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 .
Comparison of pramipexole, fluoxetine, and placebo in patients with major depression.
Pramipexole , a dopamine D2 receptor agonist , was tested in 174 patients with major depression , with or without melancholia and without psychotic features . Three daily dose levels ( 0.375 mg , 1.0 mg , and 5.0 mg ) were compared to fluoxetine ( Prozac ) at 20 mg and placebo in a r and omized , double-blind , parallel-group study . After a 1 week placebo run-in period , patients were treated for 8 weeks , had a post- study follow-up ( week 9 ) , and were evaluated primarily with the Hamilton Psychiatric Rating Scale for Depression ( HAM-D ) , the Montgomery-Asberg Depression Rating Scale ( MADRS ) , and the Clinician 's Global Impressions-Severity of Illness scale ( CGI-SI ) .  All patients who received one dose of study medication were included in the observed-case analysis ( no missing data were replaced ) . Results indicated that by endpoint ( week 8) , patients receiving pramipexole at the 1.0 mg per day dose had significant improvement over baseline compared to the placebo group by measure of the HAM-D , MADRS , and CGI-SI . Significant improvement in this dose group was seen at other timepoints as well . The most obvious improvement was seen in the pramipexole 5.0 mg group , although a substantial dropout rate for this group precluded statistical tests vs. placebo late in the study . Patients taking fluoxetine also showed significant improvements at endpoint on the MADRS and earlier in the study on the HAM-D. No new or unusual safety concerns were generated during this study . Pramipexole helped safely alleviate the symptoms of depression at 1.0 mg per day and especially in those patients who could tolerate the escalation to 5 mg per day
