Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Local anesthetic agent that inhibits sodium ion influx into nerve cells, blocking nerve conduction and pain sensation.
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.
Apply one 10 mg/10 cm² transdermal patch to intact skin once daily, typically in the morning; remove after 24 hours and replace with a new patch.
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.

Terminal elimination half-life is approximately 7–9 hours; clinically, steady-state is achieved after 2–3 days of daily application.
Lidocaine: 1.5-2 hours; prilocaine: 1.5-2 hours. In hepatic impairment, half-life may be prolonged up to 2-3 times.
Approximately 60% of the dose is excreted renally as unchanged drug and metabolites; the remainder is eliminated via biliary/fecal routes.
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.
