ADDERALL 15 vs ARMODAFINIL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Adderall 15 is a combination of amphetamine and dextroamphetamine, which increase synaptic concentrations of norepinephrine and dopamine 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.
10-20 mg orally once daily in the morning; may increase by 5-10 mg weekly; maximum 40 mg/day.
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.

"The serum concentration of Cyclosporine can be decreased when it is combined with Armodafinil."
Clinical Note
moderateArmodafinil + Aripiprazole

Clinical Note
moderateCyclophosphamide + Armodafinil
Mean terminal half-life: d-amphetamine 10 h, l-amphetamine 13 h (range 9-14 h); for ADDERALL 15 (3:1 mix), effective half-life ~11 h; clinical context: dosing interval typically QD-BID.
12–15 hours (terminal) in adults; longer in hepatic impairment (e.g., 20–30% increase with cirrhosis).
Primarily renal (90% as unchanged drug and metabolites; ~30% unchanged, 40% as 4-hydroxyamphetamine and conjugates, 20% as other metabolites); minimal biliary/fecal elimination (<3%).
Renal: ~80% as metabolites (major: armodafinil acid, minor: modafinil sulfone); fecal: <1% unchanged; biliary: negligible.
