DIASTAT vs DIASTAT ACUDIAL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Diazepam enhances the effect of gamma-aminobutyric acid (GABA) at GABA-A receptors, increasing chloride ion conductance and neuronal hyperpolarization, leading to anxiolytic, sedative, muscle relaxant, and anticonvulsant effects.
Binds to GABA-A receptors, enhancing GABA effects and increasing chloride ion conductance, leading to neuronal hyperpolarization and inhibition of seizure activity.
Adult: 0.2 mg/kg (max 20 mg) rectally as a single dose; may repeat once after 4-12 hours if needed. Maximum cumulative dose: 40 mg per 24-hour period.
2.5 mg to 20 mg rectally, as a single dose for acute seizure clusters; may repeat once after 4-12 hours if needed. Maximum: 20 mg per treatment episode.

30–60 hours for diazepam; nordazepam (active metabolite) 50–120 hours. Prolonged in elderly, liver disease, and neonates
Terminal elimination half-life: 20-50 hours in adults; prolonged in elderly and patients with hepatic impairment (up to 100 hours).
Renal (primarily as glucuronide and sulfate conjugates; <5% unchanged), biliary/fecal minimal
Primarily renal (urinary) as glucuronide conjugates and unchanged drug; <2% excreted unchanged in feces.
