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 as starting material for use 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


  • Pharmacodynamic studies: α-Hydroxymidazolam is utilized in pharmacodynamic research to compare the effects of midazolam and its metabolites on neuronal activity. The study provides insight into the depressant effects on the neocortical neuronal network, aiding in the understanding of benzodiazepine drug actions (Balk et al., 2017).

  • Metabolic pathway research: Research explores the use of α-Hydroxymidazolam in studying drug-drug interactions and metabolism in cytochrome P450 knockout mice. This application highlights its role in examining metabolic pathways and interactions that affect drug metabolism, crucial for drug development and therapy optimization (Grimsley et al., 2013).

The metabolic conversion of midazolam (MDZ) to its main metabolite 1'-hydroxy-midazolam (1-OH-MDZ) can be used as a probe drug for cytochrome P450 3A (CYP3A) activity. A sensitive method for the simultaneous determination of MDZ and its metabolite 1-OH-MDZ in human

In order to simultaneously determine in vivo P-glycoprotein (P-gp) and Cytochrome P450 3A (CYP3A) activity, a new, rapid and sensitive liquid chromatography/tandem mass spectrometry (LC-MS/MS) method has been developed and fully validated to simultaneously determine midazolam (MDZ, as CYP3A substrate)

Midazolam metabolic clearance to 1'-hydroxymidazolam is an accurate measure of CYP3A activity which requires extensive plasma and urine sampling. The objective of this study was to find a new limited sampling strategy (LSS) to predict midazolam metabolic clearance to 1'-hydroxymidazolam
