Nuvigil is a wakefulness-promoting agent used to treat excessive sleepiness in adults associated with narcolepsy, obstructive sleep apnea, and shift work sleep disorder [1][2]. It is the brand name for armodafinil [1].
What is the difference between Nuvigil and Provigil?
Nuvigil (armodafinil) is a different drug from Provigil (modafinil). While both are used to treat excessive sleepiness, Nuvigil is the R-enantiomer of modafinil, meaning it is the single active enantiomer [1][3]. This distinction can lead to differences in how the drugs are metabolized and their duration of action [3].
How does Nuvigil work?
The exact mechanism of action for Nuvigil is not fully understood [1]. However, it is believed to affect neurotransmitter levels in the brain, such as dopamine, norepinephrine, and serotonin, which are involved in regulating wakefulness and alertness [1][4].
When does Nuvigil's patent expire?
Information on specific patent expiry dates for Nuvigil can be found through patent tracking services. DrugPatentWatch.com is a resource that provides detailed information on drug patents and their expiration dates [5].
