Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
CNS stimulant; increases extracellular dopamine and norepinephrine levels by blocking their reuptake and enhancing release.
Dextroamphetamine is a central nervous system stimulant that increases extracellular dopamine and norepinephrine levels by blocking their reuptake and promoting release from presynaptic terminals.
37.5 mg orally once daily in the morning; may increase by 18.75 mg weekly to a maximum of 112.5 mg/day.
5-10 mg orally once daily in the morning, maximum 20 mg/day.

Terminal elimination half-life is 12-30 hours in children (mean 19 hours) and 8-14 hours in adults; the long half-life supports once-daily dosing, but accumulation can occur with repeated dosing
Terminal elimination half-life 10–13 hours in adults (7–8 hours in children). Longer in alkaline urine (up to 20 hours) due to reduced renal tubular reabsorption.
Primarily renal (80-90% as unchanged drug and metabolites, with 50-60% as unchanged pemoline), minor biliary/fecal elimination (<10%)
Renal: ~90% as unchanged drug and metabolites (primarily deaminated metabolites); fecal/biliary <2%.
