A study comparing paroxetine placebo and imipramine in depressed patients.

These data provide evidence for the antidepressant efficacy of paroxetine. Paroxetine- and imipramine-treated patients were significantly different from placebo-treated patients, but little different to each other, on all depressive outcome measures. However, paroxetine appeared to have a possibly greater and earlier beneficial effect on anxiety symptoms associated with depression, when compared with imipramine. Both active therapies were effective in treating patients with severe depression. Side effects for paroxetine were typical of other serotonin (5-HT) uptake inhibitors but different from those of imipramine. In particular, anticholinergic and cardiovascular symptoms were reduced, and premature withdrawal less likely.

Use of buspirone in patients with generalized anxiety disorder and coexisting depressive symptoms. A meta-analysis of eight randomized, controlled studies.

This report presents the results of a retrospective analysis of pooled efficacy data from eight studies in which buspirone was compared to placebo in 520 patients with generalized anxiety disorder (GAD). In addition to evaluating overall efficacy in the composite patient data base, four criteria were used to identify subsets of patients with GAD who had coexisting depressive symptoms of at least moderate intensity: (1) a score of > or = 2 on the Hamilton Anxiety (HAM-A) Rating Scale item 6 (depressed mood), (2) a score of > or = 2 on the Hamilton Depression (HAM-D) Rating Scale item 1 (depressed mood), (3) a HAM-D total score of > or = 18, or (4) a HAM-D Retardation Factor value (items 1, 7, 8, and 14) greater than the median for the group. Overall, patients treated with buspirone demonstrated significant (p < or = 0.001) improvement over baseline in total HAM-A scores compared to patients who received placebo. Buspirone also produced significant (p < or = 0.001) global improvement compared to placebo as assessed by the attending physician. Of the GAD patients stratified according to the four criteria for coexisting depressive symptoms, a substantial percentage (44-64%) of the total patient sample exhibited significant depressive symptoms as part of their anxiety disorder. Patients with GAD and coexisting depressive symptoms of at least moderate intensity exhibited significantly greater improvement with buspirone compared to placebo treatment regardless of the stratification criterion used. They also responded at least as well or better to buspirone therapy as did those with GAD who had less intense depressive symptoms.(ABSTRACT TRUNCATED AT 250 WORDS)

A 6-week, double-blind trial of paroxetine, imipramine, and placebo in depressed outpatients.

Paroxetine is a novel antidepressant that selectively inhibits neuronal reuptake of serotonin. Results are reported from a 6-week, double-blind trial of paroxetine, imipramine, and placebo in 120 outpatients with DSM-III major depression. Paroxetine was significantly superior to placebo on almost all measures. This included the main outcome variable, the Hamilton Rating Scale for Depression (HAM-D), and its factor scores, anxiety-somatization, cognitive disturbance, psychomotor retardation, and sleep disturbance. There were no significant differences between paroxetine and imipramine on the same scales. Imipramine-treated patients were significantly more likely than those taking placebo to report one or more adverse effects, which were predominantly anticholinergic in nature. There was no significant difference in the number of paroxetine and placebo patients who reported one or more adverse effects. The results of this and similar studies indicate that paroxetine is an effective treatment in major depression and has a favorable side effect profile.

A comparison of paroxetine, imipramine and placebo in depressed out-patients.

To compare the safety and antidepressant efficacy of paroxetine, imipramine, and placebo, data from six centres using the same protocol were pooled. A double-blind parallel-group design was used, with therapy lasting six weeks. From week 2 onwards, both the 240 paroxetine-treated and the 237 imipramine-treated patients were significantly different from the 240 placebo-treated patients, but no different from each other. Side-effects with paroxetine were less likely to lead to drop-out than with imipramine. Paroxetine had a possible earlier antidepressant effect than imipramine, and a possible earlier beneficial effect on anxiety symptoms associated with depression.

Venlafaxine in depressed outpatients.

Venlafaxine is a structurally novel compound with a biochemical and pharmacological profile suggesting antidepressant properties. We report the results of a Phase II, double-blind, placebo-controlled clinical trial assessing the efficacy and safety of venlafaxine in a sample of 93 depressed outpatients. Venlafaxine doses of 25 mg t.i.d., 75 mg t.i.d., and 125 mg t.i.d. were compared to placebo. Patients receiving venlafaxine showed a significantly greater improvement in their mood symptoms compared to those receiving placebo. Venlafaxine was well tolerated and the most common side effect was nausea. There was some evidence to suggest that venlafaxine may have antidepressant activity within the first 2 weeks of treatment.

Comparative efficacy and safety of nortriptyline and fluoxetine in the treatment of major depression: a clinical study.

The safety and efficacy of nortriptyline and fluoxetine were compared in a double-blind, randomized, multicenter 5-week trial involving 205 outpatients with acute major depression of moderate severity. Seventy-two nortriptyline and 84 fluoxetine patients completed at least 2 weeks of medication and were included in the efficacy analysis; all patients were evaluated for side effects. Average total scores on the Hamilton Rating Scale for Depression (HAM-D) for both treatment groups declined from 22-23 at baseline to 11.5 at the conclusion of the 5-week period. At Week, 5, 71% of nortriptyline patients and 65% of fluoxetine patients were much or very much improved. Fluoxetine was associated more frequently with nausea (p less than .05), while nortriptyline was associated more frequently with dry mouth (p less than .05). These results are discussed in the context of selecting between nortriptyline and fluoxetine for a particular depressed patient.

Clinical effects of the 5-HT1A partial agonists in depression: a composite analysis of buspirone in the treatment of depression.

The azapirone class of anxiolytic drugs is being evaluated for clinical use in the treatment of depression. Buspirone, a serotonin (5-hydroxytryptamine, 5-HT) partial agonist active at the 5-HT1A receptor subtype, was evaluated in the treatment of depression in a series of five placebo-controlled, parallel group studies involving 382 patients with DSM-III major depression and significant associated anxiety symptoms (both Hamilton depression [HAM-D] and Hamilton anxiety [HAM-A] scales greater than or equal to 18). Buspirone therapy was initiated at 15 mg/day with individual dose titration to a maximum of 90 mg/day and resulted in marked improvement in both depressive and anxiety symptoms. Analyses of the composite data base from the five studies show significant (p less than 0.05) improvement in mean HAM-D, HAM-A, and Clinical Global Impression-Global Improvement scale ratings for buspirone-treated compared with placebo-treated patients. Of particular interest was significant improvement in cardinal depression symptoms, e.g., depressed mood, guilt, work and interest, anergia, and diurnal variation of mood. Subset analyses revealed that patients with melancholic-type major depression and patients with more severe symptoms (judged by higher initial HAM-D or HAM-A total scores) responded better to buspirone than did patients who were less ill. The buspirone dose most frequently associated with clinically significant improvement was 40 mg/day. Gepirone, an analogue of buspirone with highly selective binding affinity for the 5-HT1A receptor subtype, also shows promise of antidepressant efficacy in preliminary controlled clinical trials. These data suggest that azapirones, which as partial agonists modulate 5-HT1A receptor function, have clinically important antidepressant properties.

Gepirone in the treatment of major depression.

Gepirone is a serotonin (5-hydroxytryptamine, 5-HT) type1A receptor agonist and a pharmacologic analogue of buspirone. Two double-blind, placebo-controlled studies show the efficacy of gepirone in the treatment of major depression. Study 1 demonstrates gepirone's superiority over placebo in an 8-week acute treatment of patients with major depression, including the melancholic subtype. Gepirone's antidepressant dose range is tentatively established at 5-30 mg/day. Study 2 reveals the benefit of gepirone compared with placebo in 4-week continuation therapy of patients with major depression who initially responded to 6 weeks of open therapy with gepirone. Analysis of Hamilton Rating Scale for Depression item scores show gepirone especially improves scores on items of core depression.

Trazodone dosing regimen: experience with single daily administration.

Efficacy being constant, antidepressant choice is dictated by side effect profile, patient acceptance, and safety. Trazodone has been shown to be safe in overdose, and the side effect profile is mild, with sedation the most common side effect. Sleep electroencephalogram and clinical studies have shown trazodone effective in improving sleep in normal subjects, insomniac patients, and patients with major depression. Tolerance and rapid eye movement rebound on discontinuation do not occur. The 3- to 9-hour half-life of trazodone and its pharmacokinetics favors a dose weighted at bedtime. Studies comparing multiple daytime dosing to single dosing at bedtime have shown equal efficacy in relieving depression. At treatment onset, a single nighttime dose is more productive of sleep with less daytime drowsiness. These differences between single nighttime dosing and multiple daily dosing disappear with continued administration. Geriatric patients respond similarly. Trazodone is best dosed at 150 mg given predominantly (but not necessarily all) at bedtime and increased as needed to 200 to 300 mg for full antidepressant efficacy.

Buspirone in the management of major depression: a placebo-controlled comparison.

One hundred forty outpatients with major depression were admitted to an 8-week, placebo-controlled, double-blind study of buspirone. Entry criteria included a Hamilton Rating Scale for Depression (25-item [HAM-D]) score of greater than or equal to 18 and a Hamilton Rating Scale for Anxiety (HAM-A), score of greater than or equal to 18. A flexible dose schedule ranging from 5-90 mg/day was employed. The mean dose of buspirone was 41-54 mg/day from Week 2 to the end of the study. Sixty-four percent of buspirone patients and 50% of placebo patients were melancholic; 64% of buspirone patients and 74% of placebo patients discontinued treatment before the end of the study. Extender data analysis showed that buspirone patients had significant (p less than .05) HAM-D score reductions compared with the placebo group at Weeks 2, 3, 4, and 6. The HAM-D retardation factor trended toward significance over placebo at Weeks 3, 4, and 6. HAM-D change scores for the subgroup of melancholic patients taking buspirone were significantly (p less than .02) better than those of the placebo-treated melancholic subjects at Weeks 2, 3, 4, and 6. Most other efficacy parameters also favored the buspirone-treated group over the placebo-treated group. The most common adverse experiences for the buspirone group were CNS effects (74% in the buspirone group vs. 21% in the placebo group) and gastrointestinal effects (55% in the buspirone group vs. 37% in the placebo group). Side effects consisted of dizziness, light-headedness, nausea, and headache. No serious or unexpected adverse effects occurred.(ABSTRACT TRUNCATED AT 250 WORDS)

Double-blind, multicenter comparison of sertraline and amitriptyline in elderly depressed patients.

Two hundred forty-one elderly depressed patients entered the 8-week, double-blind phase of this parallel-group, multicenter study; 161 patients were randomized to receive sertraline (50-200 mg/day) and 80 were randomized to receive amitriptyline (50-150 mg/day). Among evaluable patients, there were no statistically significant differences between treatments in any of the primary efficacy variables: change in total Hamilton Rating Scale for Depression (HAM-D) score (17 items), percentage change in HAM-D score, change in HAM-D Item 1, change in Clinical Global Impressions (CGI) Severity score, change in the Depression Factor of the 56-item Hopkins Symptom Checklist, and the CGI Improvement score at the last visit. Similar results were obtained using data from all patients (intention-to-treat analysis), except that amitriptyline was superior in HAM-D Total score (p = .044). The two drugs produced a similar degree of response: on the basis of the HAM-D criterion, 69.4% of sertraline patients and 62.5% of amitriptyline patients responded, and, on the basis of CGI criterion, 79.5% of sertraline and 73.4% of amitriptyline patients responded. Twenty-eight percent of the sertraline patients withdrew from the study because of a treatment-related side effect and 2.5% (4) because of a laboratory abnormality. In comparison, 35% of the amitriptyline patients withdrew because of treatment-related side effects. Sertraline was associated with a statistically lower frequency of somnolence, dry mouth, constipation, ataxia, and pain and a higher frequency of nausea, anorexia, diarrhea/loose stools, and insomnia; thus, anticholinergic effects were less common and gastrointestinal effects were more common with sertraline than with amitriptyline.(ABSTRACT TRUNCATED AT 250 WORDS)

Double-blind, placebo-controlled, fixed dose trial of minaprine in patients with major depression.

Minaprine dihydrochloride is a novel psychotropic drug possessing both antidepressant and psycho-stimulant properties. Prior clinical studies have shown minaprine to be as effective as standard antidepressant agents in the treatment of endogenous depression. The present study examined the safety and efficacy of minaprine at four different doses compared to placebo in 190 outpatients with major depression. Overall, minaprine demonstrated a significant antidepressant action compared to placebo, which was most evident at the maximum dose of 400 mg daily. These data, together with a favorable side effects profile, suggest that minaprine may be an effective antidepressant agent for the treatment of major depression.

United States experience and perspectives with trazodone.

In the United States, trazodone has shown efficacy comparable with tricyclic antidepressants. Trazodone's side-effect profile, however, is vastly superior to the older drugs. In cases of overdose, trazodone alone has not caused a single death. For depressed patients, starting with 150 mg/day of trazodone, preferably at night, produces best results. Preliminary data suggest good safety and efficacy for patients with chronic depression when used up to 5 1/2 years. New uses for trazodone include treatment of insomnia, chronic pain, obsessive-compulsive disorder (OCD), bulimia nervosa, and psychogeriatrics.

Depressive symptoms and intellectual functioning in anxiety patients treated with clorazepate.

The combined data from two 1970s anxiety studies that used clorazepate and placebo as controls were reanalyzed statistically with a focus on intellectual functioning and depressive symptoms. For the 176 patients given either clorazepate or placebo, significant improvement was observed on the mean scores of the intellectual item and the depressive item of the Hamilton Rating Scale for Anxiety; the clorazepate group was significantly more improved than the placebo group. Similar results were observed in patients' self-ratings. The authors conclude that clorazepate is effective in treating depressive symptoms and improving intellectual functioning in patients with generalized anxiety disorder.

A fixed-dose clinical trial of fluoxetine in outpatients with major depression.

Fixed daily doses of 20 mg, 40 mg, or 60 mg of fluoxetine, a highly specific serotonin reuptake inhibitor, were given to 84 depressed outpatients in a double-blind, placebo-controlled, randomized 6-week trial. The 20-mg dose produced improvement of depression in the moderate-severe depression group as expressed in significant reductions of scores on the Hamilton Rating Scale for Depression (p greater than or equal to .007) and the Patient Global Impressions scale (p greater than or equal to .011), and the 20-mg dose caused fewer side effects than did the higher doses. A mildly depressed group of patients showed no improvement at any dose level of fluoxetine.

Treatment of depression in outpatients: a controlled comparison of the onset of action of amoxapine and maprotiline.

In a 4-week double-blind study, amoxapine and maprotiline were compared in the treatment of 76 outpatients with moderate to severe depressive illness. Mean maximum daily dosages were 230 mg for amoxapine and 165 mg for maprotiline. The data suggest that in these dosages amoxapine and maprotiline are equally effective overall. However, significant differences favored amoxapine at Days 4 and 7, in agreement with other studies showing early onset of therapeutic action of amoxapine.

Comparison of alprazolam, imipramine, and placebo in the treatment of depression.

Alprazolam is the first of the triazolobenzodiazepines to be studied in a large population of depressed patients. In a six-week, double-blind multicenter comparison of alprazolam, imipramine hydrochloride, and placebo in the treatment of 723 patients with depression, the two active drugs were statistically more effective than placebo. Alprazolam was at least as effective as imipramine in relieving depressive symptoms, significantly more effective in relieving somatic symptoms, and showed an earlier onset of activity in some measurements. Anticholinergic side effects were reported most often by patients receiving imipramine, while drowsiness was the only side effect reported most often in the alprazolam group. The Feighner Diagnostic Criteria and prestudy and poststudy intercenter conferences with videotaped patient interviews ensured interrater reliability.
