Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
CNS stimulant; blocks reuptake of norepinephrine and dopamine into presynaptic neurons, increasing their synaptic concentrations.
Methylphenidate is a central nervous system (CNS) stimulant. It blocks the reuptake of norepinephrine and dopamine into the presynaptic neuron, increasing their levels in the extraneuronal space. The precise mechanism for treating ADHD is not fully understood.

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.
Terminal elimination half-life: 6.8 hours (range 4.5-10.3 hours) for methylphenidate; clinical context: supports twice-daily dosing regimen
Renal: ~90% as unchanged amphetamine and metabolites. Fecal: minimal (<5%).
Renal: 78-97% as metabolites (primarily ritalinic acid), unchanged drug <1%; fecal: <2%
