Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Methylphenidate is a central nervous system stimulant that blocks the reuptake of norepinephrine and dopamine into presynaptic neurons, increasing their extracellular concentrations.
Extended-release oral suspension formulation of methylphenidate, a central nervous system stimulant that inhibits the reuptake of dopamine and norepinephrine into presynaptic neurons, increasing their synaptic concentrations. The exact therapeutic effect in ADHD is unknown but is thought to involve dopaminergic and noradrenergic pathways in the prefrontal cortex.
Initial: 10 mg transdermal patch applied to hip for 9 hours daily; may titrate weekly in increments of 5 mg to a maximum of 30 mg/day.
Initial: 25 mg orally once daily in the morning; may increase weekly in 25 mg increments based on tolerability and response. Maximum: 75 mg once daily.

Terminal half-life in children is approximately 5–6 hours; in adults, approximately 5 hours; wears off within 12 hours of patch removal.
Approximately 4 hours; extended-release formulation provides therapeutic levels for ~12 hours.
Renal (approx. 78% unchanged) and fecal (approx. 10%); remainder as metabolites.
Primarily renal (approximately 60% as unchanged drug); fecal excretion accounts for <5%.
