LIDOPEN vs SCANDONEST L
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 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.
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 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.

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