CARBOCAINE vs MEPIVACAINE HYDROCHLORIDE
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.
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.
1% to 2% solution, 5-20 mL local infiltration or nerve block; maximum dose 400 mg (or 7 mg/kg) per 90-minute period.

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 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 excretion of unchanged drug and metabolites accounts for approximately 95% of elimination, with less than 5% excreted in feces via biliary elimination.
Primarily hepatic metabolism via amidase enzymes; ~95% excreted as metabolites in bile and feces, <5% unchanged in urine.
