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.
Bupivacaine is an amide-type local anesthetic that blocks voltage-gated sodium channels in nerve cell membranes, reversibly inhibiting nerve impulse propagation, particularly in sensory fibers.
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.
Adults: 0.5% solution infiltrated up to 175 mg (35 mL) for minor procedures; for major procedures, up to 225 mg (45 mL) with epinephrine. Repeat doses at 3-hour intervals. Maximum dose 400 mg with epinephrine.

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 is approximately 2.5 to 3.5 hours in adults; may be prolonged in neonates (8-12 hours) or patients with hepatic impairment.
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.
Primarily hepatic metabolism; less than 5% excreted unchanged in urine. Metabolites are excreted renally, with a small amount in feces via biliary elimination.
