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 an amide-type local anesthetic that stabilizes the neuronal membrane by inhibiting sodium ion channels, thereby blocking the initiation and conduction of nerve impulses. It also has antiarrhythmic properties by decreasing automaticity in Purkinje fibers and suppressing ventricular arrhythmias.
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.
Intrathecal administration for spinal anesthesia: 50-100 mg (1.5-2 mL of 5% solution) as a single dose. For continuous epidural or peripheral nerve block, 0.8% solution with dextrose 5% is not typically used; refer to 1-2% lidocaine without dextrose for continuous infusion.

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 (adults); prolonged in heart failure (up to 5-8 hours) or hepatic impairment (up to 10-15 hours). Clinically, context indicates redistribution half-life ~8 minutes.
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 (metabolites: 4-hydroxyxylidine, glycylxylidide, monoethylglycinexylidide; <10% unchanged). Biliary/fecal negligible.
