Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Blocks voltage-gated sodium channels, inhibiting action potential propagation in neurons and cardiac myocytes.
Lidocaine is an amide-type local anesthetic that stabilizes the neuronal membrane by inhibiting sodium ion channels, thereby blocking the initiation and conduction of nerve impulses.
1-1.5 mg/kg IV bolus, then 0.5-0.75 mg/kg IV bolus every 5-10 min to a max of 3 mg/kg total loading dose; maintenance infusion 1-4 mg/min IV. For epidural: 5-10 mL of 1-2% solution.
Adult: 5-25 mL (250-1250 mg lidocaine) of 5% lidocaine with glucose 7.5% solution, administered by caudal or lumbar epidural injection, single dose. Max total dose: 1250 mg.

Terminal elimination half-life: 1.5–2 hours (single dose); prolonged to 2–3 hours with repeated dosing or in heart failure, liver disease, or elderly. Context: Effective for 1–2 hours after IV bolus, requiring infusion for sustained effect.
1.5-2 hours (terminal); prolonged in heart failure, hepatic disease, or elderly; neonates 3-6 hours due to immature hepatic function.
Renal excretion of unchanged drug and metabolites: ~90% as metabolites (e.g., monoethylglycinexylidide, glycinexylidide), <10% unchanged. Biliary/fecal: minimal (<1%).
Hepatic metabolism (90% N-dealkylation by CYP1A2/CYP3A4 to monoethylglycinexylidide and glycinexylidide); renal excretion of metabolites and parent drug (<10% unchanged); <1% biliary/fecal.
