Definition
ChEBI: A 1,4-benzodiazepinone that is 1,3-dihydro-2H-1,4-benzodiazepin-2-one substituted by a chloro group at position 7, a hydroxy group at position 3 and phenyl group at position 5.
Allgemeine Beschreibung
Oxazepam, 7-chloro-1,3-dihydro-3-hydroxy-5-phenyl-2H-1,4-benzodiazpin-2-one (Serax), isan active metabolite of both chlordiazepoxide and diazepamand can be considered a prototype for the 3-hydroxy benzo-diazepines. It is much more polar than diazepam. Oxazepam is rapidlyinactivated to glucuronidated metabolites that are excretedin the urine. Thus, the half-life of oxazepam is about 4 to 8hours, and it is marketed as a short-acting anxiolytic. As aresult, its cumulative effects with chronic therapy are muchless than with long-acting benzodiazepine such as chlordiazepoxideand diazepam.
Air & Water Reaktionen
Insoluble in water.
Reaktivität anzeigen
OXAZEPAM is stable in light and is non hygroscopic. OXAZEPAM is stable in neutral solution. OXAZEPAM is hydrolyzed by acids and bases.
Brandgefahr
Flash point data for OXAZEPAM are not available; however, OXAZEPAM is probably combustible.
Pharmakokinetik
The half-life of oxazepam is approximately 4 to 8 hours, and cumulative effects with chronic therapy
are much less than with long-acting benzodiazepines, such as chlordiazepoxide and diazepam. Lorazepam is the
2′-chloro derivative of oxazepam and has a similarly short half-life (2–6 hours) and pharmacological activity.
Stoffwechsel
Oxazepam is an active metabolite of both chlordiazepoxide and diazepam and is marketed separately, as a shortacting anxiolytic agent. Oxazepam is rapidly inactivated to glucuronidated metabolites that are excreted in the urine.
