| Toxicity | 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. |
DL-Glutethimide Chemical Properties,Uses,Production
Chemical Properties
White, crystalline powder.Saturated solution is slightly acid. Freely soluble in acetone, ethyl acetate, and chloroform; soluble in ethanol and methanol; practically insoluble in water.
Uses
Sedative-hypnotic.
World Health Organization (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)
General Description
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.
Safety Profile
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. Code of Federal Regulations, Title 21 Part 1308.13 (1985)
Purification Methods
Crystallise glutethimide from diethyl ether or ethyl acetate/pet ether. It has m 91-92o (from aqueous EtOH), 87-87.5o (from Et2O/pet ether), 84-87o (from isopropanol), and 83-84o (from Et2O).
