Can you tell me specifically how the drug Vyvanse (lisdexamfetamine) works?

Vyvanse (lisdexamfetamine) Two part answer: (1) vyvanse (lisdexamfetamine) is a compounded molecule of a normal Amino Acid and amphetamine. This property allows for its longer action in a unique way to the CNS stimulants as it takes time for the body to break it down before it works. (2) as an stimulant, it increases Dopamine and norepinephrine available to the part of the brain that allows one to inhibit undesired impulses and distractions.
