Clinical activity and tolerability of trazodone, mianserin, and amitriptyline in elderly subjects with major depression: a controlled multicenter trial.

The aim of this multicenter study was to compare trazodone (TRA) with two reference drugs, amitriptyline (AMI) and mianserin (MIA), under double-blind conditions, in an elderly population, to ascertain age-related patterns for efficacy and tolerability. One hundred six elderly depressed inpatients, ranging in age from 60 to 83 years, diagnosed as having major depression according to DSM-III, were treated with 75 mg AMI (37 patients), 60 mg MIA (33 patients) or 150 mg TRA (36 patients) p.o.t.i.d. for 5 weeks. There were no differences in the clinical outcome among the three groups of patients at the end of the trial, with a significant amelioration (p less than 0.01) for the Hamilton Rating Scale for Depression (HRS-D) and the Geriatric Depression Scale (GDS). TRA showed a lower overall prevalence of side effects than AMI or MIA, particularly for anticholinergic (p = 0.03 vs. AMI) and cardiovascular (p = 0.05 vs. MIA) effects. For these data GDS seems to be most reliable in detecting changes in elderly depressive symptomatology; moreover a comparable therapeutic response (among the three drugs) but a better tolerance for atypical antidepressants, particularly TRA, make advisable the use of the latter drug in the elderly population.
