ADZENYS XR-ODT vs ARMODAFINIL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Adzenys XR-ODT contains amphetamine, a central nervous system stimulant that increases extracellular levels of dopamine and norepinephrine by inhibiting their reuptake and promoting their release from presynaptic terminals.
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.
Initial: 9.4 mg orally once daily in the morning; titrate in increments of 9.4 mg per week based on tolerability and response. Maximum: 56.4 mg once daily.
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.

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
Approximately 9-14 hours in adults, 8-11 hours in children (6-12 years). Extended-release pharmacokinetics produce a longer clinical duration compared to immediate-release formulations.
12–15 hours (terminal) in adults; longer in hepatic impairment (e.g., 20–30% increase with cirrhosis).
Renal: approximately 90% as unchanged drug and metabolites (30%-40% as amphetamine, 40%-50% as hippuric acid and benzoic acid). Fecal: <4%. Biliary: negligible.
Renal: ~80% as metabolites (major: armodafinil acid, minor: modafinil sulfone); fecal: <1% unchanged; biliary: negligible.
