MEPIVACAINE HYDROCHLORIDE vs SEPTOCAINE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Articaine is a local anesthetic of the amide type that stabilizes the neuronal membrane by inhibiting sodium ion influx, thereby blocking nerve impulse conduction.
1-2% solution, 5-20 mL local infiltration or nerve block, maximum 400 mg per procedure.
SEPTOCAINE (articaine HCl 4% with epinephrine 1:100,000 or 1:200,000) dental infiltration or nerve block: 0.5–1.7 mL (20–68 mg articaine) per injection site; maximum adult dose: 7 mg/kg (up to 500 mg total).

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.
Terminal elimination half-life in adults is 2-4 hours. In neonates, it may be prolonged to 8-12 hours due to immature hepatic function.
Primarily hepatic metabolism via amidase enzymes; ~95% excreted as metabolites in bile and feces, <5% unchanged in urine.
Primarily hepatic metabolism; less than 10% excreted unchanged in urine. Biliary/fecal elimination is negligible.
