CITANEST PLAIN vs GLYDO
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Blocks sodium channels, inhibiting nerve impulse conduction.
GLYDO (lidocaine) is an amide-type local anesthetic that stabilizes the neuronal membrane by inhibiting sodium ion channels, thereby blocking the initiation and conduction of nerve impulses.
Prilocaine 1-2% solution: local infiltration, 1-20 mL of 1-2% (10-400 mg); nerve block, 10-40 mL of 1-2% (100-800 mg); epidural, 15-30 mL of 2% (300-600 mg). Maximum dose: 8 mg/kg (600 mg) as single dose, not to exceed 600 mg without epinephrine.
For anesthesia: 1-5% solution, 0.5-5 mg/kg IV or 2.5-15 mg intrathecally; for antiarrhythmic: 1-1.5 mg/kg IV bolus then 1-4 mg/min infusion.

The terminal elimination half-life of prilocaine is approximately 1.5 hours in adults with normal hepatic and renal function. In neonates, the half-life may be prolonged to 3-4 hours due to immature hepatic metabolism. This short half-life supports its use for procedures requiring moderate duration of anesthesia.
Terminal elimination half-life is approximately 1.5 to 2 hours in adults with normal hepatic and renal function. In neonates, half-life is prolonged (up to 3-4 hours) due to immature hepatic metabolism.
Prilocaine is metabolized primarily in the liver via amidases, with major metabolites including o-toluidine and N-propylalanine. Approximately 50-70% of the dose is excreted renally as metabolites, with less than 2% excreted unchanged in urine. Biliary/fecal excretion is minimal (<5%).
Renal excretion of unchanged drug accounts for approximately 10% of the dose; the remainder is metabolized in the liver to inactive metabolites that are excreted renally. Fecal elimination is negligible (<2%).
