LIDOPEN vs SCANDONEST PLAIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Lidocaine is a sodium channel blocker, stabilizing neuronal membranes by inhibiting the influx of sodium ions, thereby preventing the propagation of action potentials and producing local anesthesia.
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 2% topical gel: Apply 1-2 grams (approximately 5-10 cm ribbon) to affected area every 4-6 hours as needed, not to exceed 5 grams per day. For infiltration anesthesia: 1% solution, 0.5-5 mL injected locally; maximum 4.5 mg/kg.
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.

1.5–2 hours (terminal); prolonged in hepatic impairment
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 (10% unchanged; 80% as metabolites), biliary/fecal (10%)
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%).
