Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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. It exhibits antiarrhythmic activity by suppressing automaticity and conduction in cardiac tissues.
Lidocaine is an amide-type local anesthetic that blocks voltage-gated sodium channels, inhibiting nerve impulse propagation and reducing pain sensation.
Antiarrhythmic: 1-1.5 mg/kg IV bolus, may repeat 0.5-0.75 mg/kg in 5-10 minutes; maximum total 3 mg/kg. Followed by continuous IV infusion 1-4 mg/min. Local anesthesia: maximum 4.5 mg/kg (300 mg) without epinephrine; 7 mg/kg (500 mg) with epinephrine.
Adults: 5-15 mL orally (or swish and spit) 4-6 times daily, not to exceed 4 doses in 12 hours or 30 mL in 12 hours.

Terminal elimination half-life: 1.5–2 hours (normal cardiac output and hepatic function). Prolonged in heart failure (up to 10 hours), hepatic disease (up to 5–15 hours), and with continuous infusion (due to saturable metabolism).
Terminal elimination half-life: 1.5-2 hours in adults; prolonged in hepatic impairment or heart failure (up to 6-8 hours). In neonates, half-life may be 3-6 hours due to immature metabolism.
Renal: ~90% as metabolites (including monoethylglycinexylidide [MEGX] and glycinexylidide [GX]) and ~10% unchanged. Biliary/fecal: <3%.
Renal excretion of metabolites: ~90%. Unchanged drug: <10%. Biliary/fecal: minor.
