Objective:
To determine amitriptyline's (AMI) efficacy in the acute treatment of adolescent major depressive disorder (MDD).
Method:
Subjects aged 12 through 17 years meeting Research Diagnostic Criteria for MDD, diagnosed with the Schedule for Affective Disorders and Schizophrenia for School-Age Children (K-SADS), participated in a 2-week placebo-washout followed by an 8-week, randomized, double-blind, parallel-design, placebo-controlled trial of AMI, 5 mg/kg per day. The K-SADS nine-item scale, the Hamilton Depression Rating Scale, and the Clinical Global Impressions rating scale were used as outcome measures.
Results:
Thirty-one subjects were randomized (18 AMI, 13 placebo). Twenty-two subjects were study completers (12 AMI, 10 placebo). AMI's efficacy was suggested by the Clinical Global Impressions but not the K-SADS-derived data. Perhaps the primary limitation of the current study is its small sample size.
Conclusion:
No definitive recommendation can be made regarding the efficacy of tricyclic antidepressants in the treatment of adolescent MDD.
