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.
CNS stimulant; blocks reuptake of norepinephrine and dopamine into presynaptic neurons, increasing their synaptic concentrations.
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.

Terminal half-life in children is approximately 5–6 hours; in adults, approximately 5 hours; wears off within 12 hours of patch removal.
Terminal elimination half-life for d-amphetamine is 10-13 hours; for l-amphetamine, 13-16 hours. Clinical context: Twice-daily dosing may be required for sustained effect.
Renal (approx. 78% unchanged) and fecal (approx. 10%); remainder as metabolites.
Renal: ~90% as unchanged amphetamine and metabolites. Fecal: minimal (<5%).
