ARESTOCAINE HYDROCHLORIDE W/ LEVONORDEFRIN vs LIGNOSPAN STANDARD
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Articaine hydrochloride is a local anesthetic of the amide type that blocks voltage-gated sodium channels in nerve cell membranes, inhibiting the generation and conduction of nerve impulses. Levonordefrin is a sympathomimetic vasoconstrictor that acts on alpha-adrenergic receptors to produce local vasoconstriction, reducing absorption of the anesthetic and prolonging its effect.
Lidocaine, the active ingredient, inhibits voltage-gated sodium channels, blocking the initiation and conduction of nerve impulses, leading to local anesthesia.
For local anesthesia: 1-5 mL of 2% solution (20 mg/mL) with levonordefrin 1:20,000, infiltrated locally; maximum single dose: 3.5 mg/kg (not to exceed 200 mg total).
2% lidocaine with 1:100,000 epinephrine: 1-5 mL (20-100 mg lidocaine) locally infiltrated; max 7 mg/kg lidocaine (up to 500 mg) per procedure. For nerve block: 1-30 mL depending on site. Epinephrine max 0.2 mg (20 mL of 1:100,000 solution) in healthy adults.

Articaine: approximately 1-2 hours (terminal half-life). Levonordefrin: not separately reported; vasoconstrictor effect duration supports anesthetic action. Clinical context: half-life is short, reflecting rapid metabolism by plasma esterases; clinical duration of anesthesia is prolonged by levonordefrin.
Terminal elimination half-life is approximately 1.5–2 hours in adults. Prolonged in hepatic impairment or heart failure.
Renal: primarily as metabolites (hydroxy derivatives) and unchanged drug; approximately 90% eliminated in urine as metabolites, <5% unchanged. Biliary/fecal: minor, <10%.
Primarily hepatic metabolism; <10% excreted unchanged in urine. Biliary/fecal excretion is minimal.
