CHLORAPREP ONE-STEP vs GAMOPHEN
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.
Gamophen contains chlorhexidine gluconate, a cationic bisbiguanide that disrupts microbial cell membranes by binding to negatively charged phosphate groups on bacterial cell walls, leading to leakage of intracellular contents and cell death. It also inhibits bacterial enzymes and has broad-spectrum antimicrobial activity against gram-positive and gram-negative bacteria, fungi, and some viruses.
Apply chlorhexidine 2% and isopropyl alcohol 70% solution to the surgical site as a single preoperative skin preparation; no additional scrubbing or rubbing required.
GAMOPHEN is not a recognized pharmaceutical drug. Please verify the drug name.

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 18-32 hours in adults, prolonged in renal impairment (up to 60 hours in severe cases).
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 (50-70%) and glucuronide conjugates; biliary/fecal elimination accounts for <10%.
