This randomized, double-blind, parallel-group design study of 100 outpatients with major depressive disorder is the first study in the United States to compare the efficacy and tolerability of fluvoxamine (100-150 mg/day) and fluoxetine (20-80 mg/day). After a variable, single-blind, washout period, patients were randomized to receive either fluvoxamine (51 patients) of fluoxetine (49 patients) for 7 weeks. Efficacy was assessed with the 21-item Hamilton Rating Scale for Depression (HAM-D), and Clinical Global Impressions scale for severity and improvement. Eighty-four percent of each treatment group completed the study with each group having a mean score at end point of less than 10. Both groups demonstrated a 60% improvement in HAM-D scores over the 7-week trial. There were no statistically significant differences observed between the two groups on any efficacy parameter. The medications were well tolerated, with only two patients in each group who were terminated because of side effects. There were differences in the side-effect profiles, with fluvoxamine being associated with less nausea than fluoxetine. In summary, fluvoxamine and fluoxetine were equally effective in reducing depressive symptoms, but the two drugs displayed slightly different side-effect profiles.

Patients meeting the social phobia criteria of the revised third edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-III-R) on the DSM-III-R Structured Clinical Interview (n = 101) entered a long-term moclobemide treatment study. These patients were treated for 2 years with moclobemide (phase I) followed by drug withdrawal, in most cases abruptly (phase II). Those who relapsed entered phase III for a further period of 2 years of treatment. During phase I 40 patients (39.6%) withdrew due to inefficacy or relapse. Two patients were removed from the study because of other diagnoses (borderline or schizophreniform). At the end of phase I the remaining patients (58.4%) were rated as not ill (45.5%) or minimally ill (11.9%). Effort was taken to achieve the maximum dose of moclobemide (750 mg/day) and the mean (+/-SD) dose was 723.3 +/- 67.7 mg/day (month 21). A marked decrease in symptoms in the patients who responded was recorded on the Liebowitz Scale for Social Phobia, Clinical Global Impressions. Hamilton Anxiety Scale and Hamilton Depression Scale. Non-response was mainly associated with co-morbidity, especially alcohol abuse, axis II disorders, and a history of major depression or secondary dysthymia. The drug was well tolerated; the more frequent side effects were mild and occurred mainly in the first 2 months of phase I, including nausea, headaches or insomnia. In phase II there was a relapse rate of 88% and 51 patients entered phase III; these patients are still being treated.

We report the results of a double-blind study comparing the efficacy and safety of low-dose (10-50 mg) and high-dose (20-100 mg) ranges of gepirone-extended release (ER) and placebo in 145 outpatients with major depressive disorder. At multiple time points and endpoint (Week 6), statistically significant reductions in Hamilton Rating Scale for Depression (HAM-D) scores were recorded for high-dose gepirone-ER compared to placebo. Analysis of the 17-item HAM-D and 28-item HAM-D scores indicated a relatively early onset of antidepressant efficacy with statistically significant results at treatment Weeks 1, 2, 4, and 6. A rapid response was evident in the high-dose group, beginning at Week 1 (p < .05). The most frequently reported adverse experiences were headache, nausea, dizziness, and insomnia. The results indicate that gepirone-ER is clearly superior to placebo in terms of antidepressant efficacy. When used at higher doses, gepirone-ER appears to be efficacious, safe, and well-tolerated in depressed out-patients.

The objective of the present study was to compare the safety and efficacy of moclobemide versus fluoxetine in adult patients with major depressive disorder. The design of the study was a multicenter, double-blind, comparative, and randomized trial. A 1- to 2-week single-blind placebo washout phase was followed by 6 weeks of double-blind treatment with moclobemide or fluoxetine. A total of 150 patients were enrolled in the study. There were 128 patients eligible to be randomized, with 66 patients receiving moclobemide and 62 patients receiving fluoxetine. At the termination of the study, patients in the moclobemide group were receiving a mean dose of 440 mg +/- 123 mg, while the mean dose in the fluoxetine group was 35 mg +/- 8 mg. No significant treatment differences were found for any of the efficacy parameters. Headache and nausea were the most frequently reported adverse events in both treatment groups. Headache and blurred vision were reported significantly more often (P < 0.05) in the fluoxetine group, whereas significantly more dry mouth was reported (P < 0.05) in the moclobemide group. These results provide supporting evidence of the comparable efficacy of moclobemide and fluoxetine and the better tolerability of moclobemide when used in the treatment of major depressive disorder.

Nefazodone hydrochloride is a phenylpiperazine antidepressant with a mechanism of action that is distinct from those of other currently available drugs. It potently and selectively blocks postsynaptic serotonin (5-hydroxytryptamine; 5-HT) 5-HT2A receptors and moderately inhibits serotonin and noradrenaline (norepinephrine) reuptake. In short term clinical trials of 6 or 8 weeks' duration, nefazodone produced clinical improvements that were significantly greater than those with placebo and similar to those achieved with imipramine, and the selective serotonin reuptake inhibitors (SSRIs) fluoxetine, paroxetine and sertraline. The optimum therapeutic dosage of nefazodone appears to be between 300 and 600 mg/day. Limited long term data suggest that nefazodone is effective in preventing relapse of depression in patients treated for up to 1 year. Analyses of pooled clinical trial results indicate that nefazodone and imipramine produces similar and significant improvements on anxiety- and agitation-related rating scales compared with placebo in patients with major depression. Short term tolerability data indicate that nefazodone has a lower incidence of adverse anticholinergic, antihistaminergic and adrenergic effects than imipramine. Compared with SSRIs, nefazodone causes fewer activating symptoms, adverse gastrointestinal effects (nausea, diarrhoea, anorexia) and adverse effects on sexual function, but is associated with more dizziness, dry mouth, constipation, visual disturbances and confusion. Available data also suggest that nefazodone is not associated with abnormal weight gain, seizures, priapism or significant sleep disruption, and appears to be relatively safe in overdosage. Nefazodone inhibits the cytochrome P450 3A4 isoenzyme and thus has the potential to interact with a number of drugs. Further long term and comparative studies will provide a more accurate assessment of the relative place of nefazodone in the management of major depression. Nonetheless, available data suggest that nefazodone is a worthwhile treatment alternative to tricyclic antidepressants and SSRIs in patients with major depression.

Major depressive disorder and dysthymia are twice as prevalent in women as in men, and the lifetime risk of a woman's developing a major depressive disorder is about 20%. Yet depression is often unrecognized or misdiagnosed in women, and only about one quarter of women who meet criteria for major depressive disorder receive appropriate therapy. Until recently, women were generally excluded from clinical drug trials because of concerns of inadvertent pregnancy and risk of teratogenicity. Thus, information on safety and efficacy in those most likely to require antidepressant therapy is lacking. Studies have shown that the antidepressant fluoxetine, a selective serotonin reuptake inhibitor (SSRI) has a more tolerable side effect profile than do tricyclic amine (TCA) antidepressants, but few data have been reported on the efficacy and tolerability of fluoxetine or other SSRIs in female patients. In this study, a retrospective analysis of 11 randomized, double-blind, well-controlled trials was done to compare data from 427 female patients on fluoxetine and 423 female patients on TCAs. Both fluoxetine and TCAs significantly reduced the HAMD17 total mean score from baseline to end point, week 5 (fluoxetine, 24.35 to 14.37; TCAs, 24.57 to 14.43; p < 0.001). Both treatment groups were associated with significant reductions in the HAMD17 anxiety/somatization and insomnia subfactor scores. Abnormal vision, constipation, dizziness, dry mouth, and somnolence occurred more frequently (p < 0.05) in the TCA group. Insomnia and nausea were the only adverse events more common (p < 0.05) in the fluoxetine group. This study demonstrates that fluoxetine is an effective and tolerable agent for the treatment of major depressive disorder in women.

A 41-year-old woman with a strong history of postoperative nausea and vomiting presented for abdominal hysterectomy 3 months after a previous anaesthetic where ondansetron prophylaxis had been used. She had developed a severe acute major depression disorder almost immediately thereafter, possibly related to the use of a serotonin antagonist. Nine years before she had experienced a self-limited puerperal depressive episode. Anaesthesia with a propofol infusion and avoidance of serotonin antagonists provided a nausea-free postoperative course without exacerbation of the depression disorder.

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.

This 12-week, double-blind, placebo-controlled study evaluated the efficacy and safety of venlafaxine as first-line therapy for the treatment of major depression and major depression associated with anxiety in 384 adult outpatients. Fixed total daily dosages of 75, 150, and 200 mg of venlafaxine were administered in a twice-a-day regimen. Primary efficacy parameters were the Hamilton Rating Scale for Depression (HAM-D) total score, the HAM-D Depressed Mood Item, the Montgomery-Asberg Depression Rating Scale total score, and the Clinical Global Impressions Scale. Overall, a higher percentage of patients responded to venlafaxine than to placebo. Efficacy data indicated a dose-related response, most evident in the onset of clinical improvement; statistically significant improvements in some primary parameters were seen as early as 1 to 2 weeks after initiation of treatment, especially in the 150-and 200-mg/day groups. These dose-related clinical improvements continued through week 12. Venlafaxine-treated patients who had depression associated with anxiety showed significant dose-related improvements compared with placebo-treated patients; improvement was noted by scores on the HAM-D Anxiety-Psychic Item and Anxiety-Somatization Factor. Few clinically significant changes were observed in laboratory values, vital signs, or electrocardiogram tracings. Venlafaxine was generally well tolerated at all dosages. The most common study events included nausea, dizziness, somnolence, insomnia, dry mouth, and asthenia, which are consistent with findings of previous studies. The current study demonstrated that 75 to 200 mg/day of venlafaxine twice daily produced a dose-related improvement in the primary efficacy parameters and in the onset of significant antidepressant effects, which was noted at weeks 1 to 2 with the highest dosage tested (200 mg/day). The study also demonstrated that these dosages of venlafaxine were safe and effective as first-line therapy for major depression and depression associated with anxiety.

The effects of once-daily venlafaxine extended release (XR) 75-225 mg/day on symptoms of anxiety in depressed outpatients were assessed in two randomized, double-blind, placebo-controlled trials. In study 1, venlafaxine XR was significantly (p < or = 0.05) more effective than placebo by week 4 in relieving anxiety symptoms among patients with moderate or greater anxiety (anxiety-psychic item score > or = 2) at baseline. Among patients with severe (anxiety-psychic item score > or = 3) anxiety, venlafaxine XR was significantly (p < or = 0.05) more effective than placebo beginning at week 6. In study 2, among patients with moderate or greater anxiety (score > or = 2) at baseline, a significant reduction (p < or = 0.05- < or = 0.001) in HAM-D anxiety-psychic item scores was noted with venlafaxine XR compared with placebo from weeks 1 to 8. Among patients with severe anxiety (score > or = 3) at baseline, venlafaxine XR produced a significant reduction (p < or = 0.05- < or = 0.001) in the anxiety-psychic item score compared with placebo from weeks 1 to 8. Discontinuation for adverse events occurred in 11% of patients on venlafaxine XR, and the most common adverse events were nausea, dizziness, insomnia, somnolence and dry mouth. These results indicate that once-daily venlafaxine XR is effective for the treatment of anxiety symptoms associated with major depression in doses ranging from 75 to 225 mg/day.
