Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Lidocaine is a sodium channel blocker that inhibits depolarization of cardiac myocytes and nerve axons by binding to voltage-gated sodium channels and stabilizing the neuronal membrane, thereby preventing the propagation of action potentials.
Scandonest L (mepivacaine hydrochloride) is an amide-type local anesthetic that stabilizes neuronal membranes by inhibiting sodium ion influx across the membrane, thereby blocking nerve impulse initiation and conduction.
Intravenous infusion: 1-4 mg/min (20-50 mcg/kg/min) for cardiac arrhythmias. Bolus: 1-1.5 mg/kg IV, then infusion.
Dental infiltration or nerve block: 1.3 mL of 3% solution (isocaine) per site; maximum 9 mg/kg (0.3 mL/kg) per session. Infiltration: 0.5-1.0 mL; nerve block: 1.0-1.3 mL.

Terminal elimination half-life approximately 1.5-2 hours after bolus, prolonged to 2-4 hours in heart failure or hepatic impairment; continuous infusion may show context-sensitive half-life.
Terminal elimination half-life is 1.5–2.0 hours in healthy adults; prolonged to 3–5 hours in patients with hepatic impairment or severe renal disease.
Renal excretion of unchanged drug and metabolites; <10% unchanged in urine, >90% as metabolites (primarily monoethylglycinexylidide and glycinexylidide). Biliary/fecal elimination minimal (<1%).
Primarily hepatic metabolism (approx. 90%) via amidase hydrolysis and aromatic hydroxylation; renal excretion of unchanged drug accounts for <5% of the dose; less than 1% excreted in feces.
