Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Local anesthetic that stabilizes the neuronal membrane by inhibiting the influx of sodium ions, thereby blocking nerve impulse propagation.
Lidocaine is an amide-type local anesthetic that blocks voltage-gated sodium channels, inhibiting nerve impulse propagation and reducing pain sensation.
100 mg orally every 12 hours
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.

Terminal elimination half-life approximately 1.5-2.0 hours in adults; prolonged to 3-5 hours in hepatic impairment and neonates.
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.
Hepatic metabolism to 2,6-xylidine and 4-hydroxy-2,6-xylidine; <10% excreted unchanged in urine; approximately 70-80% of metabolites excreted renally, with <5% in feces.
Renal excretion of metabolites: ~90%. Unchanged drug: <10%. Biliary/fecal: minor.
