LIDOPEN vs SEPTOCAINE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Lidocaine is a sodium channel blocker, stabilizing neuronal membranes by inhibiting the influx of sodium ions, thereby preventing the propagation of action potentials and producing local anesthesia.
Articaine is a local anesthetic of the amide type that stabilizes the neuronal membrane by inhibiting sodium ion influx, thereby blocking nerve impulse conduction.
Lidocaine 2% topical gel: Apply 1-2 grams (approximately 5-10 cm ribbon) to affected area every 4-6 hours as needed, not to exceed 5 grams per day. For infiltration anesthesia: 1% solution, 0.5-5 mL injected locally; maximum 4.5 mg/kg.
SEPTOCAINE (articaine HCl 4% with epinephrine 1:100,000 or 1:200,000) dental infiltration or nerve block: 0.5–1.7 mL (20–68 mg articaine) per injection site; maximum adult dose: 7 mg/kg (up to 500 mg total).

1.5–2 hours (terminal); prolonged in hepatic impairment
Terminal elimination half-life in adults is 2-4 hours. In neonates, it may be prolonged to 8-12 hours due to immature hepatic function.
Renal (10% unchanged; 80% as metabolites), biliary/fecal (10%)
Primarily hepatic metabolism; less than 10% excreted unchanged in urine. Biliary/fecal elimination is negligible.
