Adrafinil should not be taken in the afternoon and evening, since supplementation would impair sleep.
Adrafinil peaks in the blood of elderly humans approximately one hour after oral ingestion, although neurological effects occur mostly after this peak due to the time it takes to convert it to modafinil, its active metabolite. Adrafinil has a half-life of around five hours based on rat data.
Adrafinil is a stimulant, which is why it promotes wakefulness. It also provides nootropic effects, increasing learning abilities, improving memory, and improving overall brain energy. It is used for a variety of people and situations. Among the most common users are narcolepsy patients, students, and shift workers.
