Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Lidocaine stabilizes the neuronal membrane by inhibiting sodium ion influx through voltage-gated sodium channels, thereby blocking the initiation and propagation of action potentials, resulting in local anesthesia.
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.
Maximum 4.5 mg/kg (not to exceed 300 mg) via subcutaneous infiltration, epidural, or nerve block; repeat dosing after 30 minutes if needed.

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.
Terminal elimination half-life: ~1.5–2 hours (adults). Prolonged in hepatic impairment, congestive heart failure, or neonates.
Renal (metabolites: 4-hydroxyxylidine, glycylxylidide, monoethylglycinexylidide; <10% unchanged). Biliary/fecal negligible.
Renal: ~90% as metabolites (mostly 4-hydroxy-2,6-xylidine and conjugates); <10% unchanged. Biliary/fecal: minor.
