Abstract
OBJECTIVE: This study compared the efficacy, tolerability, and safety of paroxetine and nortriptyline in depressed patients with ischemic heart disease. METHOD: After a 2-week, single-blind placebo lead-in phase, 81 outpatients with DSM-III-R-defined nonpsychotic unipolar major depression and ischemic heart disease were randomly assigned to double-blind treatment with paroxetine or nortriptyline for 6 weeks. Paroxetine was administered at a fixed-flexible dose of 20–30 mg/day. Nortriptyline dose was adjusted with the use of blood-level monitoring to reach a plasma concentration of 50–150 ng/ml. RESULTS: Twenty-seven of the 41 patients who started treatment with paroxetine and 29 of the 40 patients who started treatment with nortriptyline had an improvement of at least 50% in their Hamilton Depression Rating Scale scores. Significantly more patients taking nortriptyline discontinued treatment prematurely (35% versus 10%), and more patients taking nortriptyline had adverse events resulting in termination (25% versus 5%). CONCLUSIONS: Both treatments were efficacious. Sixty-three percent of all patients improved at least 50%, and of these, 90% met the criteria for remission. Paroxetine was better tolerated than nortriptyline and less likely to produce cardiovascular side effects.
