Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Lidocaine, the active ingredient, inhibits voltage-gated sodium channels, blocking the initiation and conduction of nerve impulses, leading to local anesthesia.
Local anesthetic that blocks voltage-gated sodium channels in neuronal membranes, preventing propagation of action potentials and transmission of pain signals.
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.
Dental infiltration or nerve block: 1-2 cartridges (36-72 mg mepivacaine; 0.009-0.018 mg levonordefrin) of 2% solution with 1:20,000 levonordefrin; maximum dose: 4.4 mg/kg mepivacaine (not to exceed 300 mg) per appointment.

Terminal elimination half-life is approximately 1.5–2 hours in adults. Prolonged in hepatic impairment or heart failure.
Terminal elimination half-life is approximately 2-3 hours in adults. In neonates, half-life is prolonged (8-10 hours due to immature hepatic function). Clinical context: Short half-life reduces risk of systemic accumulation with repeated doses.
Primarily hepatic metabolism; <10% excreted unchanged in urine. Biliary/fecal excretion is minimal.
Mepivacaine is primarily metabolized in the liver via N-demethylation and hydroxylation. Less than 5% is excreted unchanged in urine. Hepatic clearance accounts for >90% of elimination; renal excretion of metabolites accounts for the remainder. Fecal elimination is minimal (<2%).
