Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Lidocaine is a sodium channel blocker that stabilizes neuronal membranes by inhibiting the ionic fluxes required for initiation and conduction of impulses, thereby producing local anesthesia. Dextrose 5% provides caloric support.
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 administration: Initial dose of 1-1.5 mg/kg (up to 300 mg total) given at a rate not exceeding 50 mg/min. Followed by continuous infusion at 1-4 mg/min (20-50 mcg/kg/min) for arrhythmia management.
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: 1.5–2 hours (prolonged to 2–3 hours in hepatic impairment; unchanged in renal impairment).
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, 90% as metabolites (primarily 4-hydroxy-2,6-xylidine and glycylxylidide). Less than 1% biliary/fecal.
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.
