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.
Dexmethylphenidate is a central nervous system stimulant that blocks the reuptake of norepinephrine and dopamine into presynaptic neurons, increasing their synaptic concentrations. The d-threo enantiomer of methylphenidate is responsible for the therapeutic activity.
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 2.5-5 mg orally twice daily, increase by 2.5-10 mg/day weekly; max 20 mg twice daily.

Terminal half-life in children is approximately 5–6 hours; in adults, approximately 5 hours; wears off within 12 hours of patch removal.
2-3 hours in children and adults; 4-5 hours in adolescents (due to slower metabolism). Clinical context: t1/2 supports twice-daily dosing (immediate-release) for continuous therapeutic effect
Renal (approx. 78% unchanged) and fecal (approx. 10%); remainder as metabolites.
Renal: 80% (approximately 50% as unchanged drug, 30% as metabolites); Fecal: negligible
