Vyvanse is a prescription medication commonly used in the treatment of attention deficit hyperactivity disorder (ADHD) and binge eating disorder. It falls under the category of central nervous system stimulants and is classified as a prodrug, meaning it needs to be metabolized in the body to become active. Vyvanse works by increasing the levels of certain neurotransmitters in the brain, particularly dopamine and norepinephrine, which play key roles in regulating attention and impulse control.
