General description

α-Hydroxymidazolam is an active, major metabolite in urine and blood of the benzodiazepine, midazolam. Midazolam is sold as Dormicum, Hypnovel®, and Versed as a sedative and treatment for insomnia and seizures. This Certified Spiking Solution® is suitable for use as starting material in calibrators or controls for a variety of LC/MS or GC/MS applications from forensic analysis and clinical toxicology to urine drug testing.

Application


  • α-Hydroxymidazolam solution in pharmacokinetic studies: The application of α-Hydroxymidazolam solution is crucial in pharmacokinetic research to study the metabolism of midazolam, particularly its phase I metabolic pathways, providing essential data on the drug′s biotransformation and clearance rates in humans (Bourget et al., 1996).

  • α-Hydroxymidazolam as a benzodiazepine metabolite standard: Utilized as a benzodiazepine metabolite standard, α-Hydroxymidazolam aids in the accurate measurement of midazolam and its metabolites in plasma using high-performance liquid chromatography, essential for ensuring dosing efficacy and safety in clinical settings (Lee and Charles, 1996).

The allosteric effect of fluconazole (effector) on the formation of 1'-hydroxymidazolam (1'-OH-MDZ) and 4-hydroxymidazolam (4-OH-MDZ) from midazolam (MDZ), a substrate of CYP3A4/5--members of the cytochrome P450 superfamily of enzymes--was examined in healthy volunteers. Following pretreatment with fluconazole, the ratio of

Controversy exists concerning the sex-dependent differences in cytochrome P450 3A activity in humans. Meta-analysis of selected studies may address this question. Meta-analysis was performed on published or unpublished data in terms of sex-dependent differences in midazolam (MDZ) disposition in humans.
