Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Chlorhexidine gluconate disrupts bacterial cell membranes and precipitates cell contents, providing rapid bactericidal activity. Isopropyl alcohol denatures proteins and disrupts cell membranes, enhancing antimicrobial effect.
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.
Topical antiseptic: apply to intact skin for 30 seconds and allow to dry for 30 seconds; single-use per patient.
Apply topically as a 3% emulsion to affected area, rinse thoroughly; typically used 1-2 times daily for up to 10 days.

Not applicable, as systemic absorption is negligible. For absorbed chlorhexidine, terminal half-life is approximately 1-2 hours due to rapid clearance, but this is clinically irrelevant.
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).
Chlorhexidine gluconate and isopropyl alcohol are not significantly absorbed systemically after topical application. For the minimal absorbed fraction, chlorhexidine is primarily excreted unchanged in feces via biliary elimination (~90%), with renal excretion accounting for <1%. Isopropyl alcohol is metabolized to acetone and excreted via lungs and urine; however, systemic absorption is negligible with intact skin.
Renal (biliary/fecal negligible). Up to 10% of dose excreted unchanged in urine; remainder as metabolites (glucuronide and sulfate conjugates).
