AVAGARD vs ORAQIX
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Avagard (chlorhexidine gluconate 1% and isopropyl alcohol 61%) is an antiseptic with bactericidal activity. Chlorhexidine disrupts cell membranes and precipitates cell contents; isopropyl alcohol denatures proteins and dissolves lipids.
Oraqix is a eutectic mixture of lidocaine and prilocaine that acts as a local anesthetic. It reversibly blocks sodium ion channels in nerve cell membranes, inhibiting the initiation and conduction of nerve impulses, thereby producing anesthesia.
Chlorhexidine gluconate 2% + isopropyl alcohol 70% solution: apply 5 mL to each hand and forearm, rub vigorously for 2-3 minutes, allow to dry; repeat once. For surgical hand antisepsis: apply 5 mL to hands and forearms, scrub for 3 minutes, rinse, repeat.
750 mg orally once daily for 5 days; or 250 mg orally once daily for 5 days (levofloxacin equivalent).

Terminal elimination half-life is 4-6 hours in patients with normal renal function; prolonged to 18-24 hours in severe renal impairment (CrCl <30 mL/min).
Terminal elimination half-life: 7.5 hours (range 6-9 h) in patients with normal renal function; extends to 20-30 h in severe renal impairment (CrCl <30 mL/min), necessitating dose adjustment.
Primarily renal (unchanged drug and metabolites) with approximately 20-30% excreted fecally; renal clearance accounts for >60% of total clearance.
Renal: ~60% unchanged; biliary/fecal: ~30% as metabolites and parent drug; total clearance approximates renal clearance.
