Xinping Xue et al.
Journal of pharmaceutical and biomedical analysis, 55(1), 187-193 (2011-02-15)
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)
Camilla Svanström et al.
Journal of pharmaceutical and biomedical analysis, 58, 71-77 (2011-10-14)
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

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

The aim of the present study was to determine an index to evaluate the efficacy and safety of midazolam (MDZ) to treat status epilepticus (SE). An original system was therefore developed to measure blood concentrations of MDZ and 1-hydroxymidazolam (1-OHMDZ)

Midazolam, a potent benzodiazepine derivative and a typical substrate of CYP3A4/3A5, is essentially metabolized in human into 1'-hydroxymidazolam, then eliminated as the corresponding phase II metabolite, the 1'-O-β-D-glucuronide derivative. A high yield alternative to the current multistep synthesis of 1'-hydroxymidazolam
