Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Local anesthetic agent that inhibits sodium ion influx into nerve cells, blocking nerve conduction and pain sensation.
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. It also has antiarrhythmic properties by decreasing automaticity in Purkinje fibers and suppressing ventricular arrhythmias.
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.
Intrathecal administration for spinal anesthesia: 50-100 mg (1.5-2 mL of 5% solution) as a single dose. For continuous epidural or peripheral nerve block, 0.8% solution with dextrose 5% is not typically used; refer to 1-2% lidocaine without dextrose for continuous infusion.

Terminal elimination half-life is approximately 7–9 hours; clinically, steady-state is achieved after 2–3 days of daily application.
Terminal elimination half-life: 1.5-2 hours (adults); prolonged in heart failure (up to 5-8 hours) or hepatic impairment (up to 10-15 hours). Clinically, context indicates redistribution half-life ~8 minutes.
Approximately 60% of the dose is excreted renally as unchanged drug and metabolites; the remainder is eliminated via biliary/fecal routes.
Renal (metabolites: 4-hydroxyxylidine, glycylxylidide, monoethylglycinexylidide; <10% unchanged). Biliary/fecal negligible.
