Pharmacological treatment of attention deficit hyperactivity disorder with co-morbid drug dependence

Abstract

Background: Drug dependence is frequent in patients with attention deficit hyperactivity disorder (ADHD). Nevertheless, the efficacy and safety of pharmacological treatments in this population are unclear. Methods: A systematic review with meta-analysis was performed. Randomised placebo-controlled clinical trials investigating the efficacy of pharmacological treatment in patients with co-occurring ADHD and substance use disorder (SUD) were included. ADHD symptom severity, drug abstinence and all-cause treatment discontinuation were the primary study endpoints. The effects of patient-, intervention- and study-related covariates over the primary outcomes were investigated by means of meta-regression. Results: Thirteen studies were included, enrolling a total of 1,271 patients. A small to moderate reduction of ADHD symptoms was found. Meta-regression analysis identified the presence of a lead-in period as a covariate associated with reduced efficacy. Conversely, no beneficial effect was observed either on drug abstinence or treatment discontinuation. The efficacy on ADHD symptoms was smaller in studies with a lead-in period. A positive correlation between the efficacy for ADHD and that for SUD was found. Conclusions: The efficacy of pharmacological interventions for co-occurring ADHD and SUD has been little investigated. Mixed results were obtained: while pharmacological interventions improved ADHD symptoms, no beneficial effect on drug abstinence or on treatment discontinuation was noted. The strength of the recommendation of pharmacological treatment for co-occurring ADHD and SUD is therefore modest. The study was registered with the international prospective register of systematic reviews (PROSPERO): CRD 4212003414.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
