SERAX vs VERSED
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
SERAX (oxazepam) is a benzodiazepine that modulates GABA-A receptors, enhancing the inhibitory effect of GABA, leading to anxiolytic, sedative, and anticonvulsant effects.
Benzodiazepine that enhances GABA-A receptor activity, increasing chloride ion conductance and causing neuronal hyperpolarization.
Oral: 5-10 mg twice daily; maximum 20 mg/day. Intravenous: 2-5 mg slow IV push, may repeat after 2 hours.
IV: Initial 1-2.5 mg; titrate by 0.5-1 mg every 2-3 min; usual total 2.5-5 mg for sedation. IM: 0.07-0.08 mg/kg (max 5 mg) once. Oral: 7.5-15 mg once (preoperative).

Terminal elimination half-life is 8-15 hours (mean 12 hours) in adults; prolonged in renal impairment.
Terminal elimination half-life: 1.8–2.5 hours in healthy adults; prolonged in elderly (up to 6 hours), obesity (up to 8 hours), hepatic cirrhosis (up to 20 hours), and critically ill patients.
Primarily renal (urinary) as unchanged drug (60-80%) and metabolites (20-40%); less than 5% fecal elimination.
Renal: ~1% unchanged; Hepatic metabolism to glucuronide conjugates and 1-hydroxymidazolam, with subsequent renal elimination of metabolites. Fecal excretion is minimal (<2%).
