ALPHACAINE vs SCANDONEST L
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
ALPHACAINE is a local anesthetic that binds to the intracellular portion of voltage-gated sodium channels, blocking sodium influx and preventing depolarization and conduction of nerve impulses.
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.
10-20 mg IM or IV every 4-6 hours as needed; maximum 80 mg/day.
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: 3.5-5.0 hours (prolonged in hepatic impairment; requires dose adjustment in Child-Pugh B or C).
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: ~60-70% unchanged; Hepatic metabolism: ~20-30% via CYP3A4 and CYP2C9; Fecal: <10%.
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.
