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 agent that inhibits sodium ion influx into nerve cells, blocking nerve conduction and pain sensation.
1 to 2 drops of 0.5% solution topically to the eye, repeated as needed for anesthesia.
Apply one 10 mg/10 cm² transdermal patch to intact skin once daily, typically in the morning; remove after 24 hours and replace with a new patch.

Terminal elimination half-life: 0.4–1.2 minutes (rapid enzymatic hydrolysis by plasma esterases); clinical significance: ultra-short duration limits systemic toxicity.
Terminal elimination half-life is approximately 7–9 hours; clinically, steady-state is achieved after 2–3 days of daily application.
Renal excretion of parent drug and metabolites: <5% unchanged.
Approximately 60% of the dose is excreted renally as unchanged drug and metabolites; the remainder is eliminated via biliary/fecal routes.
