Lisdexamfetamine (contracted from L-lysine-dextroamphetamine) is a central nervous system (CNS) stimulant prodrug of thephenethylamine and amphetamine chemical classes. Its chemical structure consists of dextroamphetamine coupled with the essential amino acid L-lysine. Lisdexamfetamine itself is inactive and acts as a prodrug to dextroamphetamine upon cleavage of the lysine portion of the molecule.
The U.S. Food and Drug Administration today expanded the approved uses of Vyvanse (lisdexamfetamine dimesylate) to treat binge-eating disorder in adults. The drug is the first FDA-approved medication to treat this condition.
In binge-eating disorder, patients have recurrent episodes of compulsive overeating during which they consume larger amounts of food than normal and experience the sense that they lack control. Patients with this condition eat when they are not hungry and often eat to the point of being uncomfortably full. Patients may feel ashamed and embarrassed by how much they are eating, which can result in social isolation. Binge-eating disorder may lead to weight gain and to health problems related to obesity.
