Abstract

Background We compared the efficacy and tolerability of venlafaxine XR with that of fluoxetine in a multicenter, randomized, double-blind, placebo-controlled study in depressed outpatients.Methods Outpatients, 18 years and older, who met DSM-IV criteria for major depressive disorder were included (n = 301 randomized; 232 completed). Patients were randomly assigned to eight weeks of treatment with either venlafaxine XR 75-225 mg/day (n = 100), fluoxetine 20-60 mg/day (n = 103), or placebo (n = 98). The primary efficacy outcome measures were the final ratings on the Hamilton Rating Scale for Depression (HAM-D21) total score, HAM-D21 depressed mood item, Montgomery-Asberg Depression Rating Scale total score, and Clinical Global Impressions Scale.Results Withdrawal from the study due to adverse events occurred in 6% of the patients in the venlafaxine XR group and 9% of the patients in the fluoxetine group. Patients treated with venlafaxine XR, but only rarely those treated with fluoxetine, had statistically significant improvements in their depression ratings compared with placebo at the end of the study. The percentages of patients who achieved full remission of their depression (HAM-D21 total score < or = 7) at the end of treatment were 37%, 22% and 18% for the venlafaxine XR, fluoxetine and placebo groups, respectively. The differences in remission rates between venlafaxine XR and the other groups were statistically significant (p < 0.05).Limitations The superior remission outcome observed with venlafaxine XR treatment needs to be replicated in additional studies.Conclusion Venlafaxine XR is a well-tolerated and efficacious treatment for depression. The results of this study suggest that venlafaxine XR is as well-tolerated as fluoxetine but may have some efficacy advantages over fluoxetine.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
