ALPHACAINE HYDROCHLORIDE vs MEPIVACAINE HYDROCHLORIDE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Local anesthetic that reversibly blocks sodium ion channels in neuronal membranes, preventing the generation and propagation of action potentials.
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.
1–2% solution via local infiltration or nerve block, up to a maximum of 4.5 mg/kg (or 300 mg) without epinephrine; with epinephrine, maximum 7 mg/kg (or 500 mg).
1-2% solution, 5-20 mL local infiltration or nerve block, maximum 400 mg per procedure.

Terminal half-life 2.5-3.5 hours in adults; prolonged to 4-6 hours in hepatic impairment or elderly.
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.
Primarily renal excretion of unchanged drug and metabolites (70-80%); minor biliary elimination (10-15%); fecal excretion <5%.
Primarily hepatic metabolism via amidase enzymes; ~95% excreted as metabolites in bile and feces, <5% unchanged in urine.
