title: Antidepressant efficacy of sertraline and imipramine for the treatment of major depression in elderly outpatients.
abstract: BACKGROUND
  Most double-blind studies of efficacy and tolerability of sertraline as compared to tricyclics in the treatment of late-life major depression have used amitriptyline as a standard, leading to the inevitable conclusion that the former drug is better tolerated than the latter, with both being equally efficacious.
  
  
  OBJECTIVE
  To compare the antidepressant efficacy and tolerability of sertraline (50 mg/day) and imipramine (150 mg/day) in the first 6 weeks of the treatment of major depression in the elderly.
  
  
  METHODS
  A randomized double-blind parallel study with 6 weeks of follow-up.
  
  
  METHODS
  The psychogeriatric clinic at the Institute of Psychiatry, Hospital das Clínicas, Faculty of Medicine of the University of São Paulo.
  
  
  METHODS
  55 severe and moderately depressed non-demented outpatients aged 60 years or more.
  
  
  METHODS
  Patients were assigned to sertraline 50 mg/day or imipramine 150 mg/day.
  
  
  METHODS
  CAMDEX interview. Psychiatric diagnosis followed the guidelines for "Major Depressive Episode" according to DSM-IV criteria. Severity of symptoms was evaluated using the "CGI" and "MADRS" scales. Cognitive state was assessed using the Mini-Mental State Examination. Side effects were assessed using the "Safetee-Up" schedule.
  
  
  RESULTS
  Both groups had a significant decrease in depressive symptoms according to the MADRS scores after 6 weeks of treatment (P = 0.01). No significant differences between groups were detected regarding treatment outcome (t = 0.4; P = 0.7). Although the dropout rate was greater in the imipramine group, the overall tolerability among patients who completed the 6-week trial was similar in both test groups.
  
  
  CONCLUSIONS
  Both sertraline and imipramine exhibited good efficacy and an acceptable side-effect profile for elderly depressed patients after 6 weeks of antidepressant treatment.
