Adderall is available as immediate-release tablets or two different extended-release formulations.
The extended-release capsules are generally used in the morning. A shorter, 12-hour extended-release formulation is available under the brand Adderall XR and is designed to provide a therapeutic effect and plasma concentrations identical to taking two doses 4 hours apart. The longer extended-release formulation, approved for 16 hours, is available under the brand Mydayis. In the United States, the immediate and extended-release (XR) formulations of Adderall are both available as generic drugs, while Mydayis is available only as a brand-name drug. Buy Adderall Online
