It is manufactured by Shire US, Inc.
How Does It Work?
Adderall XR is a stimulant, although it has effects that are opposite from what would be expected of a stimulant. While stimulants (like caffeine) can cause hyperactivity, Adderall XR can have a calming effect. While the exact way it produces a calming effect is not known, it is known that the medication affects chemicals in the brain.
Adderall XR is a medication that is designed to dissolve slowly. Because the medication is released slowly, it can be taken just once a day, eliminating the need to take medication at school or work.
There have been several studies looking at using Adderall XR for ADHD symptoms. Some of the results of these ADHD research studies are highlighted below.
