CHLORAPREP ONE-STEP vs HEXA-GERM
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.
HEXA-GERM is a topical antiseptic containing chlorhexidine gluconate, which disrupts microbial cell membranes and precipitates cell contents, leading to bacterial 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.
Intramuscular injection of 0.5 mL (containing 5 µg hexa-arginine conjugate) once weekly.

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 6-8 hours in patients with normal renal function; extends to 20-40 hours in severe renal impairment (CrCl <30 mL/min).
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 excretion of unchanged drug accounts for approximately 60-70% of elimination; hepatic metabolism (mainly via CYP3A4) accounts for 20-30%; fecal excretion is <5%.
