Paroxetine versus nortriptyline in the continuation and maintenance treatment of depression in the elderly.
Elderly depressed patients are vulnerable to recurrence of depression and benefit from long-term antidepressant therapy. Physicians increasingly use selective serotonin re-uptake inhibitors (SSRIs) as maintenance therapy, although in the absence of data showing that SSRIs are as efficacious as tricyclic antidepressants (TCAs) in the prevention of depression relapse and recurrence. Our objective was to evaluate, in an open trial, the efficacy of paroxetine versus nortriptyline for preventing recurrence of depression in the elderly. Elderly patients with major depression were randomly assigned in a double-blinded fashion to receive either paroxetine or nortriptyline for the acute treatment of depression. Patients who did not respond or tolerate their assigned medications were crossed over openly to the comparator agent. Patients whose depression remitted continued antidepressant medication (paroxetine n = 38; nortriptyline n = 21) during an open 18-month follow-up study. We examined the rates of and times to relapse and to termination of treatment for any reason. Paroxetine (PX) and nortriptyline (NT) patients had similar rates of relapse (16% vs. 10%, respectively) and time to relapse (60.3 weeks vs. 58.8 weeks, respectively) over 18 months. A lower burden of residual depressive symptoms and side effects during continuation and maintenance treatment was evident in nortriptyline-treated patients. Paroxetine and nortriptyline demonstrated similar efficacy in relapse and recurrence prevention in elderly depressed patients over an 18-month period.
