Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Isocaine hydrochloride is a local anesthetic that stabilizes neuronal membranes by blocking voltage-gated sodium channels, thereby inhibiting the initiation and propagation of action potentials.
Lidocaine is a sodium channel blocker, which stabilizes neuronal membranes and inhibits the initiation and conduction of nerve impulses. Dextrose 5% provides caloric support.
1-2% solution infiltrated subcutaneously or locally, maximum dose 4.5 mg/kg (with epinephrine) or 3.0 mg/kg (without epinephrine), not to exceed 300 mg.
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.

Terminal elimination half-life is approximately 2.5 hours in healthy adults. In patients with hepatic impairment, half-life may be prolonged to 6–8 hours; in severe renal impairment, half-life may extend to 4–6 hours.
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.
Renal: Approximately 90% of the dose is excreted as metabolites (primarily conjugated with glucuronic acid) in urine. Fecal: About 10% eliminated unchanged or as metabolites in feces. Biliary excretion is negligible.
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%).
