CHLORAPREP WITH TINT vs PHISOHEX
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Disrupts bacterial cell wall synthesis by binding to the bacterial ribosome and inhibiting protein synthesis; also has surfactant properties that disrupt bacterial cell membrane integrity.
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.
Apply topically as a 3% emulsion to affected area, rinse thoroughly; typically used 1-2 times daily for up to 10 days.

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.
Terminal elimination half-life approximately 6-7 hours in adults with normal renal function. Prolonged in renal impairment (up to 20 hours) due to reduced clearance of active metabolite (pentachlorophenol).
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.
Renal (biliary/fecal negligible). Up to 10% of dose excreted unchanged in urine; remainder as metabolites (glucuronide and sulfate conjugates).
