LIDOPEN vs PEDIATRIC LTA KIT
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.
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.
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.
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.
