Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Lidocaine is a sodium channel blocker that stabilizes neuronal membranes by inhibiting the ionic fluxes required for initiation and conduction of impulses, thereby producing local anesthesia. Dextrose 5% provides caloric support.
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.
Intravenous administration: Initial dose of 1-1.5 mg/kg (up to 300 mg total) given at a rate not exceeding 50 mg/min. Followed by continuous infusion at 1-4 mg/min (20-50 mcg/kg/min) for arrhythmia management.
Adult: 5-25 mL (250-1250 mg lidocaine) of 5% lidocaine with glucose 7.5% solution, administered by caudal or lumbar epidural injection, single dose. Max total dose: 1250 mg.

Terminal elimination half-life: 1.5–2 hours (prolonged to 2–3 hours in hepatic impairment; unchanged in renal impairment).
1.5-2 hours (terminal); prolonged in heart failure, hepatic disease, or elderly; neonates 3-6 hours due to immature hepatic function.
Renal excretion of unchanged drug and metabolites: 10% unchanged, 90% as metabolites (primarily 4-hydroxy-2,6-xylidine and glycylxylidide). Less than 1% biliary/fecal.
Hepatic metabolism (90% N-dealkylation by CYP1A2/CYP3A4 to monoethylglycinexylidide and glycinexylidide); renal excretion of metabolites and parent drug (<10% unchanged); <1% biliary/fecal.
