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 neuronal membranes by blocking voltage-gated sodium channels, thereby inhibiting the initiation and conduction of nerve impulses.
1 to 2 drops of 0.5% solution topically to the eye, repeated as needed for anesthesia.
Apply up to 3 patches topically once daily for up to 12 hours per day. Maximum 3 patches (210 mg lidocaine) per day.

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 hepatic dysfunction or heart failure
Renal excretion of parent drug and metabolites: <5% unchanged.
Renal (80-90% as metabolites, <10% unchanged), biliary/fecal (minor, <5%)
