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 that stabilizes neuronal membranes by inhibiting the ionic fluxes required for initiation and conduction of impulses, thereby producing local anesthesia. Dextrose 5% provides caloric support.
1% to 2% solution, 5-20 mL local infiltration or nerve block; maximum dose 400 mg (or 7 mg/kg) per 90-minute period.
Intravenous administration: Initial dose of 1-1.5 mg/kg (up to 300 mg total) given at a rate not exceeding 50 mg/min. Followed by continuous infusion at 1-4 mg/min (20-50 mcg/kg/min) for arrhythmia management.

2.0–3.5 hours in adults; prolonged in patients with hepatic impairment (up to 8–10 hours) or renal dysfunction.
Terminal elimination half-life: 1.5–2 hours (prolonged to 2–3 hours in hepatic impairment; unchanged in renal 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 excretion of unchanged drug and metabolites: 10% unchanged, 90% as metabolites (primarily 4-hydroxy-2,6-xylidine and glycylxylidide). Less than 1% biliary/fecal.
