Moclobemide was compared to placebo in two parallel groups of depressed patients, in a multicenter randomized, double-blind study of six weeks treatment duration. Forty seven patients participated in the study: 23 received moclobemide (flexible dose 300-600 mg/day) and 24 placebo. They were evaluated weekly for efficacy and tolerability. Moclobemide was more efficacious than placebo as judged by analysis on the total score on the Hamilton depression scale (p < 0.05) and by the overall assessment of efficacy (p < 0.01). Moclobemide was also more effective than placebo in the subgroup with neurotic depression (p < 0.05). In addition, the number of patients prematurely terminating treatment for inefficacy, was higher in the placebo than in the moclobemide group (12 versus 2, p < 0.01). The number and the severity of side-effects tended to be slightly greater in the moclobemide than in the placebo group, but this did not reach a level of significance. Cardiovascular tolerability was good in both treatment groups. No hypertensive crisis was reported. Hematology, clinical chemistry and urine analysis were not affected by the treatment in any clinically significant fashion.

Whilst tricyclic antidepressants are efficacious in all depressive syndromes, classical MAO-inhibitors differ substantially from them in their action. They are considered less effective in general and not very effective in endogenous depression, but recommended for the treatment of 'atypical' depression. A new class of RIMA (Reversible Inhibitors of MAO-A) represented by moclobemide requires a change in clinical thinking on antidepressants. Moclobemide shows the same efficacy in depression as tricyclics: its effects are similar in unipolar and bipolar affective disorders, and in patients with major depressive episode superimposed on dysthymia (double depression). As with classical antidepressants, the response rate tends to be lower, but is still present in psychotic depression. Agitated depressives do not respond less well than non-agitated patients to moclobemide. Patients meeting DSM-III-R criteria for major depression with melancholia tend to respond better than non-melancholics, but this may be associated with the significantly higher baseline severity observed in melancholics. A slightly higher response rate in patients without concomitant benzodiazepine treatment, compared to those with benzodiazepine comedication, may also be related to baseline differences in the severity of depression. Elderly depressives respond less well than younger patients to classical antidepressants, but with moclobemide, elderly patients do as well as younger ones.

Moclobemide is a reversible and selective inhibitor of the enzyme monoamine oxidase (MAO) subtype A with a broad spectrum of antidepressant activity. Controlled clinical studies suggest that the short term clinical efficacy of moclobemide is significantly superior to that of placebo, and comparable to that of the tricyclic antidepressants clomipramine, amitriptyline, imipramine and desipramine, the irreversible MAO inhibitor tranylcypromine and the second-generation antidepressants maprotiline, mianserin and fluvoxamine in the treatment of major depressive illness. Moclobemide appears to be equally effective in endogenous and nonendogenous depression, producing marked amelioration of clinical features of psychomotor retardation and depressed mood. Moclobemide is well tolerated, being largely devoid of the anticholinergic adverse effects, symptomatic postural hypotension and weight gain variously associated with the tricyclic antidepressants and irreversible MAO inhibitors, and appears considerably safer on overdosage than the tricyclic and second generation antidepressants. Moreover, moclobemide offers the advantage over the older, irreversible MAO inhibitors of causing only minimal potentiation of the pressor response to dietary tyramine (the so-called 'cheese effect'). Consequently, the risk of potentially fatal hypertensive crisis, a major deterrent to the wider acceptance of these earlier compounds, is substantially reduced with moclobemide, and the need for dietary precautions is minimised. With its efficacy against endogenous and nonendogenous depression, relatively rapid onset of antidepressant activity, and absence of carry-over effects on treatment withdrawal, moclobemide is likely to make an important contribution to the treatment of major depressive illness. Its favourable tolerability profile, safety on overdosage and beneficial effect on age-related cognitive impairment may be of particular value in the elderly and those with concurrent physical illness.

The objective of this study was to determine if moclobemide is an effective treatment for depression and if it is well tolerated by patients. A randomized, double-blind placebo-controlled trial was conducted in a tertiary ambulatory clinic which treats depression. Fifty-five patients participated. They fit the DSM-III-R criteria for major depressive episode, scored at least 18 on the 17 item Hamilton Rating Scale for Depression (HRSD), were between the ages of 18 and 65, and were not suffering from a major medical illness. After a one week washout period, patients were randomly selected to receive placebo, amitriptyline or moclobemide for up to six weeks. Moclobemide is a well-tolerated medication at therapeutic doses; it is globally as effective as amitriptyline in the treatment of major depression.

A double-blind comparison of moclobemide and toloxatone was performed in adult out-patients diagnosed as suffering from a major depressive disorder. Parallel groups of patients received moclobemide, 450 mg/day (n = 135) or toloxatone, 1000 mg/day (n = 133) for 28 days. Both groups showed a significant clinical improvement while on therapy; the response was most marked and rapid in those receiving moclobemide treatment. Improvement was greatest in those patients with the most severe depression at the time of trial onset. A significantly higher number of patients returned to normal sleep patterns following moclobemide treatment than following toloxatone. Overall, tolerance was rated as good or very good in more than 80% of patients. The most frequent complaints in the moclobemide-treated group were hot flushes, dry mouth, constipation and headache, while an increase in anxiety was associated with toloxatone usage. Moclobemide was found to be as effective as toloxatone in the treatment of major depressive episodes, but with the advantages of improved sleep patterns and reduced anxiety.

Moclobemide is a reversible inhibitor of the monoamine oxidase type A. In clinical studies, more than 3900 patients have been treated with moclobemide for depression. Eighteen of these patients attempted suicide by overdosing moclobemide with or without other drugs. All patients recovered fully without leaving signs of cardio- or hepatotoxicity. Moclobemide can safely be prescribed for in- and out-patient treatment of depression.

A review of the clinical efficacy of four structurally distinct antidepressant drugs is presented. Their antidepressant activity can be rationalised within current pharmacological hypotheses of drug action, despite markedly different effects on "in vitro" testing. Fluoxetine, a specific serotonin re-uptake inhibitor, has proven safe, effective treatment for depressive illness and may have a role to play in the treatment of obsessive-compulsive disorder and panic attacks. While it has few of the anticholinergic side effects of the tricyclic antidepressants, nausea, tremor, headache, weight loss, nervousness and sweating are side effects most frequently reported. Minaprine, a compound with weak MAO inhibiting properties and effects on serotonergic receptors, has clinical efficacy in the treatment of depression based on several comparative studies. It is claimed that minaprine lacks anticholinergic and sedative properties. Moclobemide, a specific, reversible inhibitor of MAO-A, has been extensively evaluated in depressive illness. The major advantage of this agent over other irreversible, non-specific MAO inhibitors, is the significant attenuation of the so-called "cheese effect" with doses of tyramine likely to be encountered in foodstuffs. Rolipram, a phosphodiesterase inhibitor, represents a new approach to antidepressant treatment. Limited clinical data suggest that the drug may be an effective antidepressant with few side effects. The place of these agents in therapy is yet to be established.

Moclobemide was compared with isocarboxazide and clomipramine in patients with depression. A total of 167 outpatients were allocated to daily treatment with 300 mg moclobemide, 30 mg isocarboxazide or 150 mg clomipramine for 6 weeks. Moclobemide was slightly inferior to clomipramine, whereas isocarboxazide had an intermediate position. There was no interaction between treatment and atypical or nonatypical depression. Anticholinergic symptoms and orthostatic hypotension were most pronounced in the clomipramine group.

The design and the main therapeutic results of 3 controlled double-blind studies comparing moclobemide with tricyclics and/or placebo in depressed patients are presented. Moclobemide, a reversible inhibitor of monoamine oxidase (RIMA), preferentially inhibits MAO-A. It showed good efficacy in major depression (DSM-III), both endogenous and non-endogenous. The 3 studies included a total of 763 patients. The therapeutic results are similar to those observed with tricyclics (2/3 good responders). Tolerability was significantly better. The onset of action was evaluated in 2 studies and was faster in the patients treated with moclobemide. The fact that reversible inhibitors of MAO-A demonstrate good efficacy independently of the diagnostic category of depression is an important new finding.

Moclobemide was compared with placebo for antidepressant activity, tolerance and safety in 2 parallel groups of 23 and 24 depressed patients. At the end of treatment (4 weeks or longer), 9 patients on moclobemide (41%) showed an improvement greater than or equal to 50% on the Hamilton Rating Scale for Depression, compared with only 4 (17%) of those on placebo. The overall assessment of efficacy was significantly better for moclobemide (good or very good results in 50% of patients) than for placebo (80% poor results). Moclobemide was well or very well tolerated by 85% of patients and placebo by 100%. Moclobemide was thus shown to be clearly more effective than placebo and only slightly less well tolerated.
