Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Local anesthetic that stabilizes the neuronal membrane by inhibiting sodium ion influx, thereby blocking nerve impulse transmission.
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 to 2 drops of 0.5% solution topically to the eye, repeated as needed for anesthesia.
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: 0.4–1.2 minutes (rapid enzymatic hydrolysis by plasma esterases); clinical significance: ultra-short duration limits systemic toxicity.
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 parent drug and metabolites: <5% unchanged.
Hepatic metabolism (90% N-dealkylation by CYP1A2/CYP3A4 to monoethylglycinexylidide and glycinexylidide); renal excretion of metabolites and parent drug (<10% unchanged); <1% biliary/fecal.
