AVAGARD vs CHLORHEXIDINE GLUCONATE
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.
Cationic bisbiguanide that disrupts microbial cell membranes by binding to negatively charged cell wall components, increasing permeability and causing leakage of cytoplasmic contents; also inhibits bacterial enzymes and precipitates cytoplasmic constituents.
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.
Oral rinse: 15 mL of 0.12% solution swished in mouth for 30 seconds twice daily; topical: apply 2% cream or lotion to affected area 2-3 times daily.

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 half-life approximately 12-24 hours; may be prolonged in hepatic impairment.
Primarily renal (unchanged drug and metabolites) with approximately 20-30% excreted fecally; renal clearance accounts for >60% of total clearance.
Primarily renal (10-30% unchanged) and biliary/fecal (majority as metabolites).
