LIDOCAINE VISCOUS vs SCANDONEST L
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Lidocaine is an amide-type local anesthetic that blocks voltage-gated sodium channels (Nav1.7, Nav1.8) in neuronal membranes, inhibiting depolarization and propagation of action potentials, thereby producing local anesthesia. It also has antiarrhythmic properties (class IB) by blocking sodium channels in cardiac myocytes.
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.
15 mL (300 mg) orally every 3 hours as needed for pain; maximum 8 doses per 24 hours.
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 1.5–2 hours (up to 3 hours in hepatic impairment). Clinically, redistribution half-life (~6 min) determines duration of action after short infusions.
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 of unchanged drug and metabolites accounts for >90% of elimination; <10% biliary/fecal. Metabolites include monoethylglycinexylidide (MEGX) and glycinexylidide (GX).
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.
