Long-term therapy for depression with trazodone

Trazodone and imipramine were compared in a two-center double-blind study of moderately to severely depressed outpatients. Results for 44 patients who have completed the 12-month comparison showed superior efficacy of trazodone at endpoint on all efficacy measures. Significant differences were also seen on individual Hamilton Depression Rating Scale items, with lower anxiety scores at 5 evaluation points for the trazodone group. Clinical Global Impressions ratings also favored trazodone treatment. Anticholinergic effects and tremor were significantly more frequent in imipramine-treated patients, whereas drowsiness was more frequent with trazodone. No significant changes were seen in blood pressure or ophthalmologic exams; 2 trazodone patients and 1 imipramine patient developed slight ECG changes during therapy; these may have been age-related. Continued clinical benefit has been seen in 12 patients who have received open-label trazodone for additional periods of up to 3 years. These findings show trazodone to be clearly effective in long-term treatment of moderate to severe depression; the drug may be of particular benefit when atropine side effects pose serious problems, as in the elderly and patients with cardiovascular disorders.     

Trazodone, a new antidepressant: efficacy and safety in endogenous depression.

The effectiveness of trazodone was assessed over a 4-week period under double-blind conditions. Twenty-eight inpatients with a diagnosis of endogenous depression received either trazodone, imipramine, or placebo. Trazodone was significantly better than placebo and frequently better than imipramine according to analyses of the results of the Hamilton Psychiatric Scale for Depression, severity of illness and clinical global improvement ratings, and the Global Ward Behavior Scale. Significant improvement was evident in the trazodone group by the end of the first week of therapy, particularly in those symptoms associated with depression and accompanying anxiety. There were fewer side effects with trazodone than with imipramine.     

A comparison of the effects of trazodone and amitriptyline on skills performance by geriatric subjects

Fifteen healthy adults, aged 60 years and older, participated in a double-blind, crossover study of trazodone in comparison with amitriptyline and placebo. A battery of laboratory tests was used to measure drug effects on information processing, attention, and visual-motor skills. Amitriptyline 50 mg impaired vigilance and tracking performance and increased drowsiness. Trazodone 100 mg impaired only the most difficult tracking task. This study demonstrates that cognition and performance are less adversely affected in geriatric subjects by trazodone than by amitriptyline beginning 90 minutes after a single-dosage trial.     

A combination of hypothalamic phospholipid liposomes with trazodone for treatment of depression. An open controlled study

In an open controlled trial of 48 patients with major depression illness (according to DSM-III), the patients were randomly assigned to 2 groups. One group of 25 patients was treated with 200-300 mg/day of trazodone and a second group of 23 patients was treated with 200-300 mg/day trazodone plus 1 ampoule (corresponding to 1000 gamma of lipidic phosphorous) twice daily of hypothalamic phospholipids (HPL). The effectiveness of treatment was evaluated by the Hamilton Rating Scale for Depression (HRSD). Side effects of treatment with trazodone were looked for by measuring systolic and diastolic blood pressure and heart rate and from EEG made before and on the 7th and 30th days of treatment. Combination with HPL shortened the typical latency of action of the antidepressant trazodone, definitely improved the subjective symptoms, especially the psychosomatic symptoms, on the HRDS and decreased the incidence of such side effects of trazodone as hypertension, reflex tachycardia and asthenia.

Fluoxetine versus trazodone in the treatment of outpatients with major depression

Fluoxetine and trazodone were compared in a double-blind, randomized, parallel, 6-week trial in 43 outpatients with major depression after a 1-week single-blind placebo period. Thirty-five patients completed at least 3 weeks of active medication, while 25 patients completed all 6 weeks. Response rates, whether defined by end-of-treatment Hamilton Rating Scale for Depression (HAM-D) score less than 10 or by a 50% reduction in HAM-D scores, were equivalent for the two medications. For fluoxetine, HAM-D scores were significantly lower at Weeks 1 and 2 compared with those of trazodone. Trazodone improved sleep significantly more than fluoxetine. Fluoxetine was associated more frequently with weight loss (p = .002) and less frequently with dizziness (p = .04) than trazodone.     

The effects of trazodone on sleep in patients treated with stimulant antidepressants

BACKGROUND AND PURPOSE: To evaluate the effects of trazodone on subjective and objective measures of sleep in depressed insomnia patients treated with selective serotonin reuptake inhibitors (SSRIs). SSRIs can exacerbate or cause new insomnia while alleviating other symptoms of depression. Trazodone has been reported to be an effective hypnotic for patients with antidepressant-associated insomnia. PATIENTS AND METHODS: Twelve female patients were given either 100 mg trazodone or placebo for 7 days in a double-blind crossover design with a 7-day washout period. Polysomnographic recordings were repeated on the 3rd, 9th and 17th, 23rd nights after treatment with trazodone or placebo. Sleep was assessed by Pittsburgh sleep quality index (PSQI) at the beginning and end of the study. Psychological evaluation was done by Hamilton depression rating scale (HDRS). RESULTS: Trazodone significantly increased total sleep time, percentage of stages 3+4, sleep efficiency index, sleep continuity index and decreased percentage of stage 1, number of awakenings, stage shifts compared to the baseline. This improvement was also obtained after 7 days of treatment. The PSQI score was reduced to 5+/-1.6 at the end of the study. HDRS was reduced to 11.5+/-4.5 with trazodone and to 12.2+/-3 with placebo. CONCLUSION: Trazodone is effective in the treatment of antidepressant-associated insomnia.     

A double-blind, multicentre study to assess the tolerability and efficacy of paroxetine compared with amitriptyline in the treatment of depressed patients in Australian general practice.

OBJECTIVE: This study compared the tolerability and efficacy of paroxetine and amitriptyline in the treatment of depression in general practice. METHODS: In this double-blind, multicentre study conducted in the general practice, patients with depression (Montgomery Asberg Depression Rating Scale [MADRS] score > or = 20) who were regarded as requiring antidepressant therapy were randomly assigned to receive paroxetine (20 mg, n = 184) or amitriptyline (50-100 mg, n = 191) once daily for 9 weeks. RESULTS: More patients completed treatment with paroxetine than with amitriptyline (71.1% vs 56.1%, p = 0.009). Depression rating scores (MADRS and Clinical Global Impression [CGI]) were improved with both agents, but at week 9, paroxetine achieved more favourable scores compared with amitriptyline on MADRS (p=0.019), CGI severity of depression (p=0.044), and CGI efficacy index (p = 0.038). CONCLUSIONS: Depressed patients treated in general practice respond more quickly and are more likely to complete the treatment regimen with paroxetine than with amitriptyline.     

Survey on the usefulness of trazodone in patients with PTSD with insomnia or nightmares

BACKGROUND: Trazodone is commonly used in the treatment of insonmia and nightmares in patients with PTSD. There is little evidence in the literature for this practice. METHOD: Seventy-four patients from the Palo Alto Veterans Affairs Health Care System in California who were admitted to a specialized 8 week inpatient treatment program for PTSD were surveyed regarding their use of trazodone in the treatment of insomnia or nightmares. Patients were asked to complete a questionnaire regarding trazodone's effectiveness, side effects, and optimal doses. RESULTS: Of 74 patients surveyed, 60 patients were able to maintain an effective dose of trazodone. The other 14 patients were unable to tolerate the medication. Seventy-two percent of the 60 patients assessed found trazodone helpful in decreasing nightmares, from an average of 3.3 to 1.3 nights per week (p<.005). Ninety-two percent found it helped with sleep onset, and 78% reported improvement with sleep maintenance. There was a significant correlation between the effectiveness in decreasing nightmares and improving sleep (r= .57, p < .005). The effective dose range of trazodone for 70% of patients was 50 to 200 mg nightly. Of the 74 patients surveyed, 9 (12%) reported priapism. CONCLUSION: Trazodone appears effective for the treatment of insomnia and nightmares associated with chronic PTSD. However, controlled trials are needed before any definite conclusions can be drawn. The higher than expected occurrence of priapism warrants clinicians asking directly about this side effect.     

Femoxetine and amitriptyline in general practice: a randomized double-blind group comparison

Patients with a depressive illness with 4 major symptoms of depression and a score of at least 17 on the Hamilton Depression Scale (1-17) (HDS) were allocated to a randomized double-blind group comparative study in general practice. After retrospective analysis, all 81 patients except one were characterized as suffering from a 'Definite Major Depressive Disorder', as defined by Spitzer et al. (1978). After 6 weeks of treatment with a daily dosage of 600 mg femoxetine or 150 mg amitriptyline, no statistically significant differences between the 2 treatment groups were observed, either when using the HDS or the clinical global assessment scale. Confidence limits of 95% for differences between therapeutic effect showed a non-significant tendency in favour of amitriptyline. During treatment, there were statistically significant differences in the reduction of HDS score between the 2 treatments in week 2. These differences were the result of amitriptyline's significantly greater effect on the 3 sleep items at week 2, as indicated by the results of single item analysis. Drop out rates due to side effects were between 14-15% in both treatment groups. Of the patients treated with femoxetine, 38% experienced no side effects, compared to 14% of patients treated with amitriptyline. Nausea was the side effect most commonly reported by patients treated with femoxetine, whereas a significantly greater frequency of anticholinergic side effects was recorded during treatment with amitriptyline (P less than 0.05). Unlike amitriptyline, femoxetine did not increase body weight. Treatment with the active drug was continued after the trial period in 14 and 18 patients in the femoxetine and amitriptyline groups respectively.

Trazodone-oral cocaine interactions

Depression and dysphoria can follow the long-term use of cocaine. Little is known about the interaction of antidepressant drugs with cocaine and similar stimulants in humans. The physiologic and subjective effects of an oral 2-mg/kg dose of cocaine hydrochloride were measured in eight healthy cocaine-using men after pretreatment with a single, 100-mg oral dose of the triazolopyridine antidepressant trazodone hydrochloride or placebo in a double-blind study. The cocaine-induced effects of increased BP, increased pupil size, and decreased skin temperature were diminished by trazodone pretreatment. Trazodone alone did not alter plasma epinephrine or norepinephrine levels. An increase in plasma epinephrine levels after cocaine administration was not altered by trazodone pretreatment, but the increase in the norepinephrine level was larger. Trazodone alone produced mild sleepiness. Cocaine-induced euphoria was not altered by trazodone pretreatment, although feelings of tension and shakiness after cocaine administration were diminished.     

A double-blind multicentre comparison of mirtazapine and amitriptyline in elderly depressed patients

Hnyberg OJ, Maragakis B, Mullin J, Norum D, Stordall E, Ekdahl P, Ose E, Moksnes KM, Sennef C. A double-blind multicentre comparison of mirtazapine and amitriptyline in elderly depressed patients. Acta Psychiatr Scand 1996: 93: 184–190. © Munksgaard 1996. A total of 115 elderly patients (60–85 years of age) with DSM III diagnosis of major depressive episode were randomly assigned to 6 weeks of treatment with either mirtazapine, 15–45 mg/day, or amitriptyline, 30–90 mg/day. Efficacy was assessed biweekly, using tbe Hamilton Rating Scale for Depression (HRSD) and Montgomery and Åsberg Depression Rating Scale (MADRS) as primary outcome variables. The treatment with both drugs resulted in a similar reduction of total HRDS and MADRS scores, with no statistically significant differences between treatment groups at any assessment point or at endpoint. Statistically significant differences favouring amitriptyline were present according to CGI-Global Improvement Scale at endpoint, HRDS cognitive disturbance factor at weeks 2, 4 and 6 and endpoint and retardation factor at week 6. Adverse events were reported by a similar number of patients in both treatment groups. Additional research is needed to assess further the efficacy and tolerability of mirtazapine among elderly depressed patients.     

Tianeptine and amitriptyline. Controlled double-blind trial in depressed alcoholic patients

129 chronic alcoholic patients, withdrawn from alcohol and presenting major depression or dysthymic disorder, were treated for 4-8 weeks under double-blind conditions either with a new antidepressant, tianeptine (37.5 mg per day), or with amitriptyline (75 mg per day). Both groups presented steady improvement of the symptoms of depression during treatment, as scored on the Montgomery and Asberg Depression Rating Scale and the Hopkins Symptom Checklist self-evaluation; for the latter scale, the improvement was significantly greater in the tianeptine group. In addition to the improvement of mood, tianeptine also produced significant reduction of the somatic complaints of the depressed patients. Furthermore, tianeptine possesses anxiolytic activity, as shown by the change of the Hamilton Anxiety Rating Scale global score, similar to that produced by amitriptyline. The anxiolytic activity of tianeptine was not accompanied by any impairment of vigilance, unlike that of amitriptyline. Tianeptine produced rare, mild anticholinergic effects. The results obtained show that tianeptine is an effective anxiolytic antidepressant, with better safety than amitriptyline, suitable for use in the treatment of mood disorders following alcohol withdrawal.     

Treatment of neuroleptic-induced akathisia with the 5-HT2A antagonist trazodone

Akathisia is a common and distressful extrapyramidal adverse side effect usually resulting from the use of antipsychotic medications. Early management of akathisia is important because it may be associated with poor treatment response and medication noncompliance. Unfortunately many patients fail to respond to standard management of akathisia. In addition to dopaminergic mechanisms, it has been hypothesized that serotonin may play a prominent role in the pathophysiology of akathisia. Trazodone is an antidepressant agent demonstrating prominent serotonergic antagonistic properties. This open-label pilot study investigates the efficacy of trazodone in the management of akathisia. Nine female patients with a score of at least "mild akathisia" on the Barnes Akathisia Scale, and receiving a stable dose of antipsychotic medication, were administered trazodone, titrated up to a dosage of 100 mg/day over a period of 5 days. The patients demonstrated marked improvement in symptoms of akathisia. In addition, some improvement was noted in symptomatology of anxiety, depression, and psychosis. These observations suggest the use of trazodone as a beneficial and relatively safe medication for the treatment of antipsychotic medication-induced akathisia. Further study in the context of a double-blind, placebo-controlled trial is mandated to substantiate these preliminary findings.     

A comparative trial of fluoxetine versus trazodone in outpatients with major depression

The effectiveness of fluoxetine as an antidepressant was contrasted with trazodone in a 6-week double-blind trial in 40 patients. The total score on the Hamilton Rating Scale for Depression and the global improvement score on the Clinical Global Impressions scale favored trazodone at the end of 3 weeks of treatment. However, that difference was no longer apparent during the remainder of the study. The authors hypothesize that fluoxetine 20 mg/day may be an ineffective dosage of the drug or that fluoxetine has a slower onset of antidepressant action than does trazodone.     

A double blind comparison of alprazolam and amitriptyline hydrochloride in the treatment of nonpsychotic depression

In a six week, double-blind, parallel study of alprazolam and amitriptyline hydrochloride in 130 outpatients suffering from moderate to severe nonpsychotic depression, alprazolam was as effective as amitriptyline hydrochloride in relieving depressive symptoms and significantly more effective in relieving symptoms of anxiety and somatization. Alprazolam showed an earlier onset of activity in most measurements of efficacy and produced fewer side effects than amitriptyline hydrochloride. Anticholinergic side effects were reported more frequently by patients taking amitriptyline hydrochloride, while drowsiness was reported more frequently by patients taking alprazolam. At the end of the study, the average daily doses were 2.4 mg alprazolam and 135 mg amitriptyline hydrochloride. The Hamilton Psychiatric Rating Scale for Depression, Hamilton Anxiety Rating Scale, Physician's Global Impressions, Patients' Global Impressions, Hopkins Self-Rating Symptom Scale, and Symptom and Side Effects Checklist were evaluated at the end of weeks 1, 2, 3 and 6 to determine and compare the efficacy and safety of the two study drugs.     

Amitriptyline in the treatment of headache in patients with Parkinson's disease: a double-blind placebo-controlled study

We evaluated the effect of 25 mg bid amitriptyline on muscle contraction headache in 36 patients with Parkinson's disease in a randomized double-blind placebo-controlled study. Treatment lasted 12 weeks, and we assessed the efficacy by number of days with headache, sum-of-severity score (intensity X number of days with headache), and consumption of analgesics. We also administered Hoehn-Yahr staging, the Webster Rating Scale, the Mini-Mental State, and the Zung Self-Rating Depression Scale. We assessed the patients after a 4-week run-in period and after 4, 8, and 12 weeks of treatment. Thirty-one patients (15 in the amitriptyline group and 16 in the placebo group) completed the trial. Amitriptyline reduced the intensity and the frequency of headache, whereas the placebo did not. The Zung Depression Scale and the Webster Rating Scale findings remained unchanged.
