Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Iontocaine (lidocaine 2% and epinephrine 0.01%) combines a sodium channel blocker (lidocaine) to inhibit nerve impulse propagation, producing local anesthesia, with epinephrine causing vasoconstriction to reduce systemic absorption and prolong effect.
Lidocaine is a amide-type local anesthetic that blocks voltage-gated sodium channels in neuronal membranes, inhibiting the initiation and conduction of nerve impulses. Dextrose provides calories and does not have pharmacological activity.
IONTOCAINE is not a recognized drug. No standard dosing available.
Intravenous administration: 1-1.5 mg/kg bolus, followed by 1-4 mg/min continuous infusion for ventricular arrhythmias. Maximum total dose: 3 mg/kg bolus; infusion for up to 24 hours. Note: 0.4% concentration = 4 mg/mL, 5% dextrose as diluent.

Terminal elimination half-life is 2.5-3.0 hours; prolonged in renal impairment (up to 6-8 hours).
Terminal elimination half-life: 1.5–2 hours after a single dose in healthy adults. In patients with hepatic impairment, heart failure, or prolonged infusion, half-life can increase to >3 hours due to reduced clearance. Neonates: 3–6.3 hours.
Primarily renal excretion of unchanged drug (70-80%) and glucuronide conjugate (15-20%); less than 10% fecal.
Renal: Approximately 90% of lidocaine is metabolized in the liver, and less than 10% is excreted unchanged in urine. The major metabolites (monoethylglycinexylidide and glycinexylidide) are excreted renally. Biliary/fecal excretion is minimal (<1%).
