Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Enhances GABA-A receptor activity, increasing chloride ion conductance and causing central nervous system depression.
Enhances gamma-aminobutyric acid (GABA) activity at GABA-A receptors, prolonging chloride channel opening and inhibiting neuronal firing.
Oral: 50-100 mg 3-4 times daily; maximum 600 mg daily.
Induction of anesthesia: 100-150 mg IV given over 30-60 seconds; additional increments of 25-50 mg as needed. Hypnotic/sedative: 100-300 mg IM or 150-200 mg PO at bedtime. Anticonvulsant in emergencies: 5-7 mg/kg IV slow push over 1-2 minutes, may repeat every 15-30 minutes up to a maximum of 1 g. Rectal administration: 120-200 mg as a single dose for sedation.

Terminal elimination half-life: 40-70 hours (mean 60 h) in adults; prolonged in elderly, hepatic impairment, and neonates (up to 100 h). Clinical context: Accumulation occurs with repeated dosing.
Terminal elimination half-life of 20-30 hours in adults. In prolonged ICU sedation, context-sensitive half-life can extend significantly (up to 50-100 hours) due to redistribution and accumulation.
Primarily hepatic metabolism (80%) with renal excretion of inactive metabolites (<30% unchanged). Less than 1% excreted in feces.
Primarily renal excretion of inactive metabolites (hepatic metabolism via CYP). Approximately 25-50% unchanged in urine at alkaline pH; biliary/fecal elimination minimal (<5%).
