Response to desipramine treatment in adolescent depression: a fixed-dose, placebo-controlled trial.
OBJECTIVE
To determine the efficacy and tolerability of the tricyclic antidepressant desipramine (DMI) in the treatment of DSM-III-R-diagnosed major depressive disorder in adolescents.


METHODS
Sixty adolescents (42 female, 18 male; aged 15 to 19 years) diagnosed with major depressive disorder using clinical interview and Schedule for Affective Disorders and Schizophrenia for School-Age Children were randomized to receive either DMI (200 mg daily in divided doses) or placebo for six consecutive weeks following a 1-week placebo period. Treatment outcome was determined using the Hamilton Depression Rating Scale and the Beck Depression Inventory. Tolerability was determined using a symptom side effects scale. In addition, a variety of laboratory and cardiovascular monitoring was performed.


RESULTS
No significant differences in treatment outcome between DMI- and placebo-treated groups were determined. Neither DMI, nor its metabolite 2-hydroxy-DMI, nor their ratio, was positively correlated to treatment outcome. The DMI group endorsed more side effects but there were no significant between-group differences in any laboratory, electrocardiographic, or other cardiovascular parameters apart from heart rate, which was increased in the DMI-treated group (p = .03).


CONCLUSIONS
Given the findings of this study and our review of previously published reports of tricyclic antidepressant treatment in this population, the routine use of short-term (6 weeks) DMI in the treatment of adolescent depression is not supported by the data on hand. Further investigations into what constitutes optimal psychopharmacological treatment of adolescent depression are warranted.
