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.
Prilocaine hydrochloride is an amino amide local anesthetic that reversibly blocks sodium channels in nerve cell membranes, inhibiting nerve impulse propagation.
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.
Adults: 4 mg/kg (max 200 mg) via infiltration or nerve block; may repeat after 2 hours with 50% of initial dose.

Terminal elimination half-life is approximately 7–9 hours; clinically, steady-state is achieved after 2–3 days of daily application.
Terminal half-life: 1.5-2 hours (adults, normal hepatic function). Prolonged in neonates (up to 8-12 hours) due to immature hepatic metabolism and reduced clearance; may cause methemoglobinemia. Hepatic impairment increases half-life.
Approximately 60% of the dose is excreted renally as unchanged drug and metabolites; the remainder is eliminated via biliary/fecal routes.
Renal: ~95% as metabolites (primarily o-toluidine and 4-hydroxy-2-methylaniline) and <5% unchanged. Biliary/fecal: minimal (<2%).
