LIDOCAINE vs SCANDONEST L
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Lidocaine is a sodium channel blocker that inhibits the influx of sodium ions into cardiac Purkinje fibers and myocytes, thereby stabilizing the neuronal membrane and decreasing automaticity. It also exhibits local anesthetic effects by reversibly binding to voltage-gated sodium channels in nerve cell membranes, blocking impulse conduction.
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.
For ventricular arrhythmias: IV bolus 1-1.5 mg/kg, then continuous infusion 1-4 mg/min. For local anesthesia: 0.5-2% solution, max 4.5 mg/kg (300 mg) without epinephrine, 7 mg/kg (500 mg) with epinephrine.
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.

"The metabolism of Tenofovir disoproxil can be decreased when combined with Lidocaine."
Clinical Note
moderateLidocaine + Sulfisoxazole
"The metabolism of Sulfisoxazole can be decreased when combined with Lidocaine."
Clinical Note
moderateLidocaine + Erythromycin
Terminal elimination half-life 1.5-2 hours (normal hepatic function). In CHF or hepatic impairment, prolonged to 6-8 hours; in neonates, 3-6 hours. Context: rapid redistribution after IV bolus (alpha half-life ~8 min) accounts for brief clinical effect, while terminal half-life determines accumulation with infusion.
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 excretion of metabolites: 4-hydroxyxylidine (70-80% renal, 10-20% biliary/fecal), unchanged lidocaine <10% renal. Total renal elimination ~90% (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.
