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).

Midazolam is used to sedate children during extracorporeal membrane oxygenation (ECMO). Pharmacokinetic changes are expected because of extracorporeal circulation and maturation. We present a population pharmacokinetic model for midazolam and its major metabolites in neonates during venoarterial ECMO. We studied

Several studies investigating the interaction of honey and drug-metabolizing enzymes showed controversial results, with some suggesting that honey induces CYP3A-mediated metabolism in mammals and humans. This clinical trial was conducted to determine the effect of repeated honey administration on human
