LIDOCATON vs SCANDONEST L
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 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: Initial IV bolus 1-1.5 mg/kg, then IV infusion 1-4 mg/min. Adjust for arrhythmia suppression.
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.

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 is 1.5–2.0 hours in healthy adults; prolonged to 3–5 hours in patients with hepatic impairment or severe renal disease.
Renal: ~90% as metabolites (major metabolite 4-hydroxyxylidine) and ~10% unchanged. Biliary/fecal: <5%.
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.
