LIDOSITE TOPICAL SYSTEM KIT vs XYLOCAINE VISCOUS
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Lidocaine is an amide-type local anesthetic that stabilizes neuronal membranes by blocking voltage-gated sodium channels, thereby inhibiting the initiation and conduction of nerve impulses.
Lidocaine is an amide-type local anesthetic that blocks voltage-gated sodium channels, inhibiting nerve impulse propagation and reducing pain sensation.
Apply up to 3 patches topically once daily for up to 12 hours per day. Maximum 3 patches (210 mg lidocaine) per day.
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.

1.5-2 hours (terminal); prolonged in hepatic dysfunction or heart failure
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 (80-90% as metabolites, <10% unchanged), biliary/fecal (minor, <5%)
Renal excretion of metabolites: ~90%. Unchanged drug: <10%. Biliary/fecal: minor.
