    • Patients entered for trials must have met the DSM criteria for Major Depression (DSM-III-R) or major depressive disorder (DSM-IV)
    • Drugs were given at therapeutic doses for at least 6 weeks

BAP指南: 
             I级证据表明venlafaxine优于SSRIs
  • 根据 BAP 指南, 已有I级证据表明venlafaxine 疗效可能好于SSRIs
  • 其I级证据来自一项对8篇对照研究的meta-analysis, 结果显示 venlafaxine在治疗中度到重度抑郁症病人方面,彻底缓解抑郁症状的疗效明显好于 fluoxetine 和 paroxetine
23
I级证据:   Venlafaxine XL vs SSRIs
                        治疗中度到重度抑郁症病人
