A 5-day study, forming the initial part of two 32-day clinical trials and involving 22 unipolar depressed inpatients, was designed to determine the relationship between response to sleep deprivation and 24-hour urinary MHPG levels. A statistically significant, positive relationship was noted between the sleep deprivation, modified total HAM-D scores and MHPG levels at postsleep deprivation, indicating that the greater the severity of depression during sleep deprivation the higher were the MHPG levels after the sleep deprivation period.

Onset and time course of antidepressant effect were examined in 47 patients with major depressive disorder who had been randomly assigned to twice weekly bilateral, brief pulse electroconvulsive therapy plus one simulated treatment per week (ECTx2) or to a three times weekly schedule of administration (ECTx3). Rapid improvement was observed in the ECTx3 group in whom the number of real ECTs to 30% reduction on the Hamilton Depression Scale (HAM-D) was 3.2 +/- 1.90, administered over 7.3 +/- 4.43 days and to 60% reduction, 5.9 +/- 3.09 real ECTs over 13.7 +/- 7.21 days. Among the responders in both groups combined, 24.3 +/- 29.58% of the overall improvement in HAM-D was contributed by the first real ECT, 60.9 +/- 28.13% by the first four real ECTs and 91.6 +/- 25.82% by the first eight. Although 85.3% of the responders had reached 60% HAM-D improvement after eight ECTs, a clinically significant minority (14.7%) responded later in the course (ECT 9-12). However, response was predictable on the basis of symptomatic improvement (30% on the HAM-D) by the sixth real ECT. Thirty-three out of 34 responders would have been correctly identified by this criterion and only 2 out of 13 non-responders mis-identified (P < 0.000001). Once achieved, the antidepressant effect was stable, without continuation pharmacotherapy, until 1 week after the last treatment and on lithium carbonate (Li) or Li plus clomipramine for a further 3 weeks. These findings confirm the clinical impression that ECT is a rapidly effective treatment for major depression with a shorter latency than generally reported for antidepressant drugs.(ABSTRACT TRUNCATED AT 250 WORDS)

Fluoxetine is an efficacious, nonsedative antidepressant, but its selective efficacy on symptoms of insomnia has not been thoroughly explored. In this analysis, the effects of fluoxetine versus placebo on symptoms of insomnia were evaluated in three clinical subgroups: patients with baseline sleep disturbance, melancholia, or reduced rapid eye movement (REM) latency. Eighty-nine outpatients with major depression completed 2 nights of polysomnography (PSG) and were randomized to fluoxetine or placebo. Within each subgroup of patients, fluoxetine was statistically significantly more effective than placebo in improving non-sleep Hamilton Rating Scale for Depression (HAM-D) items (HAM-D-17 total minus scores from Items 4, 5, and 6). Numerical improvement in HAM-D sleep total (sum of HAM-D Items 4, 5, and 6) was also seen for fluoxetine versus placebo. Fluoxetine did not exacerbate sleep disturbance either at Week 1 or at endpoint. These findings suggest that fluoxetine is an effective antidepressant in patients with baseline sleep disturbance, melancholia, and reduced REM latency.

Patients diagnosed with major depressive disorder (MDD) and enrolled in an open-label safety surveillance study of a sustained release formulation of bupropion hydrochloride (100 to 300 mg/day) were evaluated with the Hamilton Rating Scale for Depression (HAM-D) immediately before and 6 to 12 weeks after the initiation of drug treatment. Auditory event-related potentials (ERPs) recorded under a stimulus intensity modulation paradigm were also obtained at these times. Patients were classified as responders and nonresponders based on post-treatment HAM-D scores, with responders having HAM-D scores less than 10 and nonresponders having scores greater than 10. Consistent with our previous findings, responders exhibited significantly larger positive slope coefficients for P2 ERP component amplitudes as a function of auditory stimulus intensity obtained at baseline and were not affected by bupropion treatment. Thus, these results further support our previous finding that ERP amplitude/intensity functions measured under a stimulus intensity modulation paradigm provide information about the likelihood of a positive therapeutic response to antidepressant pharmacotherapy in patients with MDD and extends these results to bupropion, a pharmacologically atypical antidepressant agent.

This was a prospective, double-blind, randomized, multicenter trial comparing moclobemide once daily (OD) with three times daily (TDS) dosing. The duration of the study was 6 weeks with the initial dose of moclobemide being 450 mg/day (either 450 mg in the morning or 150 mg three times daily). Placebo tablets were used to ensure that the study was double blind. After 2 weeks, the dose could be increased to 600 mg/day if tolerability was acceptable and efficacy was judged insufficient by the investigator. Patients were assessed at baseline and at days 3, 7, 14, 21, 28, and 42. Efficacy was primarily judged on the Hamilton Rating Scale for Depression (HAM-D) (17item). Patients had to score at least 17 to enter the study. Safety and tolerability were judged on reported adverse events, safety parameters, premature withdrawals, and a physicians' global tolerability rating. There were also three secondary efficacy parameters--the Hamilton Rating Scale for Anxiety, Visual Analogue Scales for pain and irritability, and physicians' Clinical Global Impression (CGI). A total of 130 evaluable patients were required to detect a difference of more than 20% (alpha = 0.05 and beta = 0.8) between groups. A total of 189 patients entered the study, and the standard analysis comprised 145 patients. The efficacies between the two dosing regimens as determined by the HAM-D score and from the CGI were found not to differ significantly. For the standard analysis population, there was a reduction in mean HAM-D of 73.8 and 72.9% for the OD and TDS groups, respectively.(ABSTRACT TRUNCATED AT 250 WORDS)

There is no generally accepted definition of severe depression, but hospitalization, high scores on rating scales, and the presence of psychotic symptoms are widely considered to be indicators of severe cases. For the purpose of this analysis of the antidepressant efficacy of the reversible inhibitor of monoamine oxidase A moclobemide, all hospitalized cases were selected from the current database of comparative studies and compared with the standard tricyclics imipramine and clomipramine. The cases from comparisons of moclobemide and imipramine were analyzed together, because in accordance with the recommended range of doses, the dose ratio over all studies was approximately 3:1 (moclobemide: N = 238, mean dose, 453 mg/day; imipramine: N = 248, mean dose, 159 mg/day). The cases from comparisons of moclobemide and clomipramine could only be analyzed over all studies if dose was taken into account, because the dose ratio of approximately 3:1 was only given in one study (moclobemide: N = 62, mean dose, 466 mg/day; clomipramine: N = 66, mean dose, 154 mg/day), whereas the dose ratio over the other, earlier studies was approximately 2:1 (moclobemide: N = 58, mean dose, 258 mg/day; clomipramine, N = 59, mean dose, 124 mg/day). The efficacy as judged on the Hamilton Rating Scale for Depression (HAM-D) and Global Assessment of Efficacy was analyzed for subgroups of inpatients, according to different severity bands (17-item HAM-D baseline total score, cut-off, 28 points) and according to the presence or absence of mood-congruent psychotic features. The results of our analysis failed to reveal any difference in efficacy between moclobemide and imipramine in any subgroup of hospitalized depressives, including patients in the highest HAM-D severity band and psychotic patients.(ABSTRACT TRUNCATED AT 250 WORDS)

In a double-blind, randomized, controlled, multicenter clinical trial in general practice, lasting 7 weeks, a fixed dose of moclobemide (400 mg daily) was compared with a fixed dose of clomipramine (150 mg daily). A total of 147 patients with DSM-III-R major depression were included in the study. After a 1-week drug-free washout period, patients were stratified, according to total scores on the Hamilton Rating Scale for Depression (HAM-D), into two groups--HAM-D total scores, 11 to 15 points, and HAM-D total scores, 16 points or more. A comparison of the therapeutic effect of the two treatments was based on HAM-D total scores and the classification of patients into therapeutic response categories defined on the basis of total rating score, complete response, HAM-D < or = 7 points; partial response, HAM-D, 8 to 15 points; or no response, HAM-D > or = 16 points. The Newcastle Diagnostic Rating Scale (1965) was used to classify the patients into two groups, endogenous and nonendogenous. Adverse events were registered by use of the UKU side effect scale. Clinical global assessments of severity, efficacy, and tolerance were completed during the active treatment period. Compliance to treatment was based on levels of the drugs in plasma and the number of returned capsules. One hundred forty-two patients were evaluated for clinical effects. The results of the efficacy analyses showed therapeutic equivalence between moclobemide and clomipramine. There were no differences in the outcome of the two treatment groups or the two diagnostic groups (endogenous and nonendogenous).(ABSTRACT TRUNCATED AT 250 WORDS)

Seventy inpatients with a DSM-III-R major depression were included in a double-blind, randomized, clinical trial to compare the efficacy and tolerability of moclobemide versus fluoxetine. After a 3-day placebo run-in phase, treatments were administered for 4 weeks in daily doses of between 300 and 600 mg of moclobemide or 20 to 40 mg of fluoxetine. Efficacy was measured by the Hamilton Rating Scale for Depression (HAM-D), Clinical Global Impression, and subjective mood ratings (45-item self-rating scale). Fifty-three patients (mean age, 40 years; 22 men, 31 women) completed the 4-week treatment. Changes between end of treatment and baseline did not differ between both study drugs. The HAM-D responder rate (50% improvement from baseline) was 59% in the moclobemide group and 58% in the fluoxetine group after 4 weeks. Moclobemide, however, acted therapeutically faster than fluoxetine. After 1 week of treatment, the HAM-D scores were significantly lower in patients on moclobemide than in those on fluoxetine (p < 0.005). The earlier efficacy of moclobemide after 1 week was also detected by the patients' subjective mood ratings (p < 0.02). There were no differences between moclobemide and fluoxetine regarding tolerability ratings. These data suggest that both agents have a similar efficacy and tolerability but that moclobemide has an earlier onset of antidepressive action.

The data on a twice-daily dosage schedule with moclobemide in the treatment of a major depressive episode (MDE) is limited. In this randomized, double-blind, multicenter study, moclobemide, 150 mg twice daily, was compared with two different three times daily regimens with total daily dosages of 300 and 450 mg, respectively, over a 6-week period. Two hundred seventy patients were included, of whom 237 completed the study. The treatment groups were comparable with respect to demographic parameters and severity of depression at baseline. No clear differences between the treatment groups could be shown with respect to response on the Hamilton Rating Scale for Depression (HAM-D), the Zung Self Rating Scale, or the Clinical Global Impression of efficacy and severity. There was, however, a slightly higher response rate with respect to the anxiety/agitation subscale of the HAM-D in the 150-mg twice-daily group. In all groups, there was a marked and comparable response with respect to suicide ideation. There were no marked differences between the groups with respect to the type and frequency of adverse events. Tolerability was rated "good" or "excellent" in 93% of patients, and there was no appreciable change in blood pressure, pulse rate, or body weight in any of the treatment groups over the study period. The three dosage schedules of moclobemide studied are effective and well tolerated in the treatment of patients with MDE. Moclobemide, 150 mg twice daily, is the optimal initial daily dosage schedule.

In a multicenter study of 78 severely depressed inpatients (44 women and 34 men; age range, 23 to 70 years), the efficacy, onset of efficacy, and tolerability of the reversible monoamine oxidase-A inhibitor moclobemide (450 mg/day) in combination with thioridazine (100 mg/day) were compared with those of moclobemide (450 mg/day) plus placebo. Patients enrolled met the DSM-III-R criteria for severe depression and had a severity score of at least 20 on the first 17 items of the Hamilton Rating Scale for Depression (HAM-D). Additionally, these patients had not responded to at least two standard antidepressants during the 2 years preceding screening and the mean duration of the current episode was 6 months. After a washout period of 3 to 5 days, patients were randomized to one of the two treatment groups, which at the outset had similar characteristics. Efficacy was assessed by the HAM-D, a depression observation rating for nurses, and a Clinical Global Impression (CGI) scale. Tolerability assessments included an overall rating, a description of adverse events, vital signs, electrocardiogram, and laboratory tests. After 4 weeks of therapy, both groups of patients showed significant improvements in HAM-D and CGI scores. The response rates (based on HAM-D > or = 50% decrease) were 74% for moclobemide/thioridazine and 77% for moclobemide/placebo, and according to CGI scores, 76 and 72% were "very much improved" or "much improved," respectively. Onset of effect was noted after 9.2 and 9.8 days, respectively.(ABSTRACT TRUNCATED AT 250 WORDS)
