title: Paroxetine in the treatment of elderly depressed patients in general practice: a double-blind comparison with amitriptyline.
abstract: A total of 101 patients entered a double-blind, parallel-group study in general practice, comparing the efficacy and tolerability of paroxetine and amitriptyline in elderly depressed patients. All patients received placebo for 1 week followed by active therapy for a total of 6 weeks. Medication was randomly allocated, two-thirds of the patients took paroxetine (20 mg daily) and one-third received amitriptyline (50 mg daily); this dose was increased to 30 mg and 100 mg, respectively, after 1 week. Of the patients who entered the placebo run-in, 90 took active treatment and were evaluable on an intention-to-treat basis (56 paroxetine, 32 amitriptyline). The mean age of the patients was 72 years. Significant reductions in Hamilton Depression Rating Scale (HAMD) from baseline to the end of treatment were seen for both groups (p < 0.01), with no difference between treatments. The HAMD score was reduced by half, or more, for 76% of patients taking paroxetine and 86% taking amitriptyline. Significant improvement was observed in the investigators' Clinical Global Impression (CGI) score for 57% of patients taking paroxetine and 52% on amitriptyline. Improvements after treatment were also observed in the Leeds Sleep Evaluation Questionnaire (LSEQ) scores. Significantly fewer patients taking paroxetine reported adverse events (34% vs 63% taking amitriptyline, p = 0.02). Those taking paroxetine experienced significantly fewer anticholinergic side effects (7% vs 25% taking amitriptyline, p = 0.04). Overall, this study confirmed the effectiveness of paroxetine as an antidepressant drug.(ABSTRACT TRUNCATED AT 250 WORDS)
