How does Vyvanse work?
Vyvanse is a central nervous system stimulant. Its active ingredient, lisdexamfetamine, is a prodrug that is converted in the body to dextroamphetamine, which increases the levels of dopamine and norepinephrine in the brain. These neurotransmitters are believed to play a role in attention and impulse control [4].

Adderall is a combination of four different amphetamine salts, including dextroamphetamine and amphetamine. This difference in formulation can affect their onset, duration, and how they are perceived by patients [4][6].
