LIDODERM vs SCANDONEST PLAIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Lidocaine is an amide-type local anesthetic that blocks voltage-gated sodium channels (Nav1.7) in nerve cell membranes, inhibiting depolarization and conduction of nerve impulses, thereby producing both local anesthesia and systemic analgesia.
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.
Apply 1 to 3 patches (5% lidocaine) to intact skin over most painful area for up to 12 hours within a 24-hour period; maximum 3 patches at once.
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 is 3–5 hours after topical application; after intravenous administration, half-life is 1.5–2 hours. Clinical context: Systemic accumulation possible with prolonged use on inflamed skin.
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 excretion of metabolites (primarily 4-hydroxy-2,6-xylidine glucuronide) accounts for >85% of elimination; <3% excreted unchanged; biliary/fecal elimination minimal (<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%).
