Question: how does vyvanse break down in the body?
Answer: Vyvanse is a pro-drug of dextroamphetamine. After oral administration, lisdexamfetamine dimesylate is rapidly absorbed from the gastrointestinal tract and converted to dextroamphetamine, which is responsible for the drug's activity. Amphetamines are non- catecholamine sympathomimetic amines with CNS stimulant activity.
