Adderall contains a levoamphetamine element.
Adderall . The two amphetamine enantiomers that compose Adderall ( i.e. , levoamphetamine and dextroamphetamine ) alleviate the symptoms of ADHD and narcolepsy by increasing the activity of the neurotransmitters norepinephrine and dopamine in the brain , which results from their interactions with trace amine associated receptor 1 ( TAAR1 ) and vesicular monoamine transporter 2 ( VMAT2 ) in neurons . The levoamphetamine component of Adderall has been reported to improve the treatment response in some individuals relative to dextroamphetamine alone .
