Mechanism of action

Methylphenidate is a sympathomimetic amine that blocks the reuptake of dopamine and norepinephrine at the presynaptic neuron, increasing their concentration in the synaptic cleft. The extended-release formulation provides sustained drug delivery over 12 hours, allowing once-daily dosing. This mechanism enhances executive function, attention span, and impulse control in patients with attention-deficit/hyperactivity disorder.
