ANOQUAN vs PARACAINE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Local anesthetic that reversibly blocks sodium channels in neuronal membranes, inhibiting nerve impulse conduction.

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).
Clinical Note
moderateProparacaine + Fluticasone propionate
"The risk or severity of adverse effects can be increased when Proparacaine is combined with Fluticasone propionate."
Clinical Note
moderateProparacaine + Clemastine
"The risk or severity of adverse effects can be increased when Proparacaine is combined with Clemastine."
Clinical Note
moderateProparacaine + Venlafaxine
"The risk or severity of adverse effects can be increased when Proparacaine is combined with Venlafaxine."
Clinical Note
moderate2.5 hours; prolonged to 8 hours in cirrhosis due to reduced hepatic metabolism
Renal excretion accounts for approximately 70% of the dose (50% as unchanged drug, 20% as inactive metabolites); biliary/fecal excretion accounts for 30%.
Renal: 90% (70% unchanged, 20% as paracainol glucuronide); Biliary/Fecal: 10%
