooked or even neglected because they are not considered as fundamental as positive and negative symptoms in the choice of medication. Methods: This paper aims to systematically evaluate the efficacy and safety of lurasidone in the treatment of depressive symptoms of schizophrenia. Results: Lurasidone appears to be particularly effective on the depressive symptomatology of schizophrenia while also alleviating the positive and negative symptoms associated with the illness. Conclusions: The efficacy of lurasidone in treating patients with first-episode psychosis who present with predominant depressive symptoms suggests that this medication may be a valuable treatment option not only for established cases of schizophrenia but also for individuals in the early stages of the illness. The good tolerability of lurasidone is an important factor that may positively influence treatment decisions.
