title: A differential response to nortriptyline and fluoxetine in melancholic depression: the importance of age and gender.
abstract: OBJECTIVE
  To consider the impact of age and gender on the antidepressant response to nortriptyline and fluoxetine in melancholic depression.
  
  
  METHODS
  Of 191 depressed patients, 113 met study criteria for melancholia. All patients were randomized to receive either fluoxetine or nortriptyline. Response rates, defined as an improvement of 60% or more on the Montgomery Asberg Depression Rating Scale over 6 weeks of antidepressant treatment on an intention to treat basis, were examined by age, and by age and gender.
  
  
  RESULTS
  Melancholic depressed patients 40 years or older, especially men, had a markedly superior response to nortriptyline compared with fluoxetine. Conversely, melancholic depressed patients, age 18-24 years, especially women, had a markedly superior response to fluoxetine.
  
  
  CONCLUSIONS
  Age and gender appear to be critical variables in understanding differential antidepressant responses to tricyclic antidepressants and selective serotonin reuptake inhibitors in melancholic depression.
