== Adderall vs. Vyvanse ==
Adderall and Vyvanse are both central nervous system stimulants prescribed for the treatment of attention deficit hyperactivity disorder (ADHD).<ref name="ref1" /><ref name="ref2" /><ref name="ref3" /> While both medications contain amphetamines and work by increasing the levels of dopamine and norepinephrine in the brain, there are key differences in their chemical composition, mechanism of action, and approved uses.<ref name="ref4" /><ref name="ref5" /> Adderall contains a combination of four different amphetamine salts, while Vyvanse's active ingredient is lisdexamfetamine.<ref name="ref4" /><ref name="ref1" />

Lisdexamfetamine is a prodrug, meaning it is inactive until it is metabolized in the body.<ref name="ref4" /> This conversion process to dextroamphetamine occurs in the bloodstream.<ref name="ref4" /> This results in a more gradual onset and offset of effects compared to Adderall. Adderall is available in both immediate-release (IR) and extended-release (XR) formulations, while Vyvanse is only available in a long-acting form.<ref name="ref1" /><ref name="ref5" /> The duration of action for Adderall IR is about 4-6 hours, with the XR version lasting up to 12 hours.<ref name="ref1" /><ref name="ref5" /> Vyvanse's effects typically last for 10 to 13 hours.<ref name="ref1" /><ref name="ref5" />

The differing formulations affect how the medications are used and their potential for misuse. Because Vyvanse requires metabolic conversion to become active, it has a lower potential for abuse via non-oral routes such as snorting or injection. Both medications are classified as Schedule II controlled substances due to their potential for dependence and misuse.<ref name="ref1" />

In addition to ADHD, Adderall is also approved for the treatment of narcolepsy.<ref name="ref1" /> Vyvanse is also approved to treat binge eating disorder in adults.<ref name="ref1" /> The side effect profiles of both drugs are similar and can include loss of appetite, insomnia, and increased heart rate.<ref name="ref1" /><ref name="ref2" />
