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.
Local anesthetic that stabilizes the neuronal membrane by inhibiting the influx of sodium ions, thereby blocking nerve impulse propagation.
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.

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 approximately 1.5-2.0 hours in adults; prolonged to 3-5 hours in hepatic impairment and neonates.
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.
Hepatic metabolism to 2,6-xylidine and 4-hydroxy-2,6-xylidine; <10% excreted unchanged in urine; approximately 70-80% of metabolites excreted renally, with <5% in feces.
