what kind of drug is vyvanse classified as?
prodrug
dextroamphetamine is the active metabolite of the prodrug lisdexamfetamine (l-lysine-dextroamphetamine), available by the brand name vyvanse (elvanse in the european market) (lisdexamfetamine dimesylate). dextroamphetamine is liberated from lisdexamfetamine enzymatically following contact with red blood cells. the conversion is rate-limited by the enzyme, which prevents high blood concentrations of dextroamphetamine and reduces lisdexamfetamine's drug liking and abuse potential at clinical doses. vyvanse is marketed as once-a-day dosing as it provides a slow release of dextroamphetamine into the body. vyvanse is available as capsules, and chewable tablets, and in seven strengths; 10 mg, 20 mg, 30 mg, 40 mg, 50 mg, 60 mg, and 70 mg. the conversion rate between lisdexamfetamine dimesylate (vyvanse) to dextroamphetamine base is 29.5%.
