LIDOCAINE AND PRILOCAINE vs SCANDONEST L
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Lidocaine and prilocaine are amide-type local anesthetics that stabilize neuronal membranes by inhibiting sodium ion channels, thereby blocking the initiation 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.
Apply 2.5 g cream (lidocaine 25 mg/prilocaine 25 mg) to intact skin under occlusive dressing; maximum single application area 400 cm², maximum application time 4 hours. For genital mucous membranes: apply 5-10 g for 5-10 minutes without occlusion. Not recommended for dental use.
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.

Lidocaine: 1.5-2 hours; prilocaine: 1.5-2 hours. In hepatic impairment, half-life may be prolonged up to 2-3 times.
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 metabolites (lidocaine: 70-80% as 4-hydroxy-2,6-xylidine and conjugates; prilocaine: 85-95% as o-toluidine metabolites and conjugates). Less than 10% of parent drugs excreted unchanged.
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.
