Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Lidocaine is a sodium channel blocker, which stabilizes neuronal membranes and inhibits the initiation and conduction of nerve impulses. Dextrose 5% provides caloric support.
Lidocaine is a class IB antiarrhythmic agent that blocks voltage-gated sodium channels, inhibiting the inward sodium current, thereby stabilizing cardiac membranes, decreasing automaticity, and increasing the fibrillation threshold. It also acts as a local anesthetic by reversibly blocking nerve impulse propagation.
Intravenous: 50-100 mg bolus (1-2 mg/kg) over 2-3 minutes, followed by continuous infusion at 1-4 mg/min (20-50 mcg/kg/min). Total maximum dose: 300 mg over 1 hour.
Lidocaine: Initial IV bolus 1-1.5 mg/kg, then IV infusion 1-4 mg/min. Adjust for arrhythmia suppression.

Terminal elimination half-life: 1.5–2.0 hours in adults with normal hepatic function. In patients with hepatic impairment or heart failure, half-life may be prolonged (>3 hours). Clinical context: short half-life requires continuous infusion for sustained antiarrhythmic effect.
Terminal half-life 1.5–2 hours (adults); prolonged in heart failure (up to 4–6 hours) or hepatic impairment (up to 8 hours).
Renal: approximately 10% unchanged; hepatic metabolism to 4-hydroxy-2,6-xylidine and glycylxylidide, which are excreted renally. Total renal excretion of metabolites and parent drug accounts for >95% of the dose. Fecal excretion is minimal (<5%).
Renal: ~90% as metabolites (major metabolite 4-hydroxyxylidine) and ~10% unchanged. Biliary/fecal: <5%.
