A nonbarbiturate hypnotic drug whose action on the central nervous system resembles that of alcohol.
Sedative and sleep-inducing drug now seldom used in medicine because of its irritating (to skin and mucous membranes, especially the stomach) and potentially addictive properties. (Combined with alcohol, it is known colloquially as knockout drops or a Mickey Finn.)
A sedative and hypnotic drug used, mainly in children and the elderly, to induce sleep or as a daytime sedative. It is rapidly absorbed from the alimentary canal and is usually given by mouth as a syrup, although it can be administered rectally. Toxic effects are usually only seen with over-dosage. Prolonged use may lead to dependence.
This drug is now rarely used but chloral betaine (Welldorm) is occasionally used in the elderly and in newborns with fits or cerebral irritation after a difficult delivery.
