AVAGARD vs CHLORAPREP WITH TINT
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 and precipitates cytoplasmic contents, providing rapid bactericidal activity against gram-positive and gram-negative bacteria. Isopropyl alcohol denatures proteins and disrupts cell membranes, enhancing 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.
Apply topically to intact skin as a single-use applicator; allow to dry for at least 3 minutes or until dry; do not use on open wounds or mucous membranes.

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).
Chlorhexidine is rapidly eliminated from plasma after IV administration with a terminal half-life of 2-5 hours due to extensive tissue distribution; for topical use, half-life is not clinically relevant as drug acts locally without significant systemic levels.
Primarily renal (unchanged drug and metabolites) with approximately 20-30% excreted fecally; renal clearance accounts for >60% of total clearance.
CHLORAPREP WITH TINT (2% chlorhexidine gluconate and 70% isopropyl alcohol) is a topical antiseptic; systemic absorption is negligible. Renal excretion of absorbed chlorhexidine is minimal (<1% of dose). Biliary/fecal elimination accounts for ~90% of absorbed dose as unchanged drug or metabolites. >90% of topical dose remains on skin.
