Mechanism of action

Methylphenidate blocks the reuptake transporters for dopamine and norepinephrine, increasing their synaptic concentrations and enhancing neurotransmission in the prefrontal cortex and striatum. The OROS (osmotic release oral system) delivery mechanism provides controlled, extended release of the drug over approximately 12 hours, maintaining therapeutic levels throughout the day. This sustained-release formulation improves compliance and provides more consistent symptom control compared to immediate-release formulations.
