LIDOCATON vs SCANDONEST PLAIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Lidocaine is a class IB antiarrhythmic agent that blocks voltage-gated sodium channels, inhibiting the inward sodium current, thereby stabilizing cardiac membranes, decreasing automaticity, and increasing the fibrillation threshold. It also acts as a local anesthetic by reversibly blocking nerve impulse propagation.
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.
Lidocaine: Initial IV bolus 1-1.5 mg/kg, then IV infusion 1-4 mg/min. Adjust for arrhythmia suppression.
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 half-life 1.5–2 hours (adults); prolonged in heart failure (up to 4–6 hours) or hepatic impairment (up to 8 hours).
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 (major metabolite 4-hydroxyxylidine) and ~10% unchanged. Biliary/fecal: <5%.
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%).
