Major Depressive Disorder
Venlafaxine Randomized Controlled Trials
Phillip W. Long M.D. (July 25, 2006)
Venlafaxine has been shown to be effective in the treatment of Major Depressive Disorder in adults, but not in children or adolescents:
Four studies (1, 3, 4, 5) have shown venlafaxine to produce a better remission
rate than placebo or a comparison medication.
Two studies (2, 11) have shown venlafaxine to better prevent relapse
Five studies ( 6, 7, 8, 9) have shown venlafaxine to produce a better response
rate than placebo or a comparison medication.
One study (10) showed that venlafaxine was ineffective
for Major Depressive Disorder in childhood and adolescence.
” in these studies was actually an “active placebo
”. That is, the patient would
regularly see a psychiatrist for counseling AND receive an inert substance that both the psychiatrist and the patient believed was an antidepressant medication. Thus, part of the improvement due to the “placebo” could be caused by the counseling.
Venlafaxine’s remission rate is usually twice that of placebo (3, 4) and ranges from 37% to 59%.
Venlafaxine has been shown to have a high discontinuation rate:
Three studies (3, 6, 11) reported discontinuation rates of 30% or higher.
Discontinuation rates for venlafaxine ranged from 9% to 62%.
Venlafaxine hasn’t been conclusively shown to be superior to other modern antidepressant medications:
Venlafaxine has only been compared twice to paroxetine (1, 3), and in the second study venlafaxine had a 39% discontinuation rate.
Venlafaxine has only been compared three times to fluoxetine (1, 4, 5). Only two out of the three studies showed that venlafaxine was superior to fluoxetine.
Apart from paroxetine, fluoxetine, and imipramine; venlafaxine hasn’t been compared “head-to-head” with other antidepressant medications in the treatment of Major Depressive Disorder.
None of these studies published the “Effect Size” of venlafaxine vs. the comparison treatment. Without knowing the “Effect Size”, it is very difficult to estimate the clinical significance of these research findings (despite the millions of dollars invested in this research).
The majority of the venlafaxine studies only measured response rates
(6, 7, 8, 9, 10, 12, 13) instead of more clinically useful information (like remission rates
, relapse rates
and discontinuation rates
Only four studies measured remission rates
(1, 3, 4, 5).
Only two studies (2, 11) measured relapse rates
Less than half of the studies published their discontinuation rates
(3, 4, 5, 6, 11, 13).
I question why so many of these studies only published their response rates
(and failed to publish their remission rates
and discontinuation rates
). Since remission rates
for all antidepressant medications are embarrassingly low (e.g., 37% to 59% for venlafaxine [3, 4]) and discontinuation rates
are embarrassingly high (e.g., up to 39% at 12 weeks for venlafaxine ), do pharmaceutical companies have a bias against publishing remission rates
and discontinuation rates
for their antidepressants?
Notwithstanding all of the above, I commonly use venlafaxine in my psychiatric practice since it is one of the most effective antidepressant medications currently available. However, sudden withdrawal from long-term use of venlafaxine can trigger a very uncomfortable (but not medically dangerous) withdrawal syndrome. I avoid triggering this withdrawal syndrome by taking at least 2 months to slowly wean my patients off venlafaxine.

Venlafaxine XR demonstrates higher rates of sustained remission compared to fluoxetine, paroxetine
or placebo. Shelton C

The combined serotonin-norepinephrine reuptake inhibitor, venlafaxine XR, has demonstrated significant
response and remission in patients diagnosed with depression when measured with the Hamilton Depression
Rating Scale (HAM-D). This pooled analysis of data from five studies compared the sustained remission of
depressive symptoms in patients treated with venlafaxine XR, the selective serotonin reuptake inhibitors
(SSRIs) fluoxetine or paroxetine, or placebo. Data from 1391 subjects enrolled in five active and placebo-
controlled studies who met the DSM-III-R or DSM-IV criteria for major depressive disorder were analysed.
Three treatment groups were compared: venlafaxine XR (n = 560), fluoxetine/paroxetine (n = 298) and
placebo (n = 496). Mean treatment duration was 8 weeks. Responders were defined as those patients whose
HAM-D-21 score decreased by > or = 50% from baseline. Remission was defined as a HAM-D-17 score < or
= 7. Sustained remission was defined as maintenance of remission through week 8 or the end of treatment (if
before week 8) and for > or = 2 weeks. Between-group rate comparisons in outcome measures were carried
out using Fisher's exact and log-rank tests. Venlafaxine XR produced significantly higher rates of sustained
remission in depressed patients compared to fluoxetine/paroxetine or placebo over this 8-week treatment
period. As early as week 2, a significantly greater proportion of patients treated with venlafaxine achieved improved depression scores (remission and response). A significantly greater rate of remission and sustained remission occurred with venlafaxine compared to placebo. Remission was achieved earlier with venlafaxine and lasted throughout the remainder of the study. These results demonstrate that venlafaxine XR is more effective than fluoxetine/paroxetine for sustaining remission of depressive symptoms. PMID: 15933485

Many studies have demonstrated that venlafaxine is an efficacious and safe treatment for major depressive
disorder (MDD). This double-blind, placebo-controlled study was performed to evaluate the efficacy of
venlafaxine extended-release (XR) (75-225 mg/day) in the prevention of relapse of depression. Patients with
MDD who responded to an 8-week course of venlafaxine XR treatment, i.e., had a score < or = 3 on the
Clinical Global Impressions scale-Severity of Illness item (CGI-S) and a 21-item Hamilton Rating Scale for
Depression (HAM-D(21)) score < or = 10, were randomly assigned to receive continuation treatment (up to 6
months) with venlafaxine XR (n=161) or placebo (n=157). The main efficacy outcome measure was the
number of patients who experienced a relapse of depression. Relapse was defined by either a combination of
a patient meeting Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria for MDD
and a CGI-S score > or = 4, two consecutive CGI-S scores > or = 4, or a final CGI-S score > or = 4 for a
patient who withdrew from the study. The cumulative probability of relapse was calculated using the Kaplan-
Meier method of survival analysis. During the 6-month evaluation period, significantly more patients in the
placebo group had a relapse of MDD than did patients who continued treatment with venlafaxine XR.
Cumulative relapse rates at 3 and 6 months were 19 and 28%, respectively, for venlafaxine XR, and 44 and
52%, respectively, for placebo. This study demonstrates that venlafaxine XR is an effective and safe

A 24-week, double-blind, randomized trial was performed to compare the efficacy and tolerability of
venlafaxine and paroxetine in patients with major depression or dysthymia. Outpatients aged 18-70 years
with a baseline score of 17 on the 21-item Hamilton Depression Rating Scale (HAM-D) were eligible.
Patients were randomly assigned to venlafaxine, 37.5 mg, in the morning and evening or paroxetine, 20 mg,
in the morning and placebo in the evening, which could be increased to venlafaxine, 75 mg twice daily, or
paroxetine, 20 mg twice daily, after 4 weeks. Efficacy was assessed with the 21-item HAM-D, the
Montgomery-Asberg Rating Scale, the Hamilton Anxiety Rating Scale, and the Clinical Global Impressions
Scale. Forty-one patients were randomized to venlafaxine and 43 to paroxetine. At week 6, a response was
observed in 55% of patients on venlafaxine and 29% on paroxetine (P = 0.03). At week 12, significantly (P =
0.011) more patients in the venlafaxine group had a HAM-D remission score of 8 or less (59% versus 31%).
Discontinuation for any reason occurred in 16 (39%) patients on venlafaxine and 11 (26%) on paroxetine.
The most common adverse events were nausea (28%), headache (18%) and dry mouth (15%) with
venlafaxine and headache (40%) and constipation (16%) with paroxetine. Venlafaxine was effective and well
tolerated for the treatment of patients with mild to moderate depression or dysthymia. A consistently higher
proportion of patients had a response or remission on venlafaxine than on paroxetine.

A double-blind, randomized, placebo-controlled trial of once-daily venlafaxine extended release (XR)
and fluoxetine for the treatment of depression. Rudolph RL
, Feiger AD
Clinical Research and Development, Wyeth-Ayerst Research, Radnor, PA 19101, USA.
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.

Department of Psychiatry, University of Alberta, Edmonton, Canada.
BACKGROUND: We conducted a randomized, double-blind, placebo-controlled study of the efficacy and
safety of once-daily venlafaxine extended release (XR) and fluoxetine in outpatients with major depression
and concomitant anxiety. METHOD: Patients who met DSM-IV criteria for major depressive disorder and
satisfied eligibility criteria were randomly assigned to once-daily venlafaxine XR, fluoxetine, or placebo for
12 weeks. Efficacy was assessed with the Hamilton Rating Scale for Depression (HAM-D), Hamilton Rating
Scale for Anxiety (HAM-A), and Clinical Global Impressions scale. RESULTS: Among 359 outpatients,
venlafaxine XR and fluoxetine were significantly superior (p < .05) to placebo on the HAM-D total score
beginning at week 2 and continuing to the end of the study. Venlafaxine XR but not fluoxetine was
significantly better than placebo at week 2 on the HAM-D depressed mood item. At week 12, the HAM-D
response rate was 43% on placebo, 67% on venlafaxine XR, and 62% on fluoxetine (p < .05). The HAM-D
remission rate was significantly higher (p < .05) at weeks 3, 4, 6, 8, 12, and final evaluation with venlafaxine
XR and at weeks 8, 12, and final evaluation with fluoxetine than with placebo. The HAM-A response rate
was significantly higher (p < .05) with venlafaxine XR than with fluoxetine at week 12. The incidence of
discontinuation for adverse events was 5% with placebo, 10% with venlafaxine XR, and 7% with fluoxetine.
CONCLUSION: Once-daily venlafaxine XR is effective and well tolerated for the treatment of major
depression and concomitant anxiety and provides evidence for superiority over fluoxetine.

Clinical Research and Development, Wyeth-Ayerst Research, Radnor, PA, USA.
BACKGROUND: We examined the efficacy and safety of three different dosages of venlafaxine
hydrochloride (75, 225, and 375 mg/day) in a multicenter, randomized, double-blind, placebo-controlled,
four-group study. METHOD: Outpatients, 18 to 65 years old, who met DSM-III criteria for major depression
were included (N = 358 randomized; 194 completed). Of the total patients completing the trial, 59%, 56%,
51%, and 51% were in the placebo, 75-mg, 225-mg, and 375-mg groups, respectively. The primary outcome
measures were the Hamilton Rating Scale for Depression (HAM-D21) total, HAM-D21 depression item,
Montgomery-Asberg Depression Rating Scale total, and Clinical Global Impressions scale. RESULTS: Each
dosage of venlafaxine was associated with statistically significant improvement as compared with placebo,
based on the intent-to-treat sample. The two higher dosages were associated with a modestly greater
antidepressant response than was the 75-mg dosage. Nausea, dizziness, somnolence, and anorexia were the
most common adverse events attributable to venlafaxine. Since headache occurred at a similar frequency in
both the drug and placebo groups, we did not consider it to be attributable to venlafaxine use. Withdrawal
from the study due to adverse events occurred in 5%, 17%, 24%, and 30% of the patients in the placebo, 75-
mg, 225-mg, and 375-mg groups, respectively. CONCLUSION: Venlafaxine, at dosages of 75-375 mg/day,
is an effective and well-tolerated antidepressant. With increasing dosage, greater efficacy and possibly more
adverse effects will occur.

University of Pittsburgh, WPIC, PA 15213, USA.
BACKGROUND: This was a randomized, double-blind, placebo-controlled evaluation of the efficacy and
safety of once-daily venlafaxine extended release (XR) in out-patients with DSM-IV major depression.
METHOD: Patients were randomly assigned to venlafaxine XR (75-225 mg) once daily or placebo for up to
8 weeks. The primary efficacy variables were the 21-item Hamilton Rating Scale for Depression (HAM-D)
total score and HAM-D depressed mood item, the Montgomery-Asberg Depression Rating Scale (MADRS)
total scores, and the Clinical Global Impressions (CGI) Severity scale. Data were analyzed on a modified
intent-to-treat basis using the last-observation-carried-forward method. RESULTS: Venlafaxine XR (N = 91)
was significantly more effective than placebo (N = 100) beginning at Week 2 on the CGI Severity scale, at
Week 3 on the HAM-D depressed mood item, and at Week 4 on the HAM-D and MADRS; this superiority
was maintained through Week 8. The most common treatment-emergent adverse events associated with
venlafaxine XR were nausea, insomnia, and somnolence. The incidence of nausea was highest during the first
week, decreased by 50% during the second week, and was comparable to that of placebo from Week 3
onward. CONCLUSION: These results demonstrate that venlafaxine XR is an effective and well-tolerated
treatment of major depression.

with major depression. Venlafaxine XR 208 Study Group. Cunningham LA
Vine Street Clinical Research Center, Springfield, Illinois 62701, USA.
This was a randomized, double-blind, placebo-controlled comparison of the efficacy and safety of once-daily venlafaxine extended release (XR) and venlafaxine immediate release (IR). Outpatients with DSM-III-R major depression were randomly assigned to venlafaxine XR, 75 mg once daily, venlafaxine IR, 37.5 mg twice daily, or placebo for a maximum of 12 weeks. If the response was inadequate after 2 weeks of treatment, the dosage of venlafaxine XR or IR could be increased to 150 mg daily. The primary efficacy variables were the 21-item Hamilton Depression (HAM-D) Rating Scale total score and depressed mood item, the Montgomery-Asberg Rating Scale (MADRS) total scores, and the Clinical Global Impressions (CGI) severity scale. Two hundred seventy-eight patients were evaluated for efficacy. Venlafaxine XR was significantly superior (p < 0.05) to placebo beginning at week 2 for the HAM-D, week 3 for the MADRS, and week 4 for the CGI severity. Similarly, venlafaxine IR was significantly superior (p < 0.05) to placebo beginning at week 2 on the HAM-D total and depressed mood item, week 3 on the MADRS total, and week 6 on the CGI severity scales. Venlafaxine XR exhibited superiority (p < 0.05) over venlafaxine IR at week 12 for all efficacy variables. The most common treatment-emergent adverse event with venlafaxine XR was nausea. The incidence of nausea was highest during the first 2 weeks with a low likelihood of developing nausea thereafter. The results of this study indicate that venlafaxine XR is safe, effective, and well tolerated for the treatment of major depression at once-daily doses ranging from 75 to 150 mg. PMID: 9339881

A double-blind, placebo-controlled study of 229 patients with a Research Diagnostic Criteria diagnosis of
major, minor or intermittent depression was used to compare the clinical profiles of venlafaxine and
imipramine in general practice. Venlafaxine produced a significant improvement compared to placebo in
symptoms of depression and anxiety as rated by the total MADRS and percentage of responders, the CGI
improvement, the CGI severity of illness, the BSA psychic anxiety item and the HSCL. On a number of these
measures, venlafaxine was also significantly more effective than imipramine. Venlafaxine was significantly
superior to both imipramine and placebo for the SARS total score and the items 'social/leisure' and 'extended
family.' A similar proportion of patients discontinued treatment in each group, but fewer patients on
venlafaxine discontinued treatment because of an unsatisfactory response.

Venlafaxine in the treatment of children and adolescents with major depression. Mandoki MW
, Tapia MR
, Tapia MA

, Parker JL
University of Florida Health Science Center, Jacksonville, USA.
Major depression is commonly found in the child and adolescent population. Venlafaxine, a new
antidepressant, has been used successfully in adults; however, its use in children and adolescents has been
very limited. This study evaluated the efficacy and side effect profile of venlafaxine in the treatment of
depression in children and adolescents. In a double-blind, placebo-controlled, 6-week study, 33 subjects
between the ages of 8 and 17, who met DSM-IV criteria for major depression, were treated with either
venlafaxine and therapy or placebo and therapy. Patient progress data were obtained by weekly rating
assessments. Data on side effects were also obtained weekly. The statistical analysis indicated a significant
improvement over time, but it could not be attributed to venlafaxine drug therapy. These findings are
consistent with other studies where the efficacy of antidepressants in the treatment of major depression in this
age population remains unproven. Low dosage and short length of treatment may account for the lack of
efficacy. The findings did, however, suggest a low side-effect profile. Further studies are recommended to
assess efficacy and to corroborate its safety in children and adolescents.

Clinical Research and Development, Wyeth-Ayerst Research, Philadelphia, Pennsylvania 19101-1245, USA.
The objective of this analysis was to determine the efficacy of venlafaxine in comparison with that of placebo
during long-term treatment. A pooled analysis of relapse rates in outpatients with major depression
continuing long-term treatment (up to 12 months) after responding to short-term treatment (6 weeks) was
performed combining the data from four randomized, double-blind, placebo-controlled clinical trials.
Relapses were defined as two consecutive Clinical Global Impression (CGI) severity scores greater than 3
(mildly ill), as a CGI severity score greater than 3 at withdrawal regardless of the reason for withdrawal, or as
withdrawal due to lack of efficacy. Data from 304 patients (185 venlafaxine, 119 placebo) well balanced for
baseline characteristics were included in the pooled analysis. Percentages of patients completing the long-
term phase were 38% venlafaxine and 26% placebo (p = 0.034). Cumulative relapse rates by 6 months of
long-term treatment were 11% venlafaxine and 23% placebo (p = 0.019). Cumulative relapse curves for the
venlafaxine and placebo groups over the 1-year long-term treatment differed significantly (p = 0.022). The
results from this analysis indicate that long-term treatment with venlafaxine in patients with major depressive
disorder is effective in maintaining the initial response compared with placebo and suggest that venlafaxine
will be effective in the prevention of relapse.

The antidepressant efficacy and safety of venlafaxine was shown previously in 6-week, placebo-controlled
trials. We evaluated the long-term safety and clinical acceptability of venlafaxine and imipramine in a
double-blind, parallel-group, comparative study. Two hundred ninety depressed outpatients were treated with
venlafaxine, and an additional 91 received imipramine for as long as clinically necessary, up to 1 year. The
total daily dose of each drug could vary from 75 to 225 mg. The Clinical Global Impressions Scale and a
therapeutic response rate that was based on Clinical Global Impressions Scale-Improvement and incorporated
discontinuation information were used to evaluate efficacy. Safety determinations and patient subjective
ratings were used to evaluate safety and clinical acceptability. During the study, the adverse events were
generally mild to moderate and most subsided with continued treatment; the most frequent were nausea for
venlafaxine and dry mouth for imipramine. The anticholinergic side effect burden was significantly higher in
the imipramine group than in the venlafaxine group. Venlafaxine was judged significantly more acceptable
than imipramine, on the basis of the subjective ratings by patients. Fewer venlafaxine-treated patients than
imipramine-treated patients withdrew because of adverse events and unsatisfactory response. There was a
consistent trend in the therapeutic response rates in favor of venlafaxine that reached statistical significance at
months 2, 6, and 12. In this long-term study, patient acceptability was greater for venlafaxine than for
imipramine, suggesting therapeutic advantages for venlafaxine in the long-term treatment of depression.
Additional studies with other active comparators are underway to confirm and extend these encouraging

Comparison of venlafaxine and imipramine in the acute treatment of major depression in outpatients. Schweizer E
, Feighner J
, Mandos LA
, Rickels K
Department of Psychiatry, University of Pennsylvania, Philadelphia. BACKGROUND: Venlafaxine is a new phenylethylamine antidepressant that exhibits monoamine reuptake inhibition. The current study evaluates the efficacy of venlafaxine compared to that of imipramine in outpatients suffering from major depression of moderate-to-marked severity. METHOD: We conducted a double-blind, placebo-controlled, 6-week treatment study of 224 outpatients who met DSM-III-R criteria for major depression, and who had a score of at least 20 on the 21-item Hamilton Rating Scale for Depression (HAM-D). Dosage was flexible and administered on a three-times-a-day schedule, with a mean maximum daily dose of 182 mg for venlafaxine and 176 mg for imipramine. RESULTS: For patients completing 6 weeks of treatment with venlafaxine, the HAM-D total score improved by 16.6 +/- 4.9 points. Improvement at 6 weeks was 13.6 +/- 6.3 points for patients treated with imipramine and 10.6 +/- 7.8 points for patients treated with placebo (p < .05 for active drug vs. placebo). Ninety percent of venlafaxine completers were rated as "much" or "very much" improved on the Clinical Global Impression-Improvement scale, compared to 79% treated with imipramine and 53% treated with placebo (p < .05). An endpoint analysis, where the last scores of patients who dropped out were carried forward to subsequent visits, showed significant efficacy only for venlafaxine and not imipramine, probably because of the higher attrition for the latter drug. Overall, both venlafaxine and imipramine were well-tolerated, with venlafaxine having a somewhat lower attrition rate due to adverse effects than imipramine (16% vs. 25%). CONCLUSION: These results, together with those of previously reported studies, suggest that venlafaxine has antidepressant efficacy comparable to that provided by available antidepressants.
