DURANEST vs NESACAINE-MPF
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Etonidate is an ultrashort-acting nonbarbiturate hypnotic agent that produces anesthesia by enhancing GABA-mediated chloride conductance at GABA-A receptors, leading to central nervous system depression.
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.
2-10 mL of a 1-2% solution, subarachnoid injection, single dose only.
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 is 4.5 hours (range 3-6 hours). Clinical context: Prolonged in severe hepatic impairment but not significantly in renal impairment.
Terminal half-life: 3-4 hours (adults); prolonged in hepatic or renal impairment.
Primarily hepatic metabolism; renal excretion of metabolites accounts for <10% unchanged drug. Biliary/fecal elimination is minimal.
