LIDOPEN vs MEPIVACAINE HYDROCHLORIDE
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.
Mepivacaine hydrochloride is an amide-type local anesthetic that reversibly blocks nerve impulse propagation by binding to sodium channels in the neuronal cell membrane, thereby stabilizing the membrane and preventing depolarization.
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.
1-2% solution, 5-20 mL local infiltration or nerve block, maximum 400 mg per procedure.

1.5–2 hours (terminal); prolonged in hepatic impairment
Terminal elimination half-life approximately 2 hours (range 1.5–3 hours). In neonates and patients with hepatic dysfunction, half-life may be prolonged up to 8–10 hours.
Renal (10% unchanged; 80% as metabolites), biliary/fecal (10%)
Primarily hepatic metabolism via amidase enzymes; ~95% excreted as metabolites in bile and feces, <5% unchanged in urine.
