Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Liposomal bupivacaine is a local anesthetic that blocks sodium channels in nerve cell membranes, inhibiting nerve impulse conduction and providing prolonged analgesia.
Scandonest Plain (mepivacaine) is an amide-type local anesthetic that stabilizes neuronal membranes by binding to voltage-gated sodium channels, inhibiting sodium influx and blocking nerve impulse conduction.
Local infiltration: up to 266 mg (20 mL) as a single dose; interscalene brachial plexus block: up to 133 mg (10 mL); femoral nerve block: up to 133 mg (10 mL). Maximum dose 266 mg. Administer via slow injection with frequent aspiration.
Dental infiltration: 1-2 mL (20-40 mg mepivacaine). Nerve block: 2-4 mL (40-80 mg). Max dose: 400 mg (approx 7 mg/kg). Do not repeat within 2 hours.

Terminal elimination half-life is 12-48 hours (mean ~24 hours), reflecting prolonged release from the multivesicular liposome depot.
Terminal elimination half-life: 1.9–3.2 hours in healthy adults; prolonged to 6–8 hours in hepatic impairment or severe renal disease; clinically meaningful for redosing intervals.
Renal (approximately 96% as metabolites, <10% unchanged). Biliary/fecal excretion is negligible.
Renal excretion of unchanged drug and metabolites accounts for >95% of elimination; approximately 80% as unchanged mepivacaine and 15% as N-demethylated metabolites; biliary/fecal excretion minimal (<5%).
