CHLORAPREP ONE-STEP vs PHISO-SCRUB
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.
Phiso-Scrub is a topical antiseptic containing triclosan, which inhibits bacterial fatty acid synthesis by targeting enoyl-acyl carrier protein reductase (FabI), leading to disruption of cell membrane integrity and bacterial cell 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.
Topical application to affected area once daily; chlorhexidine gluconate 4% scrub, lather for 3-5 minutes, rinse thoroughly.

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.
Approximately 8-12 hours in patients with normal renal function (CrCl >90 mL/min). Half-life is significantly prolonged in renal impairment (up to 40 hours in ESRD).
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).
Primarily renal excretion of unchanged drug (approximately 70-80% of absorbed dose). Biliary/fecal elimination accounts for the remainder (20-30%).
