History
Vyvanse was developed by New River Pharmaceuticals, who were bought by Shire Pharmaceuticals shortly before lisdexamfetamine began being marketed. Vyvanse is approved by the U.S. Food and Drug Administration (FDA) for the treatment of attention-deficit hyperactivity disorder.
On April 23, 2008, Vyvanse received FDA approval for the adult population. In a randomized, double-blind, four-week phase III trial in adult patients with ADHD, 30, 50 or 70mg/day of oral lisdexamfetamine caused a significantly greater improvement in ADHD-Rating Scale total score than placebo.
On February 19, 2009, Health Canada approved 30 mg and 50 mg capsules of lisdexamfetamine for treatment of ADHD.
On February 8, 2012, Vyvanse received FDA approval for maintenance treatment of adult ADHD.
