Armodafinil (trade name Nuvigil) is the enantiopure compound of the eugeroic modafinil (Provigil).Because armodafinil has a longer half-life than modafinil does, it may be more effective at improving wakefulness in patients with excessive daytime sleepiness.
Many of the benefits of armodafinil are directly from the textbook on modafinil. Yet, there are studies of their own, which focus specifically on the R-modafinil compound.
This function is similar to that of modafinil. Many of the armodafinil benefits are similar because of the structural similarity of these drugs. For example, studies suggest that usage of modafinil could help improve working memory and cognitive abilities in those suffering from methamphetamine withdrawals. It also showed equitable potency with amphetamines for military personnel working multiple night shifts .
These anti-fatigue agents are primarily studied through modafinil, but have overlap with armodafinil as well. The benefits of armodafinil are slightly different, but anecdotal confirmation suggests many of these focus and anti-fatigue benefits are the same.
Beyond that, armodafinil has unique research that other drugs in the family do not. One study showed that patients using armodafinil showed less negative symptoms of schizophrenia.
Finally, one major benefit of armodafinil is that you require far less of the drug to make cognitive changes. The drug only requires around 150 - 200 mg because the R-modafinil active ingredient is so much more potent than modafinil in some ways. It also reaches peak blood concentration later on than modafinil, which means it can last longer.
The difference in armodafinil dosage versus modafinil is not huge, but it is significant. The recommended dosage (for medical patients suffering certain diseases) is 150 mg one time in the morning. This is compared to the 200 mg that users take for modafinil.
