Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Chirocaine (levobupivacaine) is a long-acting local anesthetic of the amide type. It blocks sodium channels, inhibiting nerve impulse initiation and conduction, thereby producing 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.
0.5% to 0.75% solution; epidural: 10-20 mL of 0.5% solution (50-100 mg) as initial dose; for surgical anesthesia, 15-20 mL of 0.75% solution (112.5-150 mg); repeat doses of 0.25% to 0.5% solution at 40-60 minute intervals as needed. Maximum single dose: 225 mg.
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 0.5–1.5 hours (adults) and 1–2 hours (neonates). Clinically, this short half-life limits accumulation with repeated doses.
Terminal elimination half-life is 1.5–2 hours (mean 1.8 h), necessitating frequent dosing for sustained effect.
Renal excretion accounts for approximately 95% of the dose, with most being eliminated as metabolites (mainly p-aminobenzoic acid and other conjugates) and less than 5% as unchanged drug. Biliary/fecal excretion is minimal (<5%).
Renal excretion of unchanged drug accounts for approximately 70% of elimination, with 30% undergoing hepatic metabolism and biliary/fecal elimination.
