BUPIVACAINE HYDROCHLORIDE PRESERVATIVE FREE vs SCANDONEST L
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Bupivacaine blocks voltage-gated sodium channels on neuronal membranes, inhibiting the propagation of action potentials and resulting in local anesthesia.
Scandonest L (mepivacaine hydrochloride) is an amide-type local anesthetic that stabilizes neuronal membranes by inhibiting sodium ion influx across the membrane, thereby blocking nerve impulse initiation and conduction.
0.25-0.5% solution, up to 2 mg/kg (max 150 mg) per dose via infiltration, peripheral nerve block, or epidural; may repeat every 3-6 hours as needed. For epidural: 0.5% solution, 15-20 mL for surgical anesthesia.
Dental infiltration or nerve block: 1.3 mL of 3% solution (isocaine) per site; maximum 9 mg/kg (0.3 mL/kg) per session. Infiltration: 0.5-1.0 mL; nerve block: 1.0-1.3 mL.

Terminal elimination half-life is 2.7 hours (range 1.5-5.5 hours). Prolonged up to 8-10 hours in neonates and 24-48 hours in severe hepatic impairment.
Terminal elimination half-life is 1.5–2.0 hours in healthy adults; prolonged to 3–5 hours in patients with hepatic impairment or severe renal disease.
Renal excretion accounts for approximately 95% of the dose, with about 50% excreted unchanged. The remainder is primarily hepatic metabolism followed by renal elimination of metabolites. Biliary/fecal excretion is minimal (<5%).
Primarily hepatic metabolism (approx. 90%) via amidase hydrolysis and aromatic hydroxylation; renal excretion of unchanged drug accounts for <5% of the dose; less than 1% excreted in feces.
