Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Blocks voltage-gated sodium channels, inhibiting nerve impulse conduction by stabilizing the neuronal membrane and preventing depolarization.
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.
Local infiltration: 0.5% solution, up to 200 mg (40 mL) per dose. Nerve block: 0.5% solution, 100-200 mg (20-40 mL) per dose. Intravenous regional anesthesia (Bier block): 0.5% solution, 50-100 mg (10-20 mL) per dose. Maximum total dose: 200 mg without epinephrine, 250 mg with epinephrine 1:200,000.
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 elimination half-life is approximately 7.7 minutes in adults with normal hepatic function. This short half-life reflects rapid hydrolysis by plasma pseudocholinesterases. In patients with pseudocholinesterase deficiency, half-life may be prolonged to 20-30 minutes.
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 metabolites (para-aminobenzoic acid and diethylaminoethanol) and unchanged drug. Approximately 80% of a dose is excreted in urine as para-aminobenzoic acid and conjugates; <2% excreted unchanged. Biliary/fecal elimination is negligible.
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%).
