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 and tetracaine are sodium channel blockers, inhibiting nerve impulse conduction, providing local anesthesia. Epinephrine is a vasoconstrictor that reduces systemic absorption and prolongs duration.
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.
4 mL of 4% lidocaine (160 mg) via atomizer or nebulizer for topical laryngotracheal anesthesia, with additional 2 mL aliquots as needed, not to exceed 4.5 mg/kg total dose.

Terminal elimination half-life is 1.5–2 hours (mean 1.8 h), necessitating frequent dosing for sustained effect.
Lidocaine terminal half-life: 1.5–2 hours (normal hepatic function); prolonged to 3–5 hours in heart failure or hepatic disease. Tetracaine: 2–3 hours.
Renal excretion of unchanged drug accounts for approximately 70% of elimination, with 30% undergoing hepatic metabolism and biliary/fecal elimination.
Renal excretion of lidocaine and its metabolites (primarily monoethylglycinexylidide (MEGX) and glycinexylidide (GX)); <10% unchanged. Biliary/fecal excretion minimal (<5%).
