Adderall & Vyvanse

Adderall (mixed amphetamine salts) and Vyvanse (lisdexamfetamine, a prodrug that converts to dextroamphetamine) are prescription stimulant medications primarily used for attention-deficit/hyperactivity disorder (ADHD) and narcolepsy. Both drugs increase levels of dopamine and norepinephrine in the brain by blocking reuptake transporters and promoting release of these neurotransmitters. Vyvanse is designed to provide longer-lasting effects through its prodrug conversion mechanism, while Adderall's immediate-release and extended-release formulations offer different duration profiles. These medications can significantly affect motivation, focus, arousal, and stress response through their actions on catecholamine systems.
