SCANDONEST PLAIN vs VIVACAINE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
VIVACAINE is a local anesthetic that blocks the generation and conduction of nerve impulses by decreasing sodium ion permeability across the neuronal membrane.
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.
5-10 mL of 1% solution (50-100 mg) via submucosal infiltration or nerve block; maximum 500 mg per procedure.

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.
Terminal elimination half-life: 6–8 hours in healthy adults. In patients with hepatic impairment, half-life may be prolonged up to 12–15 hours; in severe renal impairment (CrCl <30 mL/min), half-life may extend to 10–12 hours.
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%).
Renal excretion of unchanged drug and metabolites accounts for approximately 85–90% of elimination, with about 10–15% excreted in feces via biliary clearance. Less than 2% of the dose is recovered unchanged in urine; the remainder is as glucuronide conjugates and other metabolites.
