A metaregression analysis indicated that , after adjusting for possible confounders , studies where fluoxetine was the experimental agent were positively associated with treatment effect , indicating a significant advantage for fluoxetine .
The evidence that the outcome of fluoxetine trials varied according to whether this drug was used as a new compound or a reference one suggests the presence of bias
The present study investigated whether the outcome of r and omized clinical trials study ing fluoxetine favored fluoxetine , where this was the experimental agent , and favored comparator antidepressants in trials where fluoxetine was the reference agent .
A double‐blind, comparative, multicentre study comparing paroxetine with fluoxetine in depressed patients
A r and omized , double‐blind , parallel‐group , 6‐week study was undertaken to compare the efficacy and tolerability of once or twice daily administration of the selective serotonin reuptake inhibitors paroxetine and fluoxetine . After a 1‐week placebo wash‐out , patients suffering from DSM‐III major depression and with a score of 18 or more on the 21‐item Hamilton Rating Scale for Depression ( HRSD ) received either paroxetine or fluoxetine . The patients were assessed for efficacy using the HRSD , Montgomery‐Åsberg Depression Rating Scale and Clinical Global Impression ; for tolerability , adverse events were elicited by the use of a non‐leading question and a side effects checklist . The groups of patients were comparable on entry to the study . One hundred patients were recruited into the study , of whom 78 were evaluable for the efficacy analysis .  Paroxetine and fluoxetine showed comparable efficacy at the end of the 6‐week treatment period , but a statistically significant difference in the number of responders at week 3 in favour of paroxetine was observed . This could suggest an earlier onset of action with paroxetine .  Also , associated anxiety symptoms were significantly reduced on paroxetine compared with fluoxetine at week 3 . Patients on paroxetine reported fewer adverse events than those on fluoxetine . The most commonly reported adverse events were nausea and vomiting in both groups
