LIDOCAINE HYDROCHLORIDE 0.1% AND DEXTROSE 5% IN PLASTIC CONTAINER vs NESACAINE-MPF
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Lidocaine is a sodium channel blocker, which stabilizes neuronal membranes and inhibits the initiation and conduction of nerve impulses. Dextrose 5% provides caloric support.
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.
Intravenous: 50-100 mg bolus (1-2 mg/kg) over 2-3 minutes, followed by continuous infusion at 1-4 mg/min (20-50 mcg/kg/min). Total maximum dose: 300 mg over 1 hour.
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: 1.5–2.0 hours in adults with normal hepatic function. In patients with hepatic impairment or heart failure, half-life may be prolonged (>3 hours). Clinical context: short half-life requires continuous infusion for sustained antiarrhythmic effect.
Terminal half-life: 3-4 hours (adults); prolonged in hepatic or renal impairment.
Renal: approximately 10% unchanged; hepatic metabolism to 4-hydroxy-2,6-xylidine and glycylxylidide, which are excreted renally. Total renal excretion of metabolites and parent drug accounts for >95% of the dose. Fecal excretion is minimal (<5%).
Renal excretion of metabolites; <10% unchanged drug. Biliary/fecal elimination minor.
