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 an amide-type local anesthetic that stabilizes the neuronal membrane by inhibiting sodium ion channels, thereby blocking the initiation and conduction of nerve impulses.
1% to 2% solution, 5-20 mL local infiltration or nerve block; maximum dose 400 mg (or 7 mg/kg) per 90-minute period.
Adult: 5-25 mL (250-1250 mg lidocaine) of 5% lidocaine with glucose 7.5% solution, administered by caudal or lumbar epidural injection, single dose. Max total dose: 1250 mg.

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 heart failure, hepatic disease, or elderly; neonates 3-6 hours due to immature hepatic function.
Renal excretion of unchanged drug and metabolites accounts for approximately 95% of elimination, with less than 5% excreted in feces via biliary elimination.
Hepatic metabolism (90% N-dealkylation by CYP1A2/CYP3A4 to monoethylglycinexylidide and glycinexylidide); renal excretion of metabolites and parent drug (<10% unchanged); <1% biliary/fecal.
