Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Local anesthetic that stabilizes the neuronal membrane by inhibiting sodium ion influx, thereby blocking nerve impulse transmission.
Guanabenz is a centrally acting alpha-2 adrenergic agonist that reduces sympathetic outflow from the brain, leading to decreased peripheral vascular resistance and lowered blood pressure.
1 to 2 drops of 0.5% solution topically to the eye, repeated as needed for anesthesia.

Terminal elimination half-life: 0.4–1.2 minutes (rapid enzymatic hydrolysis by plasma esterases); clinical significance: ultra-short duration limits systemic toxicity.
Terminal elimination half-life is 12-15 hours in adults with normal renal function; prolonged to 24-48 hours in severe renal impairment (CrCl <30 mL/min).
Renal excretion of parent drug and metabolites: <5% unchanged.
Renal excretion accounts for approximately 70% of the dose (50% as unchanged drug, 20% as inactive metabolites); biliary/fecal excretion accounts for 30%.
