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.
Local anesthetic that reversibly blocks sodium ion channels in neuronal membranes, preventing the generation and propagation of action potentials.
1 to 2 drops of 0.5% solution topically to the eye, repeated as needed for anesthesia.
1–2% solution via local infiltration or nerve block, up to a maximum of 4.5 mg/kg (or 300 mg) without epinephrine; with epinephrine, maximum 7 mg/kg (or 500 mg).

Terminal elimination half-life: 0.4–1.2 minutes (rapid enzymatic hydrolysis by plasma esterases); clinical significance: ultra-short duration limits systemic toxicity.
Terminal half-life 2.5-3.5 hours in adults; prolonged to 4-6 hours in hepatic impairment or elderly.
Renal excretion of parent drug and metabolites: <5% unchanged.
Primarily renal excretion of unchanged drug and metabolites (70-80%); minor biliary elimination (10-15%); fecal excretion <5%.
