Objective: Few studies exist on pharmacological interventions for adolescents with substance use disorders (SUD). To this end, we evaluated the response of bupropion hydrochloride sustained release (SR) in SUD adolescents with comorbid psychopathology (both attention-deficit/ hyperactivity disorder (ADHD) and a mood disorder).
Methods: Fourteen adolescent outpatients were treated naturalistically and followed openly for 6 months. Adolescents were rated using the Drug Use Screening Inventory--Revised (DUSI-R), ADHD Symptom Checklist, and the Hamilton Rating Scale for Depression (HAM-D). Clinical Global Impression (CGI) Scale scores were obtained for Substance Abuse, ADHD, Anxiety, and Depression. The ratings were completed at baseline, at month 3, and at the 6-month endpoint. Bupropion SR was initiated at 100 mg once-daily and titrated naturalistically to a maximum dose of 400 mg/day.
Results: Of the 14 subjects followed, 13 subjects completed 6 months of treatment. At the 6- month endpoint compared to baseline, treatment with bupropion was associated with clinical and significant reductions in DUSI scores (-39%; p < 0.05), ADHD symptom checklist (-43%; p < 0.001), HAM-D (-76%; p < or = 0.001); and reductions in the CGIs for ADHD (p < or = 0.001), depression (p < or = 0.001), and substance abuse (p < 0.05). The mean daily dose of bupropion SR was 315 mg (in divided doses). No significant adverse events were noted during the follow-up period.
Conclusions: These naturalistic data suggest that bupropion is well tolerated and may be an effective medication for the treatment of substance abusing adolescents with comorbid mood disorders and ADHD.
