Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Local anesthetic that stabilizes the neuronal membrane by inhibiting the influx of sodium ions, thereby blocking nerve impulse propagation.
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.
100 mg orally every 12 hours

Terminal elimination half-life is 1.5–2 hours (mean 1.8 h), necessitating frequent dosing for sustained effect.
Terminal elimination half-life approximately 1.5-2.0 hours in adults; prolonged to 3-5 hours in hepatic impairment and neonates.
Renal excretion of unchanged drug accounts for approximately 70% of elimination, with 30% undergoing hepatic metabolism and biliary/fecal elimination.
Hepatic metabolism to 2,6-xylidine and 4-hydroxy-2,6-xylidine; <10% excreted unchanged in urine; approximately 70-80% of metabolites excreted renally, with <5% in feces.
