Toxizität	Glutethimide, and a structurally similar compound methyprylon, has been used occasionally as a sedative-hypnotic, although glutethimide’s use for longer than 3 days is not recommended and it is rarely, if ever, prescribed today. Glutethimide causes a skin rash in nearly 10% of those using it, and although it was once thought to produce less respiratory depression than the barbiturates its overdose fatality record is not good. Much of the drug’s action can be attributed to 4-hydroxyglutethimide, which is more than twice as potent and has a long half-life. Like many other sedativehypnotics, abrupt withdrawal after chronic use or abuse resembles that of ethanol or the barbiturates and must be managed accordingly.

Definition
ChEBI: Glutethimide is a member of piperidines.
Manufacturing Process
The 2-phenyl-2-ethyl-pentane-1,5-diacid-mononitrile-(1) of melting point 72° to 76°C, used as starting material in this process, can be produced for example from α-phenyl-butyric acid nitrile by condensation with acrylic acid methyl ester and subsequent hydrolysis of the thus-obtained 2-phenyl-2- ethyl-pentane-1,5-diacid-monomethyl ester-mononitrile-(1) of boiling point 176° to 185°C under 12 mm pressure.
140 parts by weight of 2-phenyl-2-ethyl-pentane-1,5-diacid-mononitrile-(1) are dissolved in 200 parts by volume of glacial acetic acid and, at an initial temperature of 60°C, 100 parts by volume of concentrated sulfuric acid added in portions. In this operation the temperature of the reaction mixture rises to 100°C. The whole is finally maintained for a short time on the boiling water bath, then cooled and poured on ice and neutralized with alkali to a pH of 6. Extraction with chloroform is then effected and the chloroform extract washed with dilute caustic soda solution, dried over calcium chloride, the chloroform evaporated and the residue crystallized from ethyl acetate with addition of ligroin. The obtained 3-phenyl-3-ethyl-2,6-dioxo-piperidine melts at 78° to 81°C.

Therapeutic Function
Sedative, Hypnotic
Weltgesundheitsorganisation (WHO)
Glutethimide, a piperidine derivative, was introduced in 1955 for use as a sedative-hypnotic drug. Its addiction liability and severity of withdrawal symptoms are equal to those of the barbiturates and it is controlled under Schedule III of the 1971 Convention on Psychotropic Substances. (Reference: (UNCPS3) United Nations Convention on Psychotropic Substances (III), , , 1971)
Allgemeine Beschreibung
Glutethimide, 2-ethyl-2-phenylglutarimide(Doriden), is one of the most active nonbarbituratehypnotics that is structurally similar to the barbiturates,especially phenobarbital. Because of glutethimide’s lowaqueous solubility, its dissolution and absorption from theGI track is somewhat erratic. Consistent with its highlipophilicity, it undergoes extensive oxidative metabolismin the liver with a half-life of approximately 10 hours.Glutethimide is used as a racemic mixture with the (+)enantiomer being primarily metabolized on the glutarimidering and the (—) enantiomer on the phenyl ring. The productof metabolic detoxification is excreted after conjugationwith glucuronic acid at the hydroxyl group. The drug is anenzyme inducer. In the therapeutic dosage range, adverse effectstend to be infrequent. Toxic effects in overdose are assevere as, and possibly more troublesome than, those of thebarbiturates.
Hazard
Manufacture and use controlled by law.
Sicherheitsprofil
Poison by ingestion and intraperitoneal routes. Human systemic effects by ingestion: pupillary dilation, ataxia, somnolence, coma, and blood pressure depression. An experimental teratogen. Other experimental reproductive effects. When heated to decomposition it emits toxic fumes of NOx. Caution: May be habit forming. This is a controlled substance (depressant) listed in the US.
