Vyvanse is a prodrug: Its chemical structure consists of dextroamphetamine coupled with the essential amino acid, L-lysine, called Lisdexamfetamine (L-lysine-dextroamphetamine). It must be converted in the body to the active stimulant, dextroamphetamine. It is useful for treatment of ADHD because the time necessary for the body to convert it allows it to be active much longer than dextroamphetamine itself.
