This systematic review and meta-analysis examined the efficacy and safety of combination therapy with antidepressants and sleep medication for treating MDD with insomnia compared to antidepressant monotherapy by sleep medication class (benzodiazepine, Z-drug, melatonin receptor agonist, and orexin receptor antagonist). This study was preregistered with PROSPERO (CRD42025636571). PubMed, CENTRAL, and Embase were searched for double-blind randomized controlled trials published until June 2024, resulting in eight eligible studies (1945 participants; eszopiclone = 4, zolpidem = 2, triazolam = 1, ramelteon = 1). Meta-analyses were performed based on six trials of Z-drugs. Compared with antidepressant monotherapy, combination therapy with antidepressants and Z-drugs resulted in higher remission rates from depressive symptoms (risk ratio: 1.25, 95% confidence interval [CI]: 1.08-1.45, P = 0.003), greater improvement in depressive symptoms (standardized mean difference [SMD]: 0.17, 95% CI: 0.01-0.33, P = 0.04) and insomnia symptoms (SMD: 0.43, 95% CI: 0.28-0.59, P < 0.001) in the short-term (within 12 weeks), with no difference in safety outcomes except for dizziness. Combination therapy with antidepressants and Z-drugs may be more useful for MDD with insomnia symptoms than antidepressant monotherapy in the short term. However, this study did not evaluate the benefits and harms of long-term adjunctive Z-drug therapy. Further long-term studies are needed to draw definitive conclusions regarding the efficacy and safety of combination therapy with antidepressants and Z-drugs. Moreover, further research is warranted to assess whether the findings of this study are applicable to other sleep medication classes.</p>","PeriodicalId":20938,"journal":{"name":"Psychiatry and Clinical Neurosciences","volume":" ","pages":"306-318"},"PeriodicalIF":6.2,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12131207/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143664477","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
