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.
Blocks voltage-gated sodium channels, inhibiting action potential propagation in neurons and cardiac myocytes.
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.
1-1.5 mg/kg IV bolus, then 0.5-0.75 mg/kg IV bolus every 5-10 min to a max of 3 mg/kg total loading dose; maintenance infusion 1-4 mg/min IV. For epidural: 5-10 mL of 1-2% solution.

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 hours (single dose); prolonged to 2–3 hours with repeated dosing or in heart failure, liver disease, or elderly. Context: Effective for 1–2 hours after IV bolus, requiring infusion for sustained 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 excretion of unchanged drug and metabolites: ~90% as metabolites (e.g., monoethylglycinexylidide, glycinexylidide), <10% unchanged. Biliary/fecal: minimal (<1%).
