n. a short-acting benzodiazepine that is the final active product of the metabolism of diazepam. Oxazepam possesses the advantage of having no metabolic products; it therefore has a predictable half-life and elimination time and requires minimal processing in the liver. Because of this, some consider it to be the preferred agent in the management of alcohol withdrawal. However, the need for close monitoring of dosing schedules leads others to prefer longer-acting agents for this condition. U.S. trade name: Serax.
