ADDERALL 12.5 vs PEMOLINE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Adderall 12.5 is a combination of dextroamphetamine and amphetamine. It increases the levels of dopamine and norepinephrine in the central nervous system by inhibiting their reuptake and promoting their release from presynaptic neurons.
Pemoline is a central nervous system stimulant that enhances dopaminergic and noradrenergic transmission by blocking the reuptake of dopamine and norepinephrine at the synaptic cleft. It also has mild monoamine oxidase inhibitory activity.
5-60 mg orally once or twice daily; immediate-release: initial 5 mg once or twice daily, increase by 5 mg weekly; extended-release: initial 20 mg once daily in the morning, increase by 10 mg weekly.
Oral, 37.5 mg once daily in the morning; may increase by 18.75 mg weekly to a maximum of 112.5 mg/day (divided into 2 doses if total dose > 75 mg).

The terminal elimination half-life of d-amphetamine is approximately 10–13 hours in adults (range 9–14 h) and 6–8 hours in children. Clinical context: Typically allows twice-daily dosing; extended-release formulations provide 8–12 hours of effect.
Terminal elimination half-life is 8-12 hours in children; 12-16 hours in adults. Steady-state is reached within 2-3 days.
Approximately 30% of the dose is excreted unchanged in urine; the remainder is metabolized primarily via deamination and oxidation. Renal elimination of unchanged amphetamine is pH-dependent: acidic urine increases elimination, alkaline urine decreases it. Fecal excretion accounts for <5%.
Pemoline is primarily excreted renally as unchanged drug (40-50%) and metabolites; approximately 20-30% is excreted in feces via biliary elimination.
