AVAGARD vs PHISOHEX
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.
Disrupts bacterial cell wall synthesis by binding to the bacterial ribosome and inhibiting protein synthesis; also has surfactant properties that disrupt bacterial cell membrane integrity.
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.
Apply topically as a 3% emulsion to affected area, rinse thoroughly; typically used 1-2 times daily for up to 10 days.

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 approximately 6-7 hours in adults with normal renal function. Prolonged in renal impairment (up to 20 hours) due to reduced clearance of active metabolite (pentachlorophenol).
Primarily renal (unchanged drug and metabolites) with approximately 20-30% excreted fecally; renal clearance accounts for >60% of total clearance.
Renal (biliary/fecal negligible). Up to 10% of dose excreted unchanged in urine; remainder as metabolites (glucuronide and sulfate conjugates).
