ARMODAFINIL vs PEMOLINE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Armodafinil is a wakefulness-promoting agent. Its mechanism is unclear but may involve inhibition of dopamine reuptake, leading to increased extracellular dopamine levels. It also affects orexin, histamine, norepinephrine, and GABA pathways.
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.
Adults: 150-250 mg orally once daily in the morning for narcolepsy or obstructive sleep apnea; 200-400 mg orally once daily for shift work disorder.
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).

Clinical Note
moderateArmodafinil + Estrone sulfate
"The serum concentration of Estrone sulfate can be decreased when it is combined with Armodafinil."
Clinical Note
moderateArmodafinil + Cyclosporine
"The serum concentration of Cyclosporine can be decreased when it is combined with Armodafinil."
Clinical Note
moderateArmodafinil + Aripiprazole
"The serum concentration of Aripiprazole can be decreased when it is combined with Armodafinil."
Clinical Note
moderateCyclophosphamide + Armodafinil
12–15 hours (terminal) in adults; longer in hepatic impairment (e.g., 20–30% increase with cirrhosis).
Terminal elimination half-life is 8-12 hours in children; 12-16 hours in adults. Steady-state is reached within 2-3 days.
Renal: ~80% as metabolites (major: armodafinil acid, minor: modafinil sulfone); fecal: <1% unchanged; biliary: negligible.
Pemoline is primarily excreted renally as unchanged drug (40-50%) and metabolites; approximately 20-30% is excreted in feces via biliary elimination.
