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.
Procaine, an ester-type local anesthetic, reversibly binds to the intracellular portion of voltage-gated sodium channels, inhibiting sodium influx and blocking nerve impulse conduction.
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.
Local infiltration: 0.5% solution, up to 20 mL (100 mg) per dose; nerve block: 1-2% solution, 5-10 mL (50-200 mg); maximum single dose: 7 mg/kg or 350 mg (without epinephrine).

Terminal elimination half-life is approximately 7–9 hours; clinically, steady-state is achieved after 2–3 days of daily application.
Plasma half-life: approximately 30–60 seconds due to rapid hydrolysis by pseudocholinesterases; clinical effects short-lived.
Approximately 60% of the dose is excreted renally as unchanged drug and metabolites; the remainder is eliminated via biliary/fecal routes.
Renal excretion of para-aminobenzoic acid (PABA) and diethylaminoethanol as major metabolites; <2% excreted unchanged in urine. Biliary/fecal: minimal.
