CHLORAPREP ONE-STEP vs PHISOHEX
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.
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.
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 as a 3% emulsion to affected area, rinse thoroughly; typically used 1-2 times daily for up to 10 days.

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.
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 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 (biliary/fecal negligible). Up to 10% of dose excreted unchanged in urine; remainder as metabolites (glucuronide and sulfate conjugates).
