Hi,
I got a pamphlet titled ADHD in Adults, What to Expect With ADDERALL XR. Inside this pamphlet they show us a graphic about Pharmacokinetic studies of ADDERALL XR, they said that the time to reach maximum plasma concentration (Tmax) for ADDERALL XR is about 7 hours, do this mean it take 7 hours to feel the maximum effect of Adderall XR or the adderall last 7 hours? If anyone got this pamphlet and understand it can you please reply to this post and explain this adderall graphic to me? Hopefully soon somone will reply.:)
