General description

1′-Hydroxymidazolam is the metabolite of midazolam.

Application

1′-Hydroxymidazolam (1′-OHMDZ) can be used for assessing Cyp3a11 enzyme activity as well as for pharmacokinetic (PK) study of midazolam.
CYP3A4 metabolite of midazolam.

Biochem/physiol Actions

1′-Hydroxymidazolam is the major hydroxylated metabolite of Midazolam (MDZ), forms due to rapid and extensive metabolization of MDZ by the CYP 450 3A isoenzymes in the liver. The product contributes to the pharmacological impact of MDZ.
