Ingredients amphetamine and dextroamphetamine directly increase levels of dopamine and norepinephrine in the brain. When the drugs are metabolized, they become inactive and are eliminated. With a prodrug like Vyvanse, the ingredient lisdexamfetamine is inactive. It is only when it is metabolized by the liver that the active drug (dextroamphetamine) is released into the bloodstream. Once dopamine and norepinephrine levels are increased, dextroamphetamine is inactivated and eliminated. The benefit of a prodrug like Vyvanse is that it takes less medication to achieve the same effect as an active drug like Adderall. Because of this, prodrugs are less likely to cause toxicity or side effects. Moreover, a higher proportion of the active drug enters the bloodstream with a prodrug like Vyvanse than an active drug like Adderall. This is because only a portion of Adderall you take by mouth is absorbed into the bloodstream.
