1. A sleep-inducing drug.
2. A person with narcolepsy


(năr′kō-lĕp″sē) [Gr. narke, numbness, + lepsis, seizure]
A disorder marked by recurrent, uncontrollable attacks of daytime sleepiness, often associated with temporary muscular paralysis (cataplexy), which may occur after powerful emotional experiences. People affected by this condition may have several sleep attacks each day. Typically, narcoleptic patients arouse from sleep relatively easily. narcoleptic (năr-kō-lĕp′tĭk), adjective


Narcolepsy occurs in families, and about 90% of affected people have specific human leukocyte antigens (HLA-DQw6 or HLA-DR2). People with narcolepsy have diminished levels of peptides in the brain, called orexins, that influence sleep and consciousness.


Scheduled naps during the day may prevent sleep attacks, especially if the naps are timed to occur when the patient usually experiences sleep attacks. Drugs used to treat narcolepsy include stimulants such as dextroamphetamine sulfate, pemoline, or methylphenidate hydrochloride.


Narcoleptics should avoid activities that require constant alertness (e.g., driving or flying). At the first sign of drowsiness, affected patients should seek a safe place to sleep. In many states in the U.S., loss of consciousness is grounds for revocation of driving privileges. Patients with narcolepsy should review their motor vehicle usage with their health care professionals.

A. Narcolepsy cannot yet be cured. But EDS and cataplexy, the most disabling symptoms of the disorder, can be controlled in most patients with drug treatment. Often the treatment regimen is modified as symptoms change. For decades, doctors have used central nervous system stimulants-amphetamines such as methylphenidate, dextroamphetamine, methamphetamine, and pemoline-to alleviate EDS and reduce the incidence of sleep attacks. For most patients these medications are generally quite effective at reducing daytime drowsiness and improving levels of alertness. However, they are associated with a wide array of undesirable side effects so their use must be carefully monitored. Common side effects include irritability and nervousness, shakiness, disturbances in heart rhythm, stomach upset, nighttime sleep disruption, and anorexia. For full article: Hope this helps.
