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 .
A placebo-controlled comparison of the effects on sexual functioning of bupropion sustained release and fluoxetine.
BACKGROUND Many antidepressants are associated with  sexual dysfunction  , a side effect that may lead to patients ' dissatisfaction and noncompliance with treatment . OBJECTIVE This study compared the efficacy , tolerability , and effects on sexual functioning of bupropion sustained release ( bupropion SR ) and the selective serotonin reuptake inhibitor fluoxetine . METHODS In this multicenter , r and omized , double-blind , double-dummy , parallel-group study , patients with recurrent major depression were treated with bupropion SR 150 to 400 mg/d , fluoxetine 20 to 60 mg/d , or placebo for up to 8 weeks .  Depression and sexual-functioning status were assessed by site-specific trained investigators at weekly clinic visits ; tolerability was assessed primarily by monitoring adverse events . RESULTS Four hundred fifty-six patients participated in the study , 150 receiving bupropion SR , 154 fluoxetine , and 152 placebo .  The majority of patients in each group completed the study ( 63 % each , bupropion SR [ n = 94 ] and fluoxetine [ n = 97 ] ; 67 % , placebo [ n = 102 ] ) . Bupropion SR and fluoxetine were similarly effective in the treatment of depressive symptoms . Beginning at week 2 and continuing throughout the study , significantly more fluoxetine-treated patients experienced orgasm dysfunction than did patients receiving bupropion SR or placebo ( P < 0.001 ) ; similar results were seen in patients defined as clinical responders ( > or = 50 % decrease from baseline in 21-item Hamilton Rating Scale for Depression [ HAM-D ] total score ) ( P < 0.001 ) and in those experiencing remission of depression ( HAM-D total score < 8) ( P < 0.05 ) . At various time points , worsened sexual functioning , sexual desire disorder , sexual arousal disorder , and dissatisfaction with sexual functioning in those satistied at baseline were more frequently associated with fluoxetine treatment than with bupropion SR or placebo . Both active treatments were well tolerated . CONCLUSIONS Bupropion SR and fluoxetine were similarly effective and well tolerated in the treatment of depression . Fluoxetine , however , was more frequently associated with sexual dysfunction compared with bupropion SR . Bupropion SR may be an appropriate initial choice for the treatment of depression in patients concerned about sexual functioning
