Introduction: Current drug treatments for schizophrenia are only partially effective and combination/augmentation strategies are commonly used. Nitric Oxide (NO) may play a role in the pathophysiology of schizophrenia. L-arginine is the precursor of NO. In this study, we aimed to investigate whether L-arginine add-on to current medication might improve positive, negative, and depressive symptoms in schizophrenia/schizoaffective disorder patients in partial remission.
