Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Lidocaine is an amide-type local anesthetic that acts by blocking voltage-gated sodium channels in neuronal cell membranes, thereby inhibiting the initiation and conduction of nerve impulses. This stabilizes the neuronal membrane and produces a reversible loss of sensation.
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: 1-1.5 mg/kg bolus, followed by 1-4 mg/min continuous infusion for ventricular arrhythmias. Max dose: 3 mg/kg bolus, 4 mg/min 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 is approximately 1.5–2.0 hours after a single IV dose. In patients with heart failure or hepatic impairment, it may be prolonged to >3 hours. After continuous infusion, the half-life may increase due to accumulation.
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.
Lidocaine is primarily metabolized in the liver by CYP1A2 and CYP3A4 to active metabolites (MEGX, GX). Less than 10% is excreted unchanged in urine. Renal excretion accounts for about 20% of total clearance as metabolites and parent drug; fecal elimination is minimal (<5%).
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.
