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 a local anesthetic that stabilizes neuronal membranes by inhibiting sodium ion influx, thereby blocking initiation and conduction of nerve impulses.
1 to 2 drops of 0.5% solution topically to the eye, repeated as needed for anesthesia.
1-1.5 mg/kg IV bolus over 2-3 minutes, followed by continuous IV infusion of 1-4 mg/min for ventricular arrhythmias; maximum 3 mg/kg (or 200-300 mg) over 1 hour.

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: 1.5-2 hours (adults); prolonged in heart failure (up to 4-6 hours) or hepatic impairment (up to 5-7 hours).
Renal excretion of parent drug and metabolites: <5% unchanged.
Renal: ~90% as metabolites and <10% unchanged. Biliary/fecal: minor (<1%).
