其他摘要:Abstract Introduction: Given the role of opioids and their antagonists on dopamine secretion, the effect of naltrexone use in the treatment of schizophrenia was evaluated in this study. Method: In a double blind placebo controlled clinical trial study on a group of 34 patients with schizophrenia on maintenance therapy with antipsychotics, 17 patients received naltrexone (50 mg, BID ) and 17 patients received placebo (BID) . The patients were evaluated at the start of the trial, as well as three and six weeks after, using Positive and Negative Syndrome Scale (PANSS) . Results: Patients receiving naltrexone showed improvement in positive symptoms from week three to week six, and improvement in negative symptoms from week one to week three. Conclusion: Naltrexone had no significant effect on positive or negative symptoms of schizo-phrenia compared to placebo.
