Chloral hydrate is a geminal diol with the formula Cl 3 C−CH(OH) 2. It was first used as a sedative and hypnotic in Germany in the 1870s. Over time it was replaced by safer and more effective alternatives but it remained in usage in the United States until at least the 1970s. [ 4 ]
Clomethiazole is particularly toxic and dangerous if overdosed and is potentially fatal. Alcohol multiplies the effect. As the drug can be fatal in high doses, prescribing clomethiazole for the management of alcohol dependence outside of a controlled environment, for example a hospital, is not recommended, especially because there are much less toxic alternatives, such as diazepam.
Flunitrazepam has a long half-life of 18–26 hours, which means that flunitrazepam's effects after nighttime administration persist throughout the next day. [16] This is due to the production of active metabolites. These metabolites further increase the duration of drug action compared to benzodiazepines that produce nonactive metabolites. [30]
Flurazepam is a long-acting benzodiazepine and is sometimes used in patients who have difficulty in maintaining sleep, though benzodiazepines with intermediate half-lives such as loprazolam, lormetazepam, and temazepam are also indicated for patients with difficulty maintaining sleep.
Chloral hydrates to chloral hydrate in the body. Chloral hydrate is either reduced to 2,2,2-trichloroethanol or oxidised to trichloroacetic acid . Monochloroacetic acid , [ 38 ] dichloroacetic acid [ 39 ] and trichloromethane [ 38 ] [ 40 ] [ 41 ] were also detected as minor metabolites of TCE.
The half-life of chlordiazepoxide is from 5 to 30 hours but has an active benzodiazepine metabolite, nordiazepam, which has a half-life of 36 to 200 hours. [31] The half-life of chlordiazepoxide increases significantly in the elderly, which may result in prolonged action as well as accumulation of the drug during repeated administration.

Research about using medications to treat insomnia evolved throughout the last half of the 20th century. Treatment for insomnia in psychiatry dates back to 1869, when chloral hydrate was first used as a soporific. [12] Barbiturates emerged as the first class of drugs in the early 1900s, [13] after which chemical substitution allowed derivative ...
