Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Lidocaine is a sodium channel blocker that inhibits depolarization of cardiac myocytes and nerve axons by binding to voltage-gated sodium channels and stabilizing the neuronal membrane, thereby preventing the propagation of action potentials.
PEDIATRIC LTA KIT contains lidocaine, tetracaine, and epinephrine. Lidocaine and tetracaine are amide and ester local anesthetics, respectively, that block voltage-gated sodium channels, preventing nerve impulse propagation. Epinephrine is a sympathomimetic that causes vasoconstriction, prolonging local anesthetic effect and reducing systemic absorption.
Intravenous infusion: 1-4 mg/min (20-50 mcg/kg/min) for cardiac arrhythmias. Bolus: 1-1.5 mg/kg IV, then infusion.
Not applicable. Pediatric LTA Kit is a topical lidocaine/tetracaine patch for dermal anesthesia. Adult dose: apply one patch to intact skin for 20-30 minutes prior to procedure; remove prior to procedure. Maximum 3 patches per session. Not for systemic use.

Terminal elimination half-life approximately 1.5-2 hours after bolus, prolonged to 2-4 hours in heart failure or hepatic impairment; continuous infusion may show context-sensitive half-life.
2-3 hours (terminal) in children with normal renal function; prolonged in renal impairment
Renal excretion of unchanged drug and metabolites; <10% unchanged in urine, >90% as metabolites (primarily monoethylglycinexylidide and glycinexylidide). Biliary/fecal elimination minimal (<1%).
Renal (95% as unchanged drug), fecal (5%)
