Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Lidocaine is a local anesthetic that stabilizes neuronal membranes by inhibiting sodium ion influx, thereby blocking initiation and conduction of nerve impulses.
Prilocaine hydrochloride is an amino amide local anesthetic that reversibly blocks sodium channels in nerve cell membranes, inhibiting nerve impulse propagation.
1-1.5 mg/kg IV bolus over 2-3 minutes, followed by continuous IV infusion of 1-4 mg/min for ventricular arrhythmias; maximum 3 mg/kg (or 200-300 mg) over 1 hour.
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: 1.5-2 hours (adults); prolonged in heart failure (up to 4-6 hours) or hepatic impairment (up to 5-7 hours).
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.
Renal: ~90% as metabolites and <10% unchanged. Biliary/fecal: minor (<1%).
Renal: ~95% as metabolites (primarily o-toluidine and 4-hydroxy-2-methylaniline) and <5% unchanged. Biliary/fecal: minimal (<2%).
