Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Lidocaine is an amide-type local anesthetic that stabilizes neuronal membranes by blocking voltage-gated sodium channels, thereby inhibiting the initiation and conduction of nerve impulses. It exhibits antiarrhythmic activity by suppressing automaticity and conduction in cardiac tissues.
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.
Antiarrhythmic: 1-1.5 mg/kg IV bolus, may repeat 0.5-0.75 mg/kg in 5-10 minutes; maximum total 3 mg/kg. Followed by continuous IV infusion 1-4 mg/min. Local anesthesia: maximum 4.5 mg/kg (300 mg) without epinephrine; 7 mg/kg (500 mg) with epinephrine.
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: 1.5–2 hours (normal cardiac output and hepatic function). Prolonged in heart failure (up to 10 hours), hepatic disease (up to 5–15 hours), and with continuous infusion (due to saturable metabolism).
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: ~90% as metabolites (including monoethylglycinexylidide [MEGX] and glycinexylidide [GX]) and ~10% unchanged. Biliary/fecal: <3%.
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%).
