ANOQUAN vs LIDOCAINE VISCOUS
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.
Lidocaine is an amide-type local anesthetic that blocks voltage-gated sodium channels (Nav1.7, Nav1.8) in neuronal membranes, inhibiting depolarization and propagation of action potentials, thereby producing local anesthesia. It also has antiarrhythmic properties (class IB) by blocking sodium channels in cardiac myocytes.

15 mL (300 mg) orally every 3 hours as needed for pain; maximum 8 doses per 24 hours.

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).
Terminal elimination half-life is 1.5–2 hours (up to 3 hours in hepatic impairment). Clinically, redistribution half-life (~6 min) determines duration of action after short infusions.
Renal excretion accounts for approximately 70% of the dose (50% as unchanged drug, 20% as inactive metabolites); biliary/fecal excretion accounts for 30%.
Renal excretion of unchanged drug and metabolites accounts for >90% of elimination; <10% biliary/fecal. Metabolites include monoethylglycinexylidide (MEGX) and glycinexylidide (GX).
