CHLORAPREP ONE-STEP vs CHLORAPREP SINGLE SWABSTICK
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, a bisbiguanide antiseptic, disrupts microbial cell membranes and precipitates cytoplasmic contents at bactericidal concentrations.
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 as a single use swabstick. Allow to dry for 3 minutes. No frequency specified for single application.

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: terminal half-life approximately 3-5 hours after cutaneous application; prolonged with repeated use due to dermal reservoir effect. p-Chloroaniline: terminal half-life 10-12 hours.
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).
Renal (minimal, <1% as unchanged drug); fecal/biliary (not significant); primarily metabolized to p-chloroaniline and subsequently excreted as conjugates in urine.
