ARESTOCAINE HYDROCHLORIDE vs MEPIVACAINE HYDROCHLORIDE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Arestocaine hydrochloride is a local anesthetic of the amide type. It stabilizes the neuronal membrane by inhibiting the ionic fluxes required for the initiation and conduction of impulses, thereby effecting 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.
2-5 mg/kg intramuscularly every 60-90 minutes, not to exceed 500 mg total dose in a 12-hour period.
1-2% solution, 5-20 mL local infiltration or nerve block, maximum 400 mg per procedure.

Terminal elimination half-life is approximately 1.5–2 hours in adults with normal hepatic and renal function; prolonged in hepatic impairment or congestive heart failure.
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; approximately 90% excreted in urine as parent compound and metabolites (60% as unchanged drug, 30% as metabolites), with less than 10% fecal elimination.
Primarily hepatic metabolism via amidase enzymes; ~95% excreted as metabolites in bile and feces, <5% unchanged in urine.
