Comparison of sertraline and nortriptyline in the treatment of major depressive disorder in late life.

Abstract

This study was designed to evaluate the comparative efficacy and safety of sertraline and nortriptyline for the treatment of major depressive disorder in older adults. A double-blind, parallel group design was used to compare 210 outpatients, 60 years of age and older, who met DSM-III-R criteria for major depressive episode and had a minimum Hamilton Depression Rating Scale score of 18. The patients were randomly assigned to 12 weeks of treatment with either sertraline (50-150 mg/day) or nortriptyline (25-100 mg/day). The safety profiles of the two treatments were similar except that nortriptyline treatment was associated with a significant increase in pulse rate, whereas sertraline was associated with a nonsignificant decrease. Efficacy of both drugs was similar for both treatments at all time points, with 71.6% (N=53 of 74) of the sertraline-treated patients and 61.4% (N=43 of 70) of the nortriptyline-treated patients achieving responder status by week 12. Time to response was also similar, with more than 75% of the improvement in scores on the Hamilton depression scale having occurred by week 6. Secondary efficacy measures (posttreatment measures of cognitive function, memory, and quality of life) revealed a significant advantage for sertraline treatment. Primary efficacy measures showed sertraline and nortriptyline to be similarly effective. With secondary outcome measures there was consistent evidence of an advantage for the sertraline-treated group. The clinical impact of these measures on the long-term well-being of elderly depressed patients should be examined in a study of maintenance treatment.
