The stimulant that is most like Vyvanse is Adderall which is also used to treat ADHD.
Both Adderall also known as amphetamine and dextroamphetamine and Vyvanse which is a lisdexamfetamine prodrug belong to the same class of drugs known as central nervous system stimulants.
And both Vyvanse and Adderall share similar mechanisms of action as well as uses.
Adderall and Vyvanse are both stimulant drugs which increase the dopamine and the noprepinephrine levels in your brain, which also helps to improve your attention, reduce hyperactivity, impulsivity and focus.
Both Adderall and Vyvanse are used in the treatment of ADHD in both adults and children.
Adderall is also available in extended release forms and immediate release forms and Vyvanse is only an extended release medication.
Since Vyvanse is a lisdexamfetamine prodrug it means that Vyvanse is converted into dextroamphetamine in the body and can lead to a more gradual as well as sustained release of the active ingredient when compared to the drug Adderall.
Some people who take either Vyvanse or Adderall may experience some different side effects or find that one medication is more effective than the other medication.
Some other stimulant medications for ADHD are Strattera "atomoxetine", Quillivant XR, Concerta and Ritalin also known as methylphenidate.
