| Abstract | Objective: To examine the steady-state pharmacokinetic properties of bupropion sustained release (SR) and their potential developmental differences in youths. Method: Eleven boys and eight girls aged 11 to 17 years old were prescribed bupropion SR monotherapy for attention-deficit/hyperactivity disorder (n = 16) and/or depressive disorders (n = 16). Bupropion SR was given in morning doses of 100 mg/day (n = 11) or 200 mg/day (n = 8) for 14 days or less, with five subjects studied on both doses. All subjects had blood draws from an intravenous port every 1 to 3 hours for 24 hours after their usual morning doses. Pharmacokinetic variables were determined by noncompartmental and compartmental analyses for bupropion and metabolites, respectively. Results: Bupropion and its metabolites exhibited linear pharmacokinetics. Areas under the concentration curves for the hydroxybupropion, threohydrobupropion, and erythrohydrobupropion were 20, 12, and 2.7 times higher, respectively, than for bupropion. Relative to adults, the mean half-lives of bupropion (12.1 hours) and threohydrobupropion (26.3 hours) were significantly shorter, and areas under the concentration curve ratios of metabolites to bupropion were 19% to 80% higher. Conclusions: Youths metabolize bupropion SR faster to hydroxybupropion and other active metabolites than adults. Until the clinical importance of bupropion's metabolites is clarified, bupropion SR should be given in divided doses to youths, as the manufacturer recommends for adults taking higher doses. J. Am.
