Double‐blind study of the efficacy and safety of milnacipran and imipramine in elderly patients with major dipressive episode

Abstract
The novel antidepressant agent milnacipran is a dual and equipotent serotonin and noradrenaline reuptake inhibitor. The aim of this double‐blind study was to compare the efficacy and safety of milnacipran (50 mg twice daily) with that of imipramine (50 mg twice daily) in elderly patients with major depressive episode. A total of 219 patients were randomly assigned to 8 weeks of double‐blind treatment with either milnacipran or imipramine; 72 patients withdrew from the study. At the end of treatment no significant differences were found between milnacipran and imipramine in antidepressant efficacy. A significantly greater number of side‐effects, particularly anticholinergic effects, was observed in the imipramine group. Milnacipran may be preferable to imipramine in elderly depressed patients, as it provides the same antidepressant activity as imipramine with a lower incidence of side‐effects, and does not impair cognitive ability.
