Hypnotic drugs are a class of
drugs that induce
sleep (which differentiates them from the
sedative category), used in the treatment of severe
insomnia and in surgical anesthesia. Often the treatment of insomnia will not
begin with drugs at all, however, as many (not all) hypnotic
drugs are habit forming. A physician will usually recommend
alternative sleeping patterns and exercise before
prescribing medication for sleep. This is due to a large
number of factors known to disturb the human sleep pattern.
These drugs include
barbiturates,
benzodiazepines,
zolpidem, zaleplon, zopiclone, eszopiclone, chloral hydrate,
chlormethiazole or the
antihistamines
doxylamine, promethazine, and diphenhydramine.
Alcohol is often tried as a hypnotic drug but it is not
particularly effective.
