Question: Is armodafinil used for treatment of insomnia?

Context:
 Other therapies, such as sedative hypnotics, target daytime insomnia, while pharmacologic agents such as modafinil, armodafinil, and caffeine and non-pharmacologic approaches such as napping promote nighttime alertness.
Other treatment options may include pharmacologic interventions such as modafinil and armodafinil, which have shown efficacy in this population.
BACKGROUND: Armodafinil (Nuvigil(®), Cephalon, Inc., Frazer, PA, USA), the longer-lasting isomer of racemic modafinil, is a nonamphetamine, wakefulness-promoting medication. In patients with excessive sleepiness associated with shift work disorder, treated obstructive sleep apnoea, or narcolepsy, armodafinil has been found to improve wakefulness throughout the shift or day. In addition, while not approved for this indication, armodafinil has been found to improve excessive sleepiness associated with jet-lag disorder.
STUDY OBJECTIVES: Armodafinil is a wakefulness-promoting medication. Its efficacy and tolerability have been established in 12-week studies of patients with excessive sleepiness (ES) associated with treated obstructive sleep apnea (OSA), shift work disorder (SWD), or narcolepsy. 
Armodafinil represents an option for long-term treatment of patients with ES associated with treated OSA, SWD, or narcolepsy.
The wakefulness-promoting agents armodafinil and modafinil are FDA approved for the treatment of ES in patients with SWD.
CONCLUSIONS: Armodafinil significantly improved overall clinical condition related to excessive sleepiness as rated by the CGI-C and was well tolerated in patients with treated OSA and comorbid depression.
CONCLUSION: In patients with excessive sleepiness associated with chronic SWD of moderate or greater severity, armodafinil significantly improved wakefulness during scheduled night work, raising mean nighttime sleep latency above the level considered to indicate severe sleepiness during the daytime. Armodafinil also significantly improved measures of overall clinical condition, long-term memory, and attention. 
Adjunct treatment with armodafinil significantly improved wakefulness, long-term memory, and patients' ability to engage in activities of daily living in nCPAP-adherent individuals with ES associated with OSA. 
A number of studies have evaluated countermeasures or interventions in shift workers; proposed treatments include chronobiotic interventions, such as light exposure, melatonin, hypnotic agents, caffeine and CNS stimulants (amphetamine), and the wake-promoting agents modafinil and armodafinil. 
These studies showed that modafinil and armodafinil significantly improve the ability to sustain wakefulness during waking activities (e.g. working, driving), overall clinical condition, and sustained attention or memory in patients with SWSD. 
CONCLUSIONS: In this selected population of patients with OSA/HS and residual ES despite effective treatment with nCPAP, armodafinil QD used as an adjunct to nCPAP treatment was associated with improved wakefulness and overall clinical condition.

Answer: No, armodafinil is not used for treatment of insomnia. Armodafinil is a wakefulness-promoting medication. Its efficacy and tolerability have been established in patients with excessive sleepiness (ES) associated with treated obstructive sleep apnea (OSA), shift work disorder (SWD), or narcolepsy. The wakefulness-promoting agents armodafinil and modafinil are FDA approved for the treatment of ES in patients with SWD.
