NESACAINE vs PEDIATRIC LTA KIT
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Nesacaine (chloroprocaine) is an ester-type local anesthetic that blocks voltage-gated sodium channels in neuronal membranes, inhibiting the initiation and conduction of nerve impulses.
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.
Injectable local anesthetic: 1% or 2% solution, maximum dose 7 mg/kg (not to exceed 500 mg) with epinephrine, 4.5 mg/kg (not to exceed 300 mg) without epinephrine. Administer by infiltration or nerve block; may repeat at 30-minute intervals.
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 half-life: 40-60 minutes (rapidly metabolized by plasma pseudocholinesterase); clinical context: prolonged with hepatic dysfunction or atypical pseudocholinesterase
2-3 hours (terminal) in children with normal renal function; prolonged in renal impairment
Renal: 90-95% as unchanged drug and metabolites (predominantly 4-hydroxypropycaine); biliary/fecal: <5%
