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, a local anesthetic, stabilizes neuronal membranes by inhibiting sodium ion channels, blocking initiation and conduction of nerve impulses. Epinephrine causes vasoconstriction via alpha-1 adrenergic receptor activation, reducing systemic absorption of lidocaine and prolonging local effect.
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.
Topical administration via laryngeal spray: 1-2 sprays (10-20 mg) to the larynx and pharynx, repeated as needed up to every 1-2 hours, not to exceed 8 sprays per 24 hours.

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 1.5–2 hours (mean 1.8 h), necessitating frequent dosing for sustained effect.
Approximately 60% of the dose is excreted renally as unchanged drug and metabolites; the remainder is eliminated via biliary/fecal routes.
Renal excretion of unchanged drug accounts for approximately 70% of elimination, with 30% undergoing hepatic metabolism and biliary/fecal elimination.
