Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Arestocaine hydrochloride is a local anesthetic of the amide type. It stabilizes the neuronal membrane by inhibiting the ionic fluxes required for the initiation and conduction of impulses, thereby effecting local anesthesia.
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.
2-5 mg/kg intramuscularly every 60-90 minutes, not to exceed 500 mg total dose in a 12-hour period.
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 1.5–2 hours in adults with normal hepatic and renal function; prolonged in hepatic impairment or congestive heart failure.
Terminal elimination half-life is 1.5–2 hours (mean 1.8 h), necessitating frequent dosing for sustained effect.
Renal excretion of unchanged drug and metabolites; approximately 90% excreted in urine as parent compound and metabolites (60% as unchanged drug, 30% as metabolites), with less than 10% fecal elimination.
Renal excretion of unchanged drug accounts for approximately 70% of elimination, with 30% undergoing hepatic metabolism and biliary/fecal elimination.
