Concerta
® (
methylphenidate extended release) is a prescription medication used for the treatment of attention deficit hyperactivity disorder (
ADHD) in children, teens, and adults up to age 65. It is designed to be released slowly over time. Because the medication is released slowly, it can be taken just once a day, eliminating the need to take medication at school or work.
Concerta is manufactured by ALZA Corporation, and is distributed and marketed by McNeil Pediatrics.
Concerta 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, this medication has a calming effect. While the exact way the drug produces this effect is not known, it is known to affect certain chemicals in the brain
(see Methylphenidate and D2 Receptors).
Concerta is a tablet that is released in two stages: The outer part of the tablet dissolves quickly and releases an immediate dose. The inner part releases the rest of the medication slowly over time.
