Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Local anesthetic that reversibly blocks sodium ion channels in neuronal membranes, preventing the generation and propagation of action potentials.
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.
1–2% solution via local infiltration or nerve block, up to a maximum of 4.5 mg/kg (or 300 mg) without epinephrine; with epinephrine, maximum 7 mg/kg (or 500 mg).
100 mg orally twice daily

Terminal half-life 2.5-3.5 hours in adults; prolonged to 4-6 hours in hepatic impairment or elderly.
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).
Primarily renal excretion of unchanged drug and metabolites (70-80%); minor biliary elimination (10-15%); fecal excretion <5%.
Renal excretion accounts for approximately 70% of the dose (50% as unchanged drug, 20% as inactive metabolites); biliary/fecal excretion accounts for 30%.
