Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Chlorhexidine gluconate disrupts microbial cell membrane integrity and precipitates cytoplasmic contents, providing rapid bactericidal activity against a broad spectrum of gram-positive and gram-negative bacteria, as well as some fungi and viruses. Isopropyl alcohol denatures proteins and disrupts cell membranes, enhancing antimicrobial activity.

Apply chlorhexidine 2% and isopropyl alcohol 70% solution to the surgical site as a single preoperative skin preparation; no additional scrubbing or rubbing required.
Topical antiseptic: apply to intact skin for 30 seconds and allow to dry for 30 seconds; single-use per patient.

Chlorhexidine has a terminal elimination half-life of approximately 1-2 hours in plasma after intravenous administration in animal studies; however, after topical application, systemic levels are undetectable, making half-life clinically irrelevant.
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.
Chlorhexidine is primarily excreted unchanged in feces (>90%) after oral administration, with minimal renal excretion (<1%). After cutaneous application, negligible systemic absorption occurs, and any absorbed chlorhexidine is excreted renally as unchanged drug (<1% of dose).
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.
