A double‐blind controlled clinical trial comparing fluvoxamine with imipramine.

Abstract

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.
