Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Noncompetitive NMDA receptor antagonist; blocks glutamate binding, and modulates opioid receptors, monoaminergic receptors, and voltage-gated calcium channels.
Propofol enhances the activity of gamma-aminobutyric acid (GABA) at GABA-A receptors, leading to increased chloride conductance, neuronal hyperpolarization, and anesthetic effects. It also inhibits N-methyl-D-aspartate (NMDA) receptors and modulates calcium influx via L-type calcium channels.
Induction: 1-2 mg/kg IV; Maintenance: 0.5-1 mg/kg IV or 10-30 mcg/kg/min IV infusion; Subanesthetic: 0.1-0.5 mg/kg IV; Analgesic: IM 2-4 mg/kg; Intranasal 1-3 mg/kg. Frequency: single doses or continuous infusion per clinical need.
Induction: 2-2.5 mg/kg IV bolus. Maintenance: 25-75 mcg/kg/min IV infusion. For sedation: 25-100 mcg/kg/min IV.

Terminal elimination half-life: 2–4 hours (alpha: 10–15 min, beta: 2.5–4 hr); prolonged in hepatic impairment and with repeated dosing (up to 12–24 hr for active metabolite norketamine).
Terminal elimination half-life: 4-7 hours (after prolonged infusion, context-sensitive half-life increases up to 60 minutes after 8-hour infusion).
Renal: 90% as metabolites (norketamine, dehydronorketamine, hydroxylated derivatives) and 4% unchanged; biliary/fecal: 3%; minor pulmonary exhalation.
Renal: <1% unchanged; hepatic metabolism to inactive glucuronide and sulfate conjugates, excreted renally (≈88%) and fecally (≈1-2%).
