CHLORAPREP ONE-STEP FREPP vs READYPREP CHG
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.
Chlorhexidine gluconate disrupts microbial cell membranes, causing leakage of cytoplasmic contents and cell death. Its cationic nature binds to negatively charged bacterial cell walls, providing persistent antimicrobial activity.
Topical antiseptic: apply to intact skin for 30 seconds and allow to dry for 30 seconds; single-use per patient.
No standard systemic dosing; used as a 4% chlorhexidine gluconate topical antiseptic solution applied once daily to entire body for preoperative skin preparation or for chlorhexidine bathing in infection prevention protocols.

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.
60 minutes (terminal) in patients with normal renal function; prolonged in renal 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.
Renal: ~100% unchanged via glomerular filtration. No biliary or fecal elimination.
