ADDERALL XR 10 vs PEMOLINE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Adderall XR 10 contains a mixture of amphetamine salts, which are central nervous system stimulants. The dextroamphetamine and levoamphetamine components increase synaptic concentrations of dopamine and norepinephrine by inhibiting their reuptake and promoting their release from presynaptic terminals. This action leads to enhanced neurotransmission in the prefrontal cortex and other brain regions involved in attention and executive function.
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.
10 mg orally once daily in the morning; maximum dose 40 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).

Dexamphetamine: 10-13 hours in adults (children: 6-8 hours); levoamphetamine: 13-16 hours; clinically, steady-state achieved in approximately 3 days, with twice-daily dosing maintaining therapeutic levels
Terminal elimination half-life is 8-12 hours in children; 12-16 hours in adults. Steady-state is reached within 2-3 days.
Renal (approximately 30-40% as unchanged amphetamine, remainder as metabolites, including deaminated and oxidized products; urinary pH-dependent elimination: acidic pH increases renal clearance, alkaline pH decreases renal clearance; negligible biliary/fecal elimination)
Pemoline is primarily excreted renally as unchanged drug (40-50%) and metabolites; approximately 20-30% is excreted in feces via biliary elimination.
