Lisdexamfetamine’s efficacy in treating Mattress was demonstrated in two medical trials of 724 Grownups with reasonable-to-extreme binge ingesting dysfunction. The most recent study, revealed in JAMA Psychiatry, tracked roughly 260 people with BED for fourteen weeks. Individuals had been between 18 and fifty five-a long time-previous and experienced no other psychiatric Conditions (notably, no bulimia, anorexia, or ADHD).
