Background

Adrafinil is a mild central nervous system stimulating drug typically employed to relieve excessive sleepiness and inattention in geriatric patients. It is also been used off-label to prevent fatigue or falling asleep for extended periods of time. Adrafinil does not currently have FDA approval and is thus unregulated in the United States. It was marketed in France and elsewhere in Europe under the trade name Olmifon until September 2011 when France's FDA equivalent reassessed the drug and withdrew marketing permission. Adrafinil is metabolized to modafinil.

Pharmacodynamics

Adrafinil is a prodrug; it is primarily metabolized in vivo to modafinil, resulting in nearly identical pharmacological effects. Unlike modafinil, the active metabolite must accumulate before the drug is able to act. Oral adrafinil without food usually begins to act within 45 minutes to 1 hour.
