POLOCAINE-MPF vs SEPTOCAINE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Polocaine-MPF (mepivacaine hydrochloride) is an amide-type local anesthetic that blocks sodium ion channels in nerve cell membranes, thereby preventing the initiation and propagation of nerve impulses. This results in reversible loss of sensation in the area of administration.
Articaine is a local anesthetic of the amide type that stabilizes the neuronal membrane by inhibiting sodium ion influx, thereby blocking nerve impulse conduction.
Adults: 1-2 cartridges (1.8 mL each) of 2% lidocaine with 1:100,000 epinephrine administered via local infiltration or nerve block, not to exceed 7 mg/kg (maximum 500 mg) for lidocaine.
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: 1.5-2.0 hours in adults; prolonged in hepatic impairment (up to 4-6 hours) and severe renal impairment. Clinical context: short half-life supports continuous infusion for sustained effect.
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.
Renal: >90% as metabolites, primarily 4-hydroxy-2',6'-dimethylacetanilide and pipecoloxylidide; unchanged drug <5%. Biliary/fecal: <5%.
Primarily hepatic metabolism; less than 10% excreted unchanged in urine. Biliary/fecal elimination is negligible.
