AVAGARD vs READYPREP CHG
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 microbial cell membranes, causing leakage of cytoplasmic contents and cell death. Its cationic nature binds to negatively charged bacterial cell walls, providing persistent antimicrobial activity.
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.
No standard systemic dosing; used as a 4% chlorhexidine gluconate topical antiseptic solution applied once daily to entire body for preoperative skin preparation or for chlorhexidine bathing in infection prevention protocols.

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).
60 minutes (terminal) in patients with normal renal function; prolonged in renal impairment.
Primarily renal (unchanged drug and metabolites) with approximately 20-30% excreted fecally; renal clearance accounts for >60% of total clearance.
Renal: ~100% unchanged via glomerular filtration. No biliary or fecal elimination.
