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.
Chlorhexidine gluconate and isopropyl alcohol act as antiseptics. Chlorhexidine disrupts bacterial cell membranes and precipitates cytoplasmic contents, while isopropyl alcohol denatures proteins and dissolves lipids, leading to rapid microbial death.
Apply chlorhexidine 2% and isopropyl alcohol 70% solution to the surgical site as a single preoperative skin preparation; no additional scrubbing or rubbing required.
Apply topically to intact skin for 30 seconds and allow to dry for at least 3 minutes. Dosage is based on area of skin to be disinfected; typically one swabstick per site.

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.
Chlorhexidine gluconate: Terminal elimination half-life is approximately 1.1 hours for the absorbed fraction in plasma after topical application; however, the drug persists at the application site with substantive activity for up to 6 hours. Alcohol evaporates rapidly; half-life of isopropyl alcohol in blood is <1 hour.
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 is primarily excreted unchanged in feces (≥90%) after oral administration; negligible renal excretion (<1%). Isopropyl alcohol and the orange dye are metabolized or exhaled. For topical application, systemic absorption is minimal (<1%), and absorbed drug is excreted predominantly via feces (biliary).
