ALPHACAINE HYDROCHLORIDE vs SCANDONEST PLAIN
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.
Scandonest Plain (mepivacaine) is an amide-type local anesthetic that stabilizes neuronal membranes by binding to voltage-gated sodium channels, inhibiting sodium influx and blocking nerve impulse conduction.
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).
Dental infiltration: 1-2 mL (20-40 mg mepivacaine). Nerve block: 2-4 mL (40-80 mg). Max dose: 400 mg (approx 7 mg/kg). Do not repeat within 2 hours.

Terminal half-life 2.5-3.5 hours in adults; prolonged to 4-6 hours in hepatic impairment or elderly.
Terminal elimination half-life: 1.9–3.2 hours in healthy adults; prolonged to 6–8 hours in hepatic impairment or severe renal disease; clinically meaningful for redosing intervals.
Primarily renal excretion of unchanged drug and metabolites (70-80%); minor biliary elimination (10-15%); fecal excretion <5%.
Renal excretion of unchanged drug and metabolites accounts for >95% of elimination; approximately 80% as unchanged mepivacaine and 15% as N-demethylated metabolites; biliary/fecal excretion minimal (<5%).
