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 .
Duloxetine, 60 mg once daily, for major depressive disorder: a randomized double-blind placebo-controlled trial.
BACKGROUND Despite treatment advances , major depressive disorder ( MDD ) is still a significant cause of morbidity and mortality . Current therapies frequently fall short of providing full remission . In addition , physical symptoms are commonly seen in MDD patients , increasing overall morbidity and health care utilization . Duloxetine hydrochloride , a dual reuptake inhibitor of serotonin and norepinephrine , was evaluated for efficacy and tolerability/safety in the treatment of MDD and associated physical symptoms . METHOD In this multicenter , double-blind , parallel-group study , adult patients with DSM-IV MDD were r and omly assigned to receive placebo ( N = 122 ) or duloxetine ( 60 mg/day , N = 123 ) for 9 weeks . The primary efficacy measure was the 17-item Hamilton Rating Scale for Depression ( HAM-D-17 ) total score . Painful physical symptoms were assessed using visual analog scales , and global illness and quality of life were evaluated using the Clinical Global Impressions-Severity scale , the Patient Global Impressions-Improvement scale , and the Quality of Life in Depression Scale . Safety and tolerability were determined by monitoring discontinuation rates , adverse events , vital signs , and laboratory results . RESULTS Duloxetine was significantly superior to placebo ( p < .001 ) in reducing HAM-D-17 total scores , starting at week 2 . The estimated probability of remission for duloxetine-treated patients ( 44 % ) was almost 3 times that of placebo patients ( 16 % ) . Duloxetine significantly reduced painful physical symptoms in comparison with placebo .  Discontinuation due to adverse events for duloxetine-treated patients ( 13.8 % ) compared favorably with the rates reported for SSRIs in other studies . Nausea , dry mouth , and somnolence were the most common adverse events ; no significant incidence of hypertension was seen . CONCLUSION Duloxetine , 60 mg/day , is a well-tolerated and effective treatment for MDD that reduces painful physical symptoms . These findings suggest that duloxetine may be a first-line treatment for patients with MDD and associated painful physical symptoms
