Acute and chronic administration of trazodone in the treatment of disruptive behavior disorders in children.

We report the results of an open trial of trazodone in the treatment of severe behavioral disturbances in a sample of 22 hospitalized children previously found to be unresponsive to other treatments. Response to treatment was assessed by overall clinical criteria and improvements in individual symptom dimensions during the inpatient hospitalization. Thirteen children (67%) were found to benefit from the introduction of trazodone. Aggressive, impulsive behaviors were symptoms most frequently improved by this agent. Three of those found to be nonresponders actually worsened in symptomatology. A follow-up interview of the parents was conducted 3-14 months after discharge from the inpatient unit, for those children who initially responded to trazodone administration. The results of this interview suggest that the effect of trazodone was persistent for a prolonged period of time after the initial inpatient trial. Trazodone appears to be of value in the management of severe behavioral disturbances in children. The possible mechanism of action of trazodone is discussed.
