SCANDONEST L vs SENSORCAINE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
SENSORCAINE (bupivacaine) is an amide-type local anesthetic that blocks sodium ion channels in nerve cell membranes, thereby inhibiting depolarization and propagation of action potentials, resulting in reversible local 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.
Epidural or caudal block: 15-30 mL of 0.5% to 1% solution (75-150 mg) every 2-4 hours as needed. Maximum single dose: 225 mg.

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.
The terminal elimination half-life of bupivacaine is approximately 2.7 hours in adults (range 1.5–5.5 hours). In neonates, the half-life is significantly prolonged (~8–12 hours) due to immature hepatic function, leading to an increased risk of toxicity.
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.
SENSORCAINE (bupivacaine) is primarily metabolized in the liver via conjugation with glucuronic acid and undergoes hepatic dealkylation. Approximately 6% of the drug is excreted unchanged in the urine. The majority of the dose (about 95%) is excreted as metabolites in the urine (<10% unchanged) and the remainder in feces via biliary elimination.
