Wakefulness-promoting agent

A wakefulness-promoting agent is a type of psychoactive drug which improves wakefulness and alertness, and reduces tiredness, drowsiness, and the need for sleep. They are often used in the treatment of hypersomnia and narcolepsy. The functional opposites of wakefulness-promoting agents would be hypnotics/sedatives like antihistamines, opioids, and benzodiazepines.

The prototype drug in this class is modafinil, and other drugs include adrafinil and armodafinil. The primary difference between these drugs and amphetamine-like stimulants is that wakefulness-promoting agents trigger activation of neurons in the hypothalamus-based wakefulness circuits, as opposed to producing diffuse neuronal activation.[1]
