NESACAINE-MPF vs XYLOCAINE VISCOUS
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Nesacaine-MPF (chloroprocaine) is an ester-type local anesthetic that stabilizes neuronal membranes by inhibiting sodium ion influx, thereby blocking impulse conduction in nerve fibers.
Lidocaine is an amide-type local anesthetic that blocks voltage-gated sodium channels, inhibiting nerve impulse propagation and reducing pain sensation.
1% solution: 2.5-30 mL (25-300 mg) subcutaneously or locally; maximum 30 mL per dose. 2% solution: 1.25-15 mL (25-300 mg) subcutaneously or locally; maximum 15 mL per dose.
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 half-life: 3-4 hours (adults); prolonged in hepatic or 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 excretion of metabolites; <10% unchanged drug. Biliary/fecal elimination minor.
Renal excretion of metabolites: ~90%. Unchanged drug: <10%. Biliary/fecal: minor.
