Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Local anesthetic that stabilizes the neuronal membrane by inhibiting the influx of sodium ions, thereby blocking nerve impulse propagation.
SENSORCAINE (bupivacaine) is an amide-type local anesthetic that blocks sodium ion channels in nerve cell membranes, thereby inhibiting depolarization and propagation of action potentials, resulting in reversible local anesthesia.
100 mg orally every 12 hours
Epidural or caudal block: 15-30 mL of 0.5% to 1% solution (75-150 mg) every 2-4 hours as needed. Maximum single dose: 225 mg.

Terminal elimination half-life approximately 1.5-2.0 hours in adults; prolonged to 3-5 hours in hepatic impairment and neonates.
The terminal elimination half-life of bupivacaine is approximately 2.7 hours in adults (range 1.5–5.5 hours). In neonates, the half-life is significantly prolonged (~8–12 hours) due to immature hepatic function, leading to an increased risk of toxicity.
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.
SENSORCAINE (bupivacaine) is primarily metabolized in the liver via conjugation with glucuronic acid and undergoes hepatic dealkylation. Approximately 6% of the drug is excreted unchanged in the urine. The majority of the dose (about 95%) is excreted as metabolites in the urine (<10% unchanged) and the remainder in feces via biliary elimination.
