Pharmacology
Indication For the treatment of insomnia.
Pharmacodynamics Glutethimide is a hypnotic sedative that was introduced in 1954 as a safe alternative to barbiturates to treat insomnia. Before long, however, it had become clear that glutethimide was just as likely to cause addiction and caused similarly severe withdrawal symptoms.
Mechanism of action Glutethimide seems to be a GABA agonist which helps induced sedation. It also induces CYP 2D6. When taken with codeine, it enables the body to convert higher amounts of the codeine (higher than the average 5 - 10%) to morphine. The general sedative effect also adds to the power of the combination.

Protein binding Not Available
Metabolism
Hepatic. Glutethimide is almost completely metabolized.
Route of elimination glutethimide is inactivated by conjugation and the metabolites are excreted in urine, only 2% of the parent substance is excreted in urine, up to 2% of the dose has been reported to be found in the faeces.
Half life 10-12 hours
Clearance Not Available
Toxicity In adults, death has been reported after 5 g. The usual lethal dose is 10 to 20g, although survival after a dose of 28 g has been reported.

Drug Interaction
Acenocoumarol Glutethimide may decrease the anticoagulant effect of acenocoumarol.
Anisindione Glutethimide may decrease the anticoagulant effect of anisindione.
Dicumarol Glutethimide may decrease the anticoagulant effect of dicumarol.
Donepezil Possible antagonism of action
Galantamine Possible antagonism of action
Rivastigmine Possible antagonism of action
Triprolidine The CNS depressants, Triprolidine and Glutethimide, may increase adverse/toxic effects due to additivity. Monitor for increased CNS depressant effects during concomitant therapy.
Warfarin Glutethimide may decrease the serum concentration of warfarin by increasing its metabolism. Consider alternate therapy or monitor for changes in the therapeutic and adverse effects of warfarin if glutethimide is initiated, discontinued or dose changed.
Food Interactions
  • Avoid alcohol.
  • Take without regard to meals.
