Adrafinil

Adrafinil (INN) (brand name Olmifon) is a discontinued wakefulness-promoting agent (or eugeroic) that was formerly used in France to promote vigilance (alertness), attention, wakefulness, mood, and other parameters, particularly in the elderly. It was also used off-label by individuals who wished to avoid fatigue, such as night workers or others who needed to stay awake and alert for long periods of time. Additionally, "adrafinil is known to a larger nonscientific audience, where it is considered to be a nootropic agent."
