AVAGARD vs CHG 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.
Chlorhexidine gluconate disrupts bacterial cell membranes, leading to leakage of intracellular contents and cell death. It also binds to proteins and inhibits bacterial enzymes.
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 5 mL to wet skin, scrub for 2 minutes, rinse thoroughly. Use undiluted.

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 2 hours (terminal); prolonged in renal impairment.
Primarily renal (unchanged drug and metabolites) with approximately 20-30% excreted fecally; renal clearance accounts for >60% of total clearance.
Primarily renal (90% unchanged); <5% biliary/fecal.
