<P> Lisdexamfetamine ( contracted from L - lysine - dextroamphetamine ) is a prodrug of the central nervous system ( CNS ) stimulant dextroamphetamine , a phenethylamine of the amphetamine class that is used in the treatment of attention deficit hyperactivity disorder ( ADHD ) and binge eating disorder . Its chemical structure consists of dextroamphetamine coupled with the essential amino acid L - lysine . Lisdexamfetamine itself is inactive prior to its absorption and the subsequent rate - limited enzymatic cleavage of the molecule 's L - lysine portion , which produces the active metabolite ( dextroamphetamine ) . </P>
