Vyvanse (Lisdexamfetamine) – Long-Acting ADHD Stimulant (Rx, Controlled Substance)

Vyvanse (lisdexamfetamine) is a central nervous system stimulant used for the treatment of attention deficit hyperactivity disorder (ADHD) in children and adults, and binge eating disorder in adults.

It is a prodrug, meaning it is inactive until metabolized in the body into dextroamphetamine, which increases levels of dopamine and norepinephrine in the brain. This improves focus, attention, impulse control, and wakefulness.

Because it is converted gradually, Vyvanse provides a longer and smoother duration of action compared to some other stimulants.
