Lisdexamfetamine Dimesylate, Attention Deficit Disorder with Hyperactivity, Binge-eating Disorder, ReviewAbstract
Introduction: Lisdexamfetamine (LDX) is a medication indicated for the treatment of Attention Deficit Hyperactivity Disorder (ADHD) and Binge Eating Disorder (BED). After oral administration, the medication is rapidly absorbed by the gastrointestinal tract and converted into D-amphetamine covalently bound to the natural amino acid L-lysine, responsible for the drug’s activity. Objective: To evaluate the long-term effectiveness of Lisdexamfetamine for treating Attention Deficit Hyperactivity Disorder and Binge Eating Disorder. Method: A search was conducted in PubMed, Embase, Web of Science, and Cochrane using descriptors and their respective synonyms to identify the long-term efficacy and safety of LDX in individuals with ADHD and BED. Interventional and controlled group studies with a follow-up period of more than 5 weeks were included. Results: 30 studies were included. Regarding the population, the effects of LDX were investigated in individuals aged 5-55 years, with the longest follow-up being 108 weeks. Overall, the literature indicates a significant reduction in symptoms within the first 5-6 weeks of treatment, stabilizing in the following weeks. For ADHD, studies up to 108 weeks reported mean reductions of –25.8 points on the ADHD-RS-IV (95% CI –27.0 to –24.5), improvement in CGI-I ratings from 42.3% to 89.1%, and maintenance-of-response rates above 75% in adults after 12 months. For BED, studies with up to 52 weeks of follow-up showed that 89.8% of participants experienced clinical improvement on the CGI-I, with significant reductions in weekly binge-eating days (least-squares mean differences up to –1.66; p < 0.001) and a mean improvement of –1.95 points on the EDE-Q. Conclusions: The findings suggest that LDX shows promising long-term results for both health conditions. However, healthcare professional follow-up is necessary due to the drug’s adverse events.
