Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Chlorhexidine gluconate disrupts bacterial cell membranes, leading to leakage of intracellular contents and cell death. It also binds to proteins and inhibits bacterial enzymes.
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.
Apply 5 mL to wet skin, scrub for 2 minutes, rinse thoroughly. Use undiluted.
Topical antiseptic: apply to intact skin for 30 seconds and allow to dry for 30 seconds; single-use per patient.

Approximately 2 hours (terminal); prolonged in renal impairment.
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.
Primarily renal (90% unchanged); <5% biliary/fecal.
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.
