CHLORAPREP ONE-STEP FREPP vs CHLORHEXIDINE GLUCONATE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Chlorhexidine gluconate disrupts bacterial cell membranes and precipitates cell contents, providing rapid bactericidal activity. Isopropyl alcohol denatures proteins and disrupts cell membranes, enhancing antimicrobial effect.
Cationic bisbiguanide that disrupts microbial cell membranes by binding to negatively charged cell wall components, increasing permeability and causing leakage of cytoplasmic contents; also inhibits bacterial enzymes and precipitates cytoplasmic constituents.
Topical antiseptic: apply to intact skin for 30 seconds and allow to dry for 30 seconds; single-use per patient.
Oral rinse: 15 mL of 0.12% solution swished in mouth for 30 seconds twice daily; topical: apply 2% cream or lotion to affected area 2-3 times daily.

Not applicable, as systemic absorption is negligible. For absorbed chlorhexidine, terminal half-life is approximately 1-2 hours due to rapid clearance, but this is clinically irrelevant.
Terminal half-life approximately 12-24 hours; may be prolonged in hepatic impairment.
Chlorhexidine gluconate and isopropyl alcohol are not significantly absorbed systemically after topical application. For the minimal absorbed fraction, chlorhexidine is primarily excreted unchanged in feces via biliary elimination (~90%), with renal excretion accounting for <1%. Isopropyl alcohol is metabolized to acetone and excreted via lungs and urine; however, systemic absorption is negligible with intact skin.
Primarily renal (10-30% unchanged) and biliary/fecal (majority as metabolites).
