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.
Lidocaine is an amide-type local anesthetic that stabilizes neuronal membranes by blocking voltage-gated sodium channels, thereby inhibiting the initiation and conduction of nerve impulses. It exhibits antiarrhythmic activity by suppressing automaticity and conduction in cardiac tissues.
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.
Antiarrhythmic: 1-1.5 mg/kg IV bolus, may repeat 0.5-0.75 mg/kg in 5-10 minutes; maximum total 3 mg/kg. Followed by continuous IV infusion 1-4 mg/min. Local anesthesia: maximum 4.5 mg/kg (300 mg) without epinephrine; 7 mg/kg (500 mg) with epinephrine.

Terminal elimination half-life is 1.5–2 hours (mean 1.8 h), necessitating frequent dosing for sustained effect.
Terminal elimination half-life: 1.5–2 hours (normal cardiac output and hepatic function). Prolonged in heart failure (up to 10 hours), hepatic disease (up to 5–15 hours), and with continuous infusion (due to saturable metabolism).
Renal excretion of unchanged drug accounts for approximately 70% of elimination, with 30% undergoing hepatic metabolism and biliary/fecal elimination.
Renal: ~90% as metabolites (including monoethylglycinexylidide [MEGX] and glycinexylidide [GX]) and ~10% unchanged. Biliary/fecal: <3%.
