AVAGARD vs PHISO-SCRUB
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.
Phiso-Scrub is a topical antiseptic containing triclosan, which inhibits bacterial fatty acid synthesis by targeting enoyl-acyl carrier protein reductase (FabI), leading to disruption of cell membrane integrity and bacterial cell death.
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.
Topical application to affected area once daily; chlorhexidine gluconate 4% scrub, lather for 3-5 minutes, rinse thoroughly.

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).
Approximately 8-12 hours in patients with normal renal function (CrCl >90 mL/min). Half-life is significantly prolonged in renal impairment (up to 40 hours in ESRD).
Primarily renal (unchanged drug and metabolites) with approximately 20-30% excreted fecally; renal clearance accounts for >60% of total clearance.
Primarily renal excretion of unchanged drug (approximately 70-80% of absorbed dose). Biliary/fecal elimination accounts for the remainder (20-30%).
