QUESTION: In adults with attention deficit hyperactivity disorder (ADHD), is bupropion more effective than placebo?


6 week randomised (allocation concealed*), blinded {clinicians, patients, and outcome assessors}†*, placebo controlled trial.


Psychopharmacology clinic of the Massachusetts General Hospital, Boston, Massachusetts, USA.


40 patients who were 20–59 years of age (mean age 38 y, 55% men) and had ADHD according to DSM-IV criteria. Exclusion criteria were clinically significant chronic medical conditions, history of cardiac arrhythmias or seizures, intellectual impairment (intelligence quotient <75), organic brain disorders, clinically unstable psychiatric conditions, bipolar disorder, drug or alcohol abuse within the past 6 months, or current use of psychotropics. 38 patients (95%) completed the study.


Patients were allocated to 200 mg/day of bupropion (n=21) or placebo (n=19). The dose was titrated up to 200 mg twice daily by week 4.

Main outcome measures

ADHD, depression, and anxiety symptoms were measured using the Clinical Global Impression (CGI) scale, the ADHD Rating Scale, the Hamilton Depression Rating Scale (HDRS), the Beck Depression Inventory (BDI), and the Hamilton Anxiety Rating Scale (HARS). Adverse events were also assessed.

Main results

More patients who received bupropion showed improvement than those who received placebo (score of 1 or 2 [much or very much improved] on the CGI scale, p=0.007; and ≥30% reduction in scores on the DSM-IV ADHD symptom checklist, p=0.02) (table⇓). More ADHD symptoms improved in the bupropion group patients than in placebo group patients (100% v 44% of symptoms, p<0.001). The groups did not differ for scores on the HDRS, the BDI, or the HARS. The groups did not differ for adverse events (table⇓); no serious adverse drug events occurred.

Bupropion v placebo for adults with attention deficit hyperactivity disorder (ADHD) at 6 weeks‡


In adults with attention deficit hyperactivity disorder, bupropion was more effective than placebo in improving symptoms and did not produce severe adverse effects.


The study by Wilens et al shows that bupropion may be a valuable option for the treatment of ADHD. For patients who pose reservations or clear contraindications to the use of stimulants, such as comorbid substance abuse, depression, or anxiety disorders, the availability of bupropion could be an important breakthrough in their management.1 Bupropion should be easier to comply with than stimulants (once/day dosage and modified release forms), although a better understanding of the side effect profile might add to this case. Unfortunately, in this study, those groups were excluded and therefore the efficacy of bupropion in those patients remains open to debate and further investigation.

The method of recruitment of participants introduces a degree of selection that could also impinge upon the study's generalisability, because most of the patients were either volunteers or referrals to a specialist service and were from relatively high socioeconomic strata. The number of potential patients was dramatically reduced after the population screening (74%), which was probably because of comorbidity. Although no severe adverse effects were reported in the study, 5 patients (25%) from the bupropion group needed a dose reduction because of adverse events, and 2 (10%) dropped out as non-compliant. Furthermore, 43% of those who responded to bupropion decided not to continue with the treatment once the study had ended, which may be relevant to the patient's degree of satisfaction with the drug.

It is becoming clear that bupropion may have its own niche within the therapeutic options for ADHD, but insufficient evidence currently exists to advocate its widespread use conclusively. More trials are needed to ratify the therapeutic validity of bupropion as an alternative treatment to the stimulants, not only in adults but also in younger patients. Future trials should include patients with comorbid substance misuse, depression, or anxiety disorders, where an alternative treatment to the stimulants could be of real benefit.2


Concerns have been raised regarding the development of tics in some children with attention-deficit hyperactivity disorder (ADHD) receiving stimulants. Because in many patients with Tourette's syndrome (TS) the ADHD symptoms are the major source of disability, alternative nonstimulant treatments are needed. Initial reports on bupropion have suggested that it may be an effective alternative in children and adults with ADHD. The value of bupropion as an alternative treatment for patients with comorbid TS and ADHD is determined by the question of association with exacerbation of tics. The purpose of this study was to examine an apparent association with exacerbation of tics in patients with comorbid TS and ADHD. A careful retrospective analysis was conducted of clinic cases of patients who all had comorbid TS and ADHD treated with bupropion. We present four cases of children with ADHD and comorbid TS treated with bupropion in whom tics were exacerbated by this medicine. This series suggests that bupropion may not be an appropriate alternative to stimulants in the treatment of ADHD in TS.
