Methylphenidate blocks the reuptake of dopamine and norepinephrine at the presynaptic neuron, increasing their concentration in the synaptic cleft. The OROS (osmotic release oral system) formulation provides extended-release delivery over 12 hours, maintaining therapeutic levels throughout the day. This mechanism enhances focus, attention, and impulse control in patients with attention deficit hyperactivity disorder.
