ARMODAFINIL vs CYLERT
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.
CNS stimulant; increases extracellular dopamine and norepinephrine levels by blocking their reuptake and enhancing release.
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.
37.5 mg orally once daily in the morning; may increase by 18.75 mg weekly to a maximum of 112.5 mg/day.

12–15 hours (terminal) in adults; longer in hepatic impairment (e.g., 20–30% increase with cirrhosis).
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
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
Renal: ~80% as metabolites (major: armodafinil acid, minor: modafinil sulfone); fecal: <1% unchanged; biliary: negligible.
Primarily renal (80-90% as unchanged drug and metabolites, with 50-60% as unchanged pemoline), minor biliary/fecal elimination (<10%)
