Which of the following medications is prescribed for ADHD?

Concerta is a medication specifically indicated for the treatment of Attention Deficit Hyperactivity Disorder (ADHD). It contains methylphenidate, which is a stimulant that affects chemicals in the brain and nerves that contribute to hyperactivity and impulse control. Concerta is designed to help improve focus, attention, and self-control in patients diagnosed with ADHD, making it a commonly prescribed option for this condition.

In contrast, other medications listed do not serve this purpose. For instance, Ambien is used primarily to treat insomnia, Motrin is an anti-inflammatory medication often used for pain relief or reducing fever, and Robaxin is a muscle relaxant. Each of these serves a different therapeutic area and does not have the same indications for the treatment of ADHD as Concerta does.
