DEXTROSTAT vs PEMOLINE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dextroamphetamine is a central nervous system stimulant that promotes release of dopamine and norepinephrine from presynaptic neurons, and inhibits their reuptake, thereby increasing synaptic concentrations of these neurotransmitters.
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 per day in divided doses, typically 5-10 mg 2-3 times daily, maximum 60 mg/day.
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).

Terminal elimination half-life is approximately 10-13 hours in adults, 6-8 hours in children. Extended duration allows once-daily dosing in some patients.
Terminal elimination half-life is 8-12 hours in children; 12-16 hours in adults. Steady-state is reached within 2-3 days.
Primarily renal (approximately 90% as unchanged drug and metabolites); minor biliary/fecal elimination (<10%).
Pemoline is primarily excreted renally as unchanged drug (40-50%) and metabolites; approximately 20-30% is excreted in feces via biliary elimination.
