Concerta (Methylphenidate Hydrochloride) – Extended-Release ADHD Medication (Rx)

Concerta (methylphenidate hydrochloride) is a central nervous system (CNS) stimulant indicated for the treatment of attention deficit hyperactivity disorder (ADHD) in children (≥6 years), adolescents, and adults (depending on regional approval). It is designed for once-daily administration, providing extended symptom control throughout the day.

Concerta uses OROS (osmotic-controlled release oral delivery system) technology, delivering methylphenidate in a controlled manner to maintain stable plasma concentrations. It works by inhibiting the reuptake of dopamine and norepinephrine, enhancing neurotransmission in brain regions responsible for attention, focus, and executive function.
