VYVANSE, which was introduced in the United States in July 2007 for the treatment of ADHD in children age 6 to 12 years and approved in April 2008 to treat ADHD in adults, is currently available in six dosage strengths of 20 mg, 30 mg, 40 mg, 50 mg, 60 mg, and 70 mg. To date, more than 6 million VYVANSE prescriptions have been filled, bringing the current US market share to over 12 percent based on weekly branded prescription volume. Additionally, Shire has executed agreements with 10 of Shire's top 11 managed care organizations (MCOs) to cover VYVANSE in a preferred formulary position. Approximately 95 percent of prescriptions are approved by health plans at the national average copay of $34.00. These figures are comparable with other ADHD treatment options.
VYVANSE is a therapeutically inactive prodrug, in which d-amphetamine is covalently bonded to l-lysine, and after oral ingestion it is converted to pharmacologically active d-amphetamine. The conversion of VYVANSE to d-amphetamine is not affected by gastrointestinal pH and is unlikely to be affected by alterations in GI transit times.
Additional information about VYVANSE and Full Prescribing Information, including the Medication Guide, are available at www.vyvanse.com.
