A wakefulness-promoting agent (WPA), or wake-promoting agent, is a drug that increases wakefulness and arousal.[1][2][3] They are similar to but distinct from psychostimulants, which not only promote wakefulness but also produce other more overt central nervous system effects, such as improved mood, energy, and motivation.[1][4] Wakefulness-promoting agents are used to treat narcolepsy and hypersomnia as well as to promote wakefulness and increase performance in healthy people.[5][6][7]

A variety of different classes of drugs have shown wakefulness-promoting effects, including:[8][5][3][9]
- Dopamine reuptake inhibitors like modafinil, armodafinil, mesocarb, phenylpiracetam, and vanoxerine[8][5][9][10][11]
- Norepinephrine–dopamine reuptake inhibitors like methylphenidate, solriamfetol, mazindol, bupropion, nomifensine, and amineptine[8][9]
- Norepinephrine–dopamine releasing agents like amphetamine and methamphetamine[8][9]
- Norepinephrine reuptake inhibitors like atomoxetine and reboxetine[8][9]
- Norepinephrine releasing agents like ephedrine and selegiline (via its metabolites)[8][5]
- Dopamine D1 receptor positive allosteric modulators like mevidalen[12][13]
- Adenosine receptor antagonists like caffeine, paraxanthine, and istradefylline[8][5][14][15]
- Histamine H3 receptor antagonists and inverse agonists like pitolisant and samelisant[9]
- Orexin receptor agonists like danavorexton and suntinorexton[5]
- Nicotinic acetylcholine receptor agonists like nicotine[1][16]
Histamine and other histamine H1 receptor agonists also have wakefulness-promoting effects.[9][17][18] However, H1 receptor agonists as drugs are limited by their mediation of allergy-type symptoms.[18]
Certain other drugs are being studied as wakefulness-promoting agents as well, including GABAA receptor antagonists and negative allosteric modulators like clarithromycin, flumazenil, and pentylenetetrazol (pentetrazol), among others.[19]
Aside from the above-described wakefulness-promoting agents, the GHB and GABAB receptor agonist sodium oxybate or γ-hydroxybutyrate (GHB) has been used in the treatment of narcolepsy.[20][8][5][3] Relatedly, some researchers have classified this drug as a stimulant-like agent.[20] However, GHB is taken at night and only results in improved wakefulness the next day following sleep.[20]
The related term "eugeroic" (or "eugregoric") means "vigilance-promoting".[5] It was introduced in 1987 in the French literature and has been used as an alternative term to refer to wakefulness-promoting drugs and to distinguish them from psychostimulants.[5] However, the term has usually been used to refer specifically to modafinil and its analogues, even to the exclusion of other wakefulness-promoting agents.[5][21][22] Moreover, the term has not been widely adopted in the scientific literature.[5] The discovery of wakefulness-promoting neurons and the orexin neuropeptides has prompted a terminological shift away from the concept of "vigilance-promoting" to "wakefulness-promoting".[5]

Phenylpiracetam was originally designed as a nootropic drug for the sustenance and improvement of the physical condition and cognition abilities of Soviet space crews.2 Later, especially during the last decade, phenylpiracetam was introduced into general clinical practice in Russia and in some Eastern European countries. The possible target receptors and mechanisms for the acute activity of this drug remained unclear, until very recently it was found that (R)-phenylpiracetam (5) (MRZ-9547) is a selective dopamine transporter inhibitor that moderately stimulates striatal dopamine release.19
