Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Mepivacaine, the active ingredient in Carbocaine, is an amide-type local anesthetic that blocks sodium ion channels in nerve cell membranes, thereby inhibiting the initiation and conduction of nerve impulses.
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.
1% to 2% solution, 5-20 mL local infiltration or nerve block; maximum dose 400 mg (or 7 mg/kg) per 90-minute period.
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.

2.0–3.5 hours in adults; prolonged in patients with hepatic impairment (up to 8–10 hours) or renal dysfunction.
1.5–2 hours (terminal); prolonged in hepatic impairment
Renal excretion of unchanged drug and metabolites accounts for approximately 95% of elimination, with less than 5% excreted in feces via biliary elimination.
Renal (10% unchanged; 80% as metabolites), biliary/fecal (10%)
