Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Enhances GABA-A receptor activity and inhibits glutamate receptors, leading to neuronal hyperpolarization and anesthesia.
Nitrous oxide is an inhalational anesthetic with analgesic, anxiolytic, and amnestic properties. It acts as a non-competitive NMDA receptor antagonist, inhibits GABA-A receptors, and modulates opioid receptors, leading to altered neurotransmission and dissociation.
Induction: 0.5-3% inspired; Maintenance: 0.5-2% inspired.
Inhalation: 25-75% nitrous oxide in oxygen for sedation; 50-70% for anesthesia, titrated to effect.

Context-sensitive half-life: 2-5 minutes after short exposure; prolonged to 30-60 minutes after prolonged administration due to accumulation in fat and muscle. Terminal elimination half-life: 0.5-1 hour.
Terminal elimination half-life is 2–6 minutes (context-sensitive); rapid washout due to low blood solubility and high pulmonary elimination.
Primarily exhaled unchanged via lungs (>95%); <5% metabolized in liver to fluoride ions and other metabolites, which are excreted renally.
Primarily eliminated via lungs as unchanged gas (>99% exhaled); negligible renal (<1%) or biliary/fecal elimination.
