1 The effects of fluvoxamine to a maximum of 300 mg daily were compared with those of imipramine to a maximum of 200 mg daily, in 151 patients with primary major depression. 2 Four weeks of treatment with fluvoxamine resulted in 67.2% improvement (+/- s.d. 21.6) on the Hamilton Rating Scale for Depression (26 items). Treatment with imipramine showed 62.1% improvement (+/- s.d. 29.5) on this scale. 3 Fluvoxamine had no untoward effects on the cardiovascular system, while imipramine produced systematic increases in the postural fall in blood pressure. Dry mouth, nausea, daytime somnolence and tremor were seen with fluvoxamine treatment, while imipramine was associated with dry mouth, daytime somnolence, dizziness and tremor. 4 We conclude that fluvoxamine seems to have the same general antidepressant efficacy as imipramine. It was not associated with any safety problems and was generally well tolerated.

Seven hundred twelve patients meeting DSM-III-R criteria for major depression and recommended for antidepressant treatment were treated with moclobemide as outpatients (88%) or inpatients in ordinary psychiatric practices. These differ from the highly selected patients usually studied in antidepressant research, without comorbidity, or coprescription and treated in special clinics. Sixty-five percent were women, with a mean age of 45 (+/- 13.6) years, and 88% were outpatients. Eighty-eight percent had preexisting depression. Eight percent had prior manic episodes. Previous antidepressant treatment for this episode had been received by 69%, with the most common reasons for change to moclobemide being inadequate response (66%) and poor tolerability (20%). The modal final dose was 450 mg. Regarding tolerability, 52% did not report adverse events. The most common adverse events were insomnia or stimulation (13%), nausea (11%), headache or migraine (11%), dizziness or disorientation (6%), sedation or drowsiness (5%), agitation or nervousness (3%), and diarrhea (3%). Only 10% of adverse events were severe, and 83% lasted less than 2 weeks. There was no difference when moclobemide followed fluoxetine use. Most adverse events did not significantly differ from the frequencies reported in double-blind placebo-controlled studies. Concomitant medications from all major drug groups were taken by 520 patients (73%), with no adverse interactions. Moclobemide overdose resulted in an uneventful recovery, whereas mixed overdoses caused no problems other than those attributable to coprescribed medication. On physician clinical global impression, 65% were moderately improved or better after 8 weeks.(ABSTRACT TRUNCATED AT 250 WORDS)

Venlafaxine has been shown in clinical trials to be safe and well tolerated in patients with major depression. Data were pooled from 19 studies in which 2181 patients were given venlafaxine, 451 were given placebo and 591 were given a reference antidepressant (imipramine, trazodone, clomipramine, maprotiline, dothiepin or amineptine). Long-term safety was evaluated in 422 patients who were given venlafaxine for at least 1 year; as well, a total of 229 elderly patients have been treated with venlafaxine, including 66 who were given it for at least 1 year. The adverse events that occurred during short-term treatment in > or = 10% of patients were nausea, headache, insomnia, somnolence, dry mouth, dizziness, constipation, asthenia, sweating and nervousness. In comparator-controlled trials, the frequency of anticholinergic events with the reference agents was approximately twice that with venlafaxine. The safety profile and patient acceptability of venlafaxine are comparable to those of third-generation antidepressants, and possibly better than those of first-generation agents.

Tianeptine is a novel antidepressant agent, both structurally (modified tricyclic) and in terms of its pharmacodynamic profile. Unlike other antidepressant agents, tianeptine stimulates the uptake of serotonin (5-hydroxytryptamine; 5-HT) in rat brain synaptosomes and rat and human platelets, increases 5-hydroxyindoleacetic acid (5-HIAA) levels in cerebral tissue and plasma, and reduces serotonergic-induced behaviour. Tianeptine reduces the hypothalamic-pituitary-adrenal response to stress, antagonises stress-induced behavioural deficits and prevents changes in cerebral morphology. The antidepressant efficacy of tianeptine, as shown in 2 trials of patients with major depression or depressed bipolar disorder with or without melancholia, is greater than that of placebo. In patients with major depression without melancholia or psychotic features, depressed bipolar disorder or dysthymic disorder, the antidepressant efficacy of short term (4 weeks to 3 months) tianeptine therapy appears to be similar to that of amitriptyline, imipramine and fluoxetine and may be superior to that of maprotiline in patients with coexisting depression and anxiety. However, submaximal dosages of amitriptyline and maprotiline were used in these studies. Preliminary evidence suggests that tianeptine may also be effective in patients with endogenous depression. Progressive therapeutic improvements have been observed with up to 1 year of tianeptine treatment, and long term therapy may reduce the rate of relapse or recurrence. Tianeptine is effective in the treatment of depression in elderly and post-alcohol-withdrawal patient subgroups. Tianeptine was more effective in reducing psychic anxiety than placebo in patients with major depression or depressed bipolar disorder with or without melancholia. The overall anxiolytic properties of tianeptine in patients with coexisting depression and anxiety appear to be similar to those of amitriptyline, imipramine and fluoxetine and may be superior to those of maprotiline, although submaximal dosages of amitriptyline and maprotiline were used. Studies of tianeptine in patients with primary anxiety have not been conducted. Tianeptine is well tolerated in the short (3 months) and long (up to 1 year) term. The incidence of dry mouth (38 vs 20%), constipation (19 vs 15%), dizziness/syncope (23 vs 13%), drowsiness (17 vs 10%) and postural hypotension (8 vs 3%) are greater with amitriptyline than with tianeptine. Insomnia and nightmares occur in more tianeptine than amitriptyline recipients (20 vs 7%). The relative lack of sedative, anticholinergic and cardiovascular adverse effects with tianeptine makes it particularly suitable for use in the elderly and in patients following alcohol withdrawal; these patients are known to have increased sensitivity to the adverse effects associated with psychotropic drugs.(ABSTRACT TRUNCATED AT 400 WORDS)

In a 6-week double-blind study, 220 patients with major depression (mostly outpatients) were randomly assigned to receive a fixed dose of brofaromine 150 mg daily (n = 111) or placebo (n = 109) after a 1-week single-blind placebo washout. Except for the HAM-D sleep items, brofaromine was superior to placebo on measures of depression as determined by the four methods of assessing drug efficacy: (1) psychiatric symptom rating (HAM-D 17-item less the three sleep items); (2) self-rating scale (Beck Depression Inventory); (3) Clinical Global Assessment of Efficacy; and (4) drop-out rate due to lack of efficacy. Most commonly reported adverse events with brofaromine were: headache, nausea, dizziness and sleep disturbance. Brofaromine was found to be an effective antidepressant, superior to placebo with a good tolerability profile.

The pharmacology, pharmacokinetics, and clinical efficacy of venlafaxine hydrochloride, a new antidepressant, are described. Venlafaxine inhibits the reuptake of serotonin, norepinephrine, and, to a lesser extent, dopamine. In animal models, it does not significantly inhibit muscarinic, histaminic, or adrenergic receptor activity and does not inhibit monoamine oxidase. Venlafaxine is rapidly absorbed and metabolized in the liver to its active metabolite, O-desmethylvenlafaxine (ODV). Time to peak concentration is one to two hours for the parent compound and four to five hours for ODV. The pharmacokinetics of venlafaxine might be dose-dependent, although pharmacokinetic studies have had conflicting results. The major route of elimination is renal; thus, patients with renal dysfunction may require lower doses. In double-blind, placebo-controlled trials of venlafaxine for maintenance therapy, venlafaxine has shown effective antidepressant activity in severely ill patients with major depression. Antidepressant effectiveness may be apparent within two weeks; this finding needs to be replicated. The dosage is 75-375 mg/day administered in two or three divided doses. The strength of the antidepressant response may be correlated with increasing dosage. Nausea is the most commonly reported adverse drug reaction (ADR). Others include somnolence, dizziness, dry mouth, and sweating. All ADRs have commonly occurred at the beginning of therapy and decreased with time. Overall, venlafaxine is well tolerated. Venlafaxine is as effective as other available antidepressants. It may cause fewer anticholinergic, antihistaminic, and antiadrenergic ADRs and may have a quicker onset of therapeutic action than existing antidepressants.

In a double-blind multi-centre study of general practice patients with DSM-III-R major depressive disorder, sertraline (50 or 100 mg/day) was compared with dothiepin (75 or 150 mg/day) and with placebo. There were 83, 96 and 90 patients evaluated in the respective treatment groups; treatment lasted 6 weeks. Patients were assessed on the MADRS, CGI, and Leeds Self-rating Scales. Statistically significant differences (p < 0.05) between sertraline and placebo were found on MADRS and CGI but not the Leeds Scales. In the mild subgroup analyses, there were no significant differences between sertraline and placebo. However, clear significant differences (p < 0.05) between sertraline and placebo were present in the severe subgroup. Dothiepin failed to achieve a statistically significant difference from placebo on any analyses. Seventy-six per cent of patients were treated with 50 mg sertraline and 81% of patients received 150 mg dothiepin. Both sertraline and dothiepin were generally well tolerated; the most frequent side effects with sertraline were nausea, dizziness and headache; with dothiepin the most frequent side effects were dry mouth, somnolence and headache.

A double-blind, placebo-controlled trial was undertaken to compare the safety and efficacy of venlafaxine and trazodone in patients with major depression. Two hundred twenty-five patients entered an initial 6-week treatment phase, and 149 completed it. Ninety-six patients who were responders continued in a 1-year, double-blind, long-term phase during which they received the same medication and doses they had during the short-term phase. Both active treatments were significantly more effective than placebo on some measures during the short-term study, but venlafaxine produced more improvement in the cognitive disturbance and retardation factors on the Hamilton Rating Scale for Depression. Trazodone was more effective against the sleep disturbance factor. Patients on venlafaxine were most likely to enter the long-term phase and to remain in the trial longest. The side effect profiles of the three treatment groups were compared. Venlafaxine was most likely to cause nausea, whereas trazodone was associated with the most dizziness and somnolence.

In a double-blind study the selective monoamine oxidase-A inhibitor brofaromine was compared with the classical MAOI tranylcypromine in 39 patients with major depression resistant to treatment with tricyclic antidepressants. Concerning efficacy no significant differences were found. Ten out of 22 patients responded to brofaromine and 5 out of 17 patients to tranylcypromine. Adverse effects favoured brofaromine. Although orthostatic hypotension occurred in both groups, severe decrease in blood pressure and dizziness occurred significantly more with tranylcypromine. Both MAOIs caused a decrease in stage 4 and REM sleep and an increase in REM latency. In most patients receiving tranylcypromine REM sleep was completely abolished.

Tiagabine (TGB) hydrochloride is a potential new antiepileptic drug (AED) undergoing clinical development. Experience in humans amounts to 1,810 patient-years of exposure. TGB was found to be tolerated in an integrated safety analysis of five double-blind, add-on therapy trials involving approximately 1,000 patients with epilepsy with difficult-to-control seizures with existing AEDs. Discontinuation resulting from adverse events were infrequent, occurring in 15% of patients receiving TGB compared to 5% receiving placebo. The most frequently reported adverse event was dizziness, which was usually transient and did not require medical intervention. Adverse events that were statistically significantly more common with TGB than placebo were dizziness, asthenia, nervousness, tremor, diarrhea, and depression (not major depression). Adverse events were usually mild to moderate in severity and transient, and most were associated with dose titration. The incidence, type, and severity of adverse events in long-term studies were comparable with those in short-term studies. Serious adverse events were uncommon and no idiosyncratic events were reported.
