Combination of NMDA-enhancing and Antioxidant Treatments for Schizophrenia
Source: ClinicalTrials.gov · Last updated 23 Oct 2026
Brief summary (registry, in English)
Previous studies found that some NMDA-enhancing agents were able to improve clinical symptoms of patients with schizophrenia. In addition, several drugs with antioxidant properties have been tested in clinical trials for the treatment of schizophrenia too. Whether combined treatment of an NMDA-enhancing agent and a drug with antioxidant property can be better than an NMDA-enhancing agent alone deserves study.
