What is the metabolite of diazepam?
What is the metabolite of diazepam?
The main active metabolite of diazepam is desmethyldiazepam (also known as nordazepam or nordiazepam). Its other active metabolites include the minor active metabolites temazepam and oxazepam. These metabolites are conjugated with glucuronide, and are excreted primarily in the urine.
Which reaction will produce oxazepam from diazepam?
Oxazepam is a central-acting CNS depressant with action similar to diazepam. Its mechanism of action appears to be via potentiation of gamma aminobutyric acid (GABA)-receptor–mediated effects in the CNS. Oxazepam is one of the active products of metabolism from diazepam.
What is oxazepam and diazepam?
Controls anxiety symptoms and alcohol withdrawal. Serax (oxazepam) is also good for short-term relief of anxiety symptoms. Valium (diazepam) effectively relieves anxiety and muscle spasms. Valium (diazepam) has less severe withdrawal symptoms compared to other similar drugs. Works very quickly.
Where is oxazepam metabolized?
Oxazepam is primarily eliminated in the urine as its glucuronide metabolite, with the feces containing approximately 21% of the unchanged drug. The majority of an orally ingested dose of oxazepam is excreted within 48 hours. The mean elimination half-life of oxazepam is 8.2 hours.
How long does diazepam peak?
After oral administration >90% of diazepam is absorbed and the average time to achieve peak plasma concentrations is 1 – 1.5 hours with a range of 0.25 to 2.5 hours.
Is oxazepam stronger than diazepam?
Overall, these results extend previous experimental observations suggesting that diazepam has a higher abuse liability than oxazepam. The results are also compatible with an analysis of epidemiological data showing that diazepam abuse uniformly exceeds oxazepam abuse on seven epidemiological measures of drug abuse.
Why is diazepam bad for you?
Using this drug, even as prescribed, can lead to physical dependence and withdrawal if you stop taking the drug suddenly. Withdrawal can be life threatening. Taking this drug can also lead to misuse and addiction. Misuse of diazepam increases your risk for overdose and death.
How long will 2mg diazepam last?
The physiological effects of diazepam only last about 5 hours. However, diazepam is a long acting benzo that stays in your system for several days. The half-life of Valium is 20 hours. This means that it takes about 20 hours for half of the original dose to exit your system.
How is diazepam metabolized in the human body?
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.
Is there any pharmacokinetic interaction between oxazepam and diazepam?
As oxazepam is an active metabolite of diazepam, an overlap in possible interactions is likely with other drugs or food, with exception of the pharmacokinetic CYP450 interactions (e.g. with cimetidine).
How are oxazepam and Nordiazepam metabolized in the body?
It is metabolized to nordiazepam by cytochrome P450 (CYP) 2C19 or to temazepam by CYP 3A4 (1). These metabolites are biotransformed to oxazepam by hydroxylation or demethylation (Figure 1) (2, 3). Nordiazepam, temazepam and oxazepam are pharmacologically active, and the latter two metabolites are commercially available medications.
What are the metabolites of benzodiazepines in urine?
Metabolites Benzodiazepines are extensively metabolized, and the parent compounds are not detected in urine. Diazepam is metabolized to nordiazepam, oxazepam, and temazepam; all may be detected after diazepam use. Diazepam → Nordiazepam, Oxazepam, and Temazepam
