PEDIATRIC LTA KIT vs XYLOCAINE VISCOUS
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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 is an amide-type local anesthetic that blocks voltage-gated sodium channels, inhibiting nerve impulse propagation and reducing pain sensation.
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.
Adults: 5-15 mL orally (or swish and spit) 4-6 times daily, not to exceed 4 doses in 12 hours or 30 mL in 12 hours.

2-3 hours (terminal) in children with normal renal function; prolonged in renal impairment
Terminal elimination half-life: 1.5-2 hours in adults; prolonged in hepatic impairment or heart failure (up to 6-8 hours). In neonates, half-life may be 3-6 hours due to immature metabolism.
Renal (95% as unchanged drug), fecal (5%)
Renal excretion of metabolites: ~90%. Unchanged drug: <10%. Biliary/fecal: minor.
