We found no clear evidence that paroxetine was more or less effective compared with other antidepressants at increasing response to treatment at acute ( six to 12 weeks ) , early ( one to four weeks ) , or longer term follow-up ( four to six months ) .
Paroxetine was associated with a lower rate of adverse events than amitriptyline , imipramine and older ADs as a class , but was less well tolerated than agomelatine and hypericum .
Some possibly clinical ly meaningful differences between paroxetine and other ADs exist , but no definitive conclusions can be drawn from these findings .
In terms of early response to treatment ( one to four weeks ) there was moderate quality of evidence that mirtazapine was better than paroxetine and that paroxetine was better than reboxetine .
However there was no clear evidence that paroxetine was better or worse compared with other antidepressants at increasing response to treatment at any time point .
BACKGROUND Paroxetine is the most potent inhibitor of the reuptake of serotonin of all selective serotonin reuptake inhibitors ( SSRIs ) and has been studied in many r and omised controlled trials ( RCTs ) .
However , these comparative studies provided contrasting findings and systematic review s of RCTs have always considered the SSRIs as a group , and evidence applicable to this group of drugs might not be applicable to paroxetine alone .
The present systematic review assessed the efficacy and tolerability profile of paroxetine in comparison with tricyclics ( TCAs ) , SSRIs and newer or non-conventional agents .

Onset and Early Behavioral Effects of Pharmacologically Different Antidepressants and Placebo in Depression
This study was aim ed at resolving the time course of clinical action of antidepressants ( ADs ) and the type of early behavioral changes that precede recovery in treatment-responsive depressed patients . The first goal was to identify , during the first 2 weeks of treatment , the onset of clinical actions of the selective serotonin reuptake inhibitor ( SSRI ) , paroxetine , and the selective noradrenergic reuptake inhibitor , desipramine ( DMI ) . The second aim was to test the hypothesis that the two pharmacologic subtypes would induce different early behavioral changes in treatment-responsive patients . The design was a r and omized , parallel group , placebo-controlled , double-blind study for 6 weeks of treatment following a 1-week washout period . The study utilized measures of the major behavioral components of the depressive disorder as well as overall severity . The results indicated that the onset of clinical actions of DMI ranged from 3 to 13 days , averaged 13 days for paroxetine , and was 16–42 days for placebo . Furthermore , as hypothesized , the different types of ADs initially impacted different behavioral aspects of the disorder . After 1 week of treatment , DMI produced greater reductions in motor retardation and depressed mood than did paroxetine and placebo , and this difference persisted at the second week of treatment . Early improvement in depressed mood – motor retardation differentiated patients who responded to DMI after 6 weeks of treatment from those that did not . Paroxetine initially reduced anxiety more in responders than in nonresponders , and by the second week , significantly improved depressed mood and distressed expression in responders to a greater extent . Depressed patients who responded to placebo showed no consistent early pattern of behavior improvement . Early drug-specific behavioral changes were highly predictive of ultimate clinical response to the different ADs , results that could eventually be applied directly to clinical practice
