Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Triazolam is a benzodiazepine that enhances the effect of GABA at the GABA-A receptor, increasing chloride ion conductance and causing neuronal hyperpolarization, leading to CNS depression.
SERAX (oxazepam) is a benzodiazepine that modulates GABA-A receptors, enhancing the inhibitory effect of GABA, leading to anxiolytic, sedative, and anticonvulsant effects.
0.25 mg orally once daily at bedtime, maximum 0.5 mg per day.
Oral: 5-10 mg twice daily; maximum 20 mg/day. Intravenous: 2-5 mg slow IV push, may repeat after 2 hours.

Terminal elimination half-life is 1.5–5.5 hours (mean 2.5 hours). Short half-life minimizes next-day sedation.
Terminal elimination half-life is 8-15 hours (mean 12 hours) in adults; prolonged in renal impairment.
Primarily renal (80%) as conjugated metabolites; fecal (8%); unchanged drug <1%.
Primarily renal (urinary) as unchanged drug (60-80%) and metabolites (20-40%); less than 5% fecal elimination.
