N-desmethyl-diazepam and temazepam are both further metabolized to oxazepam. Concomitant intake of inhibitors or inducers of the CYP isozymes involved in the biotransformation of diazepam may alter plasma concentrations of this drug, although this effect is unlikely to be associated with clinically ...
Temazepam and oxazepam are further largely eliminated by way of conjugation to glucuronic acid via glucuronidation 15,16. Furthermore, oxidation of diazepam is mediated by cytochrome P450 isozymes; formation of desmethyl-diazepam mainly by CYP2C19 and CYP3A and 3-hydroxy-diazepam (temazepam) and ...
N-desmethyldiazepam and temazepam are both further metabolized to oxazepam. Temazepam and oxazepam are largely eliminated by glucuronidation. Elimination The initial distribution phase is followed by a prolonged terminal elimination phase (half-life up to 48 hours). The terminal elimination half-life of...
Metabolism:Diazepam is metabolised in the liver by CYP450 enzymes and biotransformed to three mainactive metabolites,desmethyldiazepam(nordiazepam),temazepam, andoxazepam(Fig. 5.10) (Hillestad, Hansen, & Melsom, 1974;Hillestad, Hansen, Melsom, et al., 1974). Initially, the parent compound is de...
(oxazepam) in plasma. At therapeutic doses, desmethyldiazepam is found in plasma at concentrations equivalent to those of diazepam while oxazepam and temazepam are not usually detectable. Themetabolismof diazepam is primarily hepatic and involves demethylation (involving primarily CYP2C19 and CYP3A4) ...
This list is not complete. Other drugs may affect diazepam, including prescription and over-the-counter medicines, vitamins, andherbal products. Not all possibledrug interactionsare listed here. Further information Remember, keep this and all other medicines out of the reach of children, never share...
Temazepam and oxazepam are largely eliminated by glucuronidation. Elimination The initial distribution phase is followed by a prolonged terminal elimination phase (half-life up to 48 hours). The terminal elimination half-life of the active metabolite N-desmethyldiazepam is up to 100 hours. Diazepam ...
flurazepam and temazepam were found to be the most toxic in overdosage. a later study of another 303 cases of benzodiazepine poisoning3 supported these differences in toxicity as well as pointing to the relative safety of the benzodiazepines in overdosage. see also under alprazolam, p. 1036.1....
Diazepam is a prescription oral medication that is used to treatanxiety.Diazepam also is used for the treatment of agitation, tremors, delirium,seizures, and hallucinations resulting fromalcoholwithdrawal. It is used for the treatment of seizures, relief ofmuscle spasmsin some neurological diseases, ...
Diazepam is N-demethylated by CYP3A4 and 2C19 to the active metabolite N-desmethyldiazepam, and is hydroxylated by CYP3A4 to the active metabolite temazepam. N-desmethyldiazepam and temazepam are both further metabolized to oxazepam. Temazepam and oxazepam are largely eliminated by glucuronidation....
