CHIROCAINE vs SCANDONEST PLAIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Chirocaine (levobupivacaine) is a long-acting local anesthetic of the amide type. It blocks sodium channels, inhibiting nerve impulse initiation and conduction, thereby producing local anesthesia.
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.
0.5% to 0.75% solution; epidural: 10-20 mL of 0.5% solution (50-100 mg) as initial dose; for surgical anesthesia, 15-20 mL of 0.75% solution (112.5-150 mg); repeat doses of 0.25% to 0.5% solution at 40-60 minute intervals as needed. Maximum single dose: 225 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 elimination half-life is 0.5–1.5 hours (adults) and 1–2 hours (neonates). Clinically, this short half-life limits accumulation with repeated doses.
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.
Renal excretion accounts for approximately 95% of the dose, with most being eliminated as metabolites (mainly p-aminobenzoic acid and other conjugates) and less than 5% as unchanged drug. Biliary/fecal excretion is minimal (<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%).
