title: The drug treatment of depression in general practice: a comparison of nocte administration of trazodone with mianserin, dothiepin and amitriptyline.
abstract: This 6-week, double-blind, randomised, multicentre study was performed to assess the efficacy and tolerability of evening administration of 150 mg trazodone as an initial and maintenance therapy and to compare this regimen with recommended dosages of mianserin, dothiepin and amitriptyline in the treatment of depressed, adult, general practice patients. A total of 227 eligible depressed patients were recruited into the study by a panel of general practitioners. One hundred and twelve patients were randomised to receive trazodone therapy, 36 received mianserin, 35 received dothiepin and 44 received amitriptyline. Trazodone was administered as a single daily dose of 150 mg. Mianserin was given at a dose of 30 mg for the first 7 days followed by 60 mg daily for the remaining 5 weeks. Dothiepin and amitriptyline were both given at a dosage of 75 mg daily for the 1st week; this was then increased to 150 mg and 100 mg, respectively, for the final 5 weeks of the study. Efficacy of the four treatments was assessed using the modified Hamilton depression rating scale scores and by the Investigator's judgment of both the global severity and improvement of the condition. No significant differences were shown, using any measure of efficacy, between trazodone and any of the three comparator drugs. All treatments resulted in significant improvement in both Ham-D scores and global measures over the period of the study. Using a total side-effect score to assess the incidence and severity of adverse events and adjusting for baseline differences, the four treatments were found to differ.(ABSTRACT TRUNCATED AT 250 WORDS)
