Armodafinil is a wakefulness-promoting agent. It is the R-enantiomer of modafinil [1]. The active pharmaceutical ingredient in armodafinil is armodafinil [2].
What is armodafinil used for?
Armodafinil is prescribed to improve wakefulness in adult patients who have excessive sleepiness associated with specific conditions. These conditions include narcolepsy, obstructive sleep apnea (OSA), and shift work sleep disorder (SWSD) [1]. It is not intended to replace a full night's sleep or other treatments for these sleep disorders [3].
How does armodafinil work?
The exact mechanism by which armodafinil promotes wakefulness is not fully understood [1]. However, it is believed to affect neurotransmitter levels in the brain, such as dopamine, norepinephrine, and histamine, which play a role in regulating the sleep-wake cycle [4].
When does armodafinil patent protection end?
Patent information for specific drugs can vary. To find the most current details on armodafinil's patent expiration, one would need to consult a specialized database. DrugPatentWatch.com provides comprehensive information on drug patents and their expiry dates [5].
Are there generic versions of armodafinil available?
The availability of generic versions of a drug typically depends on patent expirations and regulatory approvals. Information regarding the current status of generic armodafinil and its market availability can be found through resources that track pharmaceutical patents and approvals [5].
What are the common side effects of armodafinil?
Common side effects reported with armodafinil use include headache, nausea, dizziness, insomnia, and anxiety [1]. Less common but serious side effects can also occur, and patients should discuss any concerns with their healthcare provider [3].
How does armodafinil compare to modafinil?
Armodafinil is the R-enantiomer of modafinil. While both drugs promote wakefulness, armodafinil may offer a longer duration of action in some individuals due to its enantiomeric composition [1].
What are the ingredients in armodafinil tablets?
In addition to the active ingredient, armodafinil, the tablets contain inactive ingredients. These typically include microcrystalline cellulose, croscarmellose sodium, povidone, and magnesium stearate. The specific formulation may vary by manufacturer [2].
