Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Local anesthetic agent that inhibits sodium ion influx into nerve cells, blocking nerve conduction and pain sensation.
Bupivacaine blocks sodium ion channels in nerve cell membranes, inhibiting the generation and propagation of action potentials, resulting in local anesthesia.
Apply one 10 mg/10 cm² transdermal patch to intact skin once daily, typically in the morning; remove after 24 hours and replace with a new patch.
Local infiltration: 0.25-0.5% solution, up to 30 mL; peripheral nerve block: 0.25-0.5% solution, 30-40 mL; epidural: 0.5-0.75% solution, 15-30 mL. Maximum dose: 2 mg/kg (with epinephrine), 1.5 mg/kg (without epinephrine).

Terminal elimination half-life is approximately 7–9 hours; clinically, steady-state is achieved after 2–3 days of daily application.
Terminal elimination half-life: 2.5-4 hours in adults (longer in neonates and hepatic impairment; up to 8-12 hours). Clinically, accumulation occurs with continuous infusion or repeated doses.
Approximately 60% of the dose is excreted renally as unchanged drug and metabolites; the remainder is eliminated via biliary/fecal routes.
Renal excretion of metabolites (approximately 90-95% as para-aminobenzoic acid and other metabolites); less than 5% unchanged in urine. Biliary/fecal excretion is minimal.
