Conclusion Fluoxetine was not statistically different in either tolerability or efficacy when compared with duloxetine .
Venlafaxine was significantly superior to duloxetine in all analyses except dropout rate .
In the absence of relevant data from head-to-head comparison trials , results suggest that venlafaxine is superior compared with duloxetine and that duloxetine does not differentiate from fluoxetine
Background Data comparing duloxetine with existing antidepressant treatments is limited .
A comparison of duloxetine with fluoxetine has been performed but no comparison with venlafaxine , the other antidepressant in the same therapeutic class with a significant market share , has been undertaken .
In the absence of relevant data to assess the place that duloxetine should occupy in the therapeutic arsenal , indirect comparisons are the most rigorous way to go .
We conducted a systematic review of the efficacy of duloxetine , fluoxetine and venlafaxine versus placebo in the treatment of Major Depressive Disorder ( MDD ) , and performed indirect comparisons through meta-regressions .
Once-daily venlafaxine extended release (XR) compared with fluoxetine in outpatients with depression and anxiety. Venlafaxine XR 360 Study Group.
BACKGROUND We conducted a r and omized , double-blind , placebo-controlled study of the efficacy and safety of once-daily venlafaxine extended release ( XR ) and fluoxetine in out patients with major depression and concomitant anxiety . METHOD Patients who met DSM-IV criteria for major depressive disorder and satisfied eligibility criteria were r and omly assigned to once-daily venlafaxine XR , fluoxetine , or placebo for 12 weeks . Efficacy was assessed with the Hamilton Rating Scale for Depression ( HAM-D ) , Hamilton Rating Scale for Anxiety ( HAM-A ) , and Clinical Global Impressions scale . RESULTS Among 359 out patients , venlafaxine XR and fluoxetine were significantly superior ( p < .05 ) to placebo on the HAM-D total score beginning at week 2 and continuing to the end of the study . Venlafaxine XR but not fluoxetine was significantly better than placebo at week 2 on the HAM-D depressed mood item . At week 12 , the HAM-D response rate was 43 % on placebo , 67 % on venlafaxine XR , and 62 % on fluoxetine ( p < .05 ) . The HAM-D remission rate was significantly higher ( p < .05 ) at weeks 3 , 4 , 6 , 8 , 12 , and final evaluation with venlafaxine XR and at weeks 8 , 12 , and final evaluation with fluoxetine than with placebo . The HAM-A response rate was significantly higher ( p < .05 ) with venlafaxine XR than with fluoxetine at week 12 . The incidence of discontinuation for adverse events was 5 % with placebo , 10 % with venlafaxine XR , and 7 % with fluoxetine . CONCLUSION Once-daily venlafaxine XR is effective and well tolerated for the treatment of major depression and concomitant anxiety and provides evidence for superiority over fluoxetine
