LIDOCAINE HYDROCHLORIDE IN PLASTIC CONTAINER vs NESACAINE-MPF
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Blocks voltage-gated sodium channels, inhibiting action potential propagation in neurons and cardiac myocytes.
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.
1-1.5 mg/kg IV bolus, then 0.5-0.75 mg/kg IV bolus every 5-10 min to a max of 3 mg/kg total loading dose; maintenance infusion 1-4 mg/min IV. For epidural: 5-10 mL of 1-2% solution.
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.

Terminal elimination half-life: 1.5–2 hours (single dose); prolonged to 2–3 hours with repeated dosing or in heart failure, liver disease, or elderly. Context: Effective for 1–2 hours after IV bolus, requiring infusion for sustained effect.
Terminal half-life: 3-4 hours (adults); prolonged in hepatic or renal impairment.
Renal excretion of unchanged drug and metabolites: ~90% as metabolites (e.g., monoethylglycinexylidide, glycinexylidide), <10% unchanged. Biliary/fecal: minimal (<1%).
Renal excretion of metabolites; <10% unchanged drug. Biliary/fecal elimination minor.
