To date, more than 5 million VYVANSE prescriptions have been filled, bringing the current market share to 12 percent based on weekly branded prescription volume. Additionally, VYVANSE formulary coverage has been positive, with 10 of 11 top managed care plans covering the product in a preferred formulary position.
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.
