MARCAINE HYDROCHLORIDE vs SCANDONEST L
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Bupivacaine is an amide-type local anesthetic that blocks voltage-gated sodium channels in nerve cell membranes, reversibly inhibiting nerve impulse propagation, particularly in sensory fibers.
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.
Adults: 0.5% solution infiltrated up to 175 mg (35 mL) for minor procedures; for major procedures, up to 225 mg (45 mL) with epinephrine. Repeat doses at 3-hour intervals. Maximum dose 400 mg with epinephrine.
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 approximately 2.5 to 3.5 hours in adults; may be prolonged in neonates (8-12 hours) or patients with 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.
Primarily hepatic metabolism; less than 5% excreted unchanged in urine. Metabolites are excreted renally, with a small amount in feces via biliary elimination.
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.
