How does armodafinil compare to Modafinil?
Armodafinil is the R-enantiomer of modafinil, meaning it is a specific stereoisomer of the drug. It is generally considered to have a longer duration of action and potentially a more consistent effect profile compared to racemic modafinil, which is a mixture of both R- and S-enantiomers [1].

How does armodafinil affect sleep architecture?
Armodafinil promotes wakefulness and is not designed to replace sleep. While it combats excessive daytime sleepiness, its direct impact on the architecture of sleep itself is a subject of ongoing research, but it is primarily understood as a wakefulness-promoting agent rather than a sleep inducer or regulator [1].
