NAYZILAM vs SERAX
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Nayzilam (midazolam) is a benzodiazepine that enhances the effect of the neurotransmitter gamma-aminobutyric acid (GABA) at the GABA-A receptor, resulting in increased chloride ion conductance, neuronal hyperpolarization, and inhibition of neuronal activity.
SERAX (oxazepam) is a benzodiazepine that modulates GABA-A receptors, enhancing the inhibitory effect of GABA, leading to anxiolytic, sedative, and anticonvulsant effects.
5 mg intranasally as a single dose; may repeat once after 10 minutes if needed. Maximum 10 mg per episode.
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 of midazolam is 1.5–2.5 hours, but for NAYZILAM (midazolam nasal spray) the effective half-life for anticonvulsant effect is approximately 2–3 hours due to prolonged absorption; clinical context: used for seizure clusters, duration of effect may persist for 4–6 hours.
Terminal elimination half-life is 8-15 hours (mean 12 hours) in adults; prolonged in renal impairment.
Renal excretion as metabolites (primarily glucuronide conjugates) and unchanged drug; approximately 15% recovered in urine as unchanged midazolam, with the remainder as metabolites; <1% excreted in feces via biliary elimination.
Primarily renal (urinary) as unchanged drug (60-80%) and metabolites (20-40%); less than 5% fecal elimination.
