Vyvanse (Lisdexamphetamine ) is an oral medication used primarily to treat the symptoms of Attention Deficit Hyperactivity Disorder (ADHD) along with behavioral therapies and counseling. It is designed to be converted to dextroamphetamine in the body, making it a longer lasting drug.

It is part of a class of medications called amphetamine salts and is a central nervous system stimulant. It works by increasing the levels of norepinephrine and dopamine in the brain, two neurotransmitter chemicals that play an important role in maintaining mental acuity.

Vyvanse is the same chemical molecule as Adderall, but the orientation of the molecule is different in the two. Adderall is a mixed formula of the differently oriented molecules, while Vyvanse is all one. This may lead to reduced side effects in some people. However, each person may respond differently to each forumlation

Vyvanse is only approved by the FDA for ADHD, but it is being investigated to help treat several other illnesses, such as depression, schizophrenia, and binge eating disorder.
