Metabolite Identification
Common Name4-hydroxyalprazolam
Description4-hydroxyalprazolam belongs to the class of organic compounds known as 1,2,4-triazolo[4,3-a][1,4]benzodiazepines. These are aromatic compounds containing a 1,4-benzodiazepine fused to and sharing a nitrogen atom with a 1,2,4-triazole ring. Alprazolam (trade name Xanax, available among other generic names) is a short-acting anxiolytic of the benzodiazepine class of psychoactive drugs. Alprazolam is extensively metabolized in humans, primarily by cytochrome P450 3A4 (Cyp3A4), to two major metabolites in plasma: 4-hydroxyalprazolam and α- hydroxyalprazolam. 4-hydroxyalprazolam is a moderately basic compound (based on its pKa). 4-Hydroxyalprazolam is a metaboltie of Alprazolam.
