CHLORAPREP ONE-STEP vs HIBISTAT
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.
Inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis and death. Active against susceptible gram-positive bacteria.
Apply chlorhexidine 2% and isopropyl alcohol 70% solution to the surgical site as a single preoperative skin preparation; no additional scrubbing or rubbing required.
1.5 mg/kg intravenously every 6 hours; maximum 120 mg per dose.

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 is 2.5–3.5 hours in patients with normal renal function; prolonged in renal impairment, requiring dose adjustment.
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).
Approximately 90% of absorbed dose excreted renally as unchanged drug; <5% in feces via biliary elimination.
