CHLORAPREP ONE-STEP FREPP vs HEXA-GERM
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.
HEXA-GERM is a topical antiseptic containing chlorhexidine gluconate, which disrupts microbial cell membranes and precipitates cell contents, leading to bacterial death.
Topical antiseptic: apply to intact skin for 30 seconds and allow to dry for 30 seconds; single-use per patient.
Intramuscular injection of 0.5 mL (containing 5 µg hexa-arginine conjugate) once weekly.

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 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 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 excretion of unchanged drug accounts for approximately 60-70% of elimination; hepatic metabolism (mainly via CYP3A4) accounts for 20-30%; fecal excretion is <5%.
