What is the adhd daytrana patch?

Daytrana: Is patch made of methylphenidate or ritalin, used if kid can't take pills or did not respond to pill or refused med. By mouth.

Stimulant in patch: Methylphendidate is combined w/ heat sensitive adhesive to release slowly through skin up to 9-14 hours. It's useful if pills can't be swallowed, or if someone needs tighter control of med timing-once swallowed, med can't be retrieved. Once patched, removal ends effect within an hour. Many college students like this control since they can have a stimulant effect for their add for as little 3hrs.
