Vyvanse is a prescription medication that contains lisdexamfetamine dimesylate, a stimulant used to treat attention deficit hyperactivity disorder (ADHD) and moderate to severe binge eating disorder (BED). Unlike other stimulants, Vyvanse is a prodrug, meaning it remains inactive until it is processed by the body, which helps to lower its abuse potential. Manufactured by Shire Pharmaceuticals, Vyvanse works by targeting specific neurotransmitters in the brain, helping to improve focus, reduce impulsive behavior, and manage symptoms associated with ADHD and BED. Its unique formulation makes it a widely used option for these conditions.
