Abstract. 1. The primary metabolism of diazepam was studied in human liver microsomes in order to investigate the kinetics and to identify the cytochrome P (CYP) isoforms responsible for the formation of the main diazepam metabolites, temazepam and by: METABOLISM IN VITRO OF 3H-DIAZEPAM BY g SUPERNATANTS* OF RAT LIVER Rat treatment Substrate and extractable metabolites after 1 hr incubationf Diazepam I II Oxazepam Unaccounted (pmole) (jiimole) (pmole) (pinole) for (gniole) Control nil Phénobarbital * See table 3, first footnote. + The Cited by: 7.

Benzodiazepines are one of the most commonly prescribed medications to treat anxiety, insomnia, and other conditions in the United States. 1,2 In , approximately % of US adults ( years old) have used benzodiazepines, and the percentage increases with age.1 Benzodiazepine core chemical structure is composed of diazepine fused to a benzene Size: KB.

Pooled human liver microsomes (HLMs) are a suitable source of enzymes for examining in vitro human metabolism as they contain the major drugmetabolizing enzymes: the cytochrome P s (CYPs) and.   Drug metabolism studies are essential and necessary during the evaluation of drugs. This review discusses the in vitro human liver models to estimate the drug metabolic fates in vivo. Different approaches are provided and emphasis is placed on the potential of human liver microsomes for drug metabolism and inhibition studies. The methodology for these studies using human liver microsomes Cited by: Drug metabolism studies are essential and necessary during the evaluation of drugs.

It is commonly used to treat a range of conditions, including anxiety, alcohol withdrawal syndrome, benzodiazepine withdrawal syndrome, muscle spasms, seizures, trouble sleeping, and restless legs syndrome. It may also be used to cause memory loss during certain medical Pregnancy category: AU: C, US: D (Evidence of risk).
