DENTIPATCH vs PROCAINE HYDROCHLORIDE
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.
Blocks voltage-gated sodium channels, inhibiting nerve impulse conduction by stabilizing the neuronal membrane and preventing depolarization.
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 200 mg (40 mL) per dose. Nerve block: 0.5% solution, 100-200 mg (20-40 mL) per dose. Intravenous regional anesthesia (Bier block): 0.5% solution, 50-100 mg (10-20 mL) per dose. Maximum total dose: 200 mg without epinephrine, 250 mg with epinephrine 1:200,000.

Terminal elimination half-life is approximately 7–9 hours; clinically, steady-state is achieved after 2–3 days of daily application.
Terminal elimination half-life is approximately 7.7 minutes in adults with normal hepatic function. This short half-life reflects rapid hydrolysis by plasma pseudocholinesterases. In patients with pseudocholinesterase deficiency, half-life may be prolonged to 20-30 minutes.
Approximately 60% of the dose is excreted renally as unchanged drug and metabolites; the remainder is eliminated via biliary/fecal routes.
Primarily renal excretion of metabolites (para-aminobenzoic acid and diethylaminoethanol) and unchanged drug. Approximately 80% of a dose is excreted in urine as para-aminobenzoic acid and conjugates; <2% excreted unchanged. Biliary/fecal elimination is negligible.
