Lisdexamphetamine (L-lysine-D-amphetamine; sold as Vyvanse) is a psychostimulant prodrug of the phenethylamine and amphetamine chemical classes. Its molecular structure consists of dextroamphetamine coupled with the essential amino acid L-lysine.
Lisdexamfetamine itself is inactive and acts as a prodrug to dextroamphetamine upon cleavage of the lysine portion of the molecule. It was developed for the intention of creating a longer-lasting and more difficult to abuse version of dextroamphetamine, as the requirement of conversion into dextroamphetamine via enzymes in the red blood cells increases its duration, regardless of the route of ingestion. There is no increased onset or effect as occurs with IV administration of dextroamphetamine compared to oral use of the same. Intravenously administered lisdexamfetamine produced likability effects similar to placebo, therefore affirming the drug's ability to reduce abuse potential.
Lisdexamfetamine is indicated for the treatment of attention deficit hyperactivity disorder (ADHD) in children six to twelve years and in adults as an integral part of a total treatment program that may include other measures (i.e., psychological, educational,
