Adderall contains a levoamphetamine component.
The two amphetamine enantiomers that compose Adderall -LRB- i.e. , levoamphetamine and dextroamphetamine -RRB- 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 -LRB- TAAR1 -RRB- and vesicular monoamine transporter 2 -LRB- VMAT2 -RRB- in neurons.
