Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Povidone-iodine is an iodophor that releases free iodine, which oxidizes and iodinates microbial proteins and enzymes, leading to rapid broad-spectrum microbicidal activity against bacteria, fungi, viruses, and protozoa.
Chlorhexidine gluconate and isopropyl alcohol combination. Chlorhexidine disrupts bacterial cell membranes and precipitates cytoplasmic contents; isopropyl alcohol denatures proteins and dissolves lipids, providing rapid bactericidal activity.
Apply topically as a 10% povidone-iodine solution to the affected area 1-3 times daily; for preoperative skin preparation, apply as a single scrub for 5 minutes; for mouthwash/gargle, use 1% solution (diluted 1:10) 4 times daily; for vaginal use, 10% solution as a douche once daily. Not for systemic use.
Apply 2% chlorhexidine gluconate and 70% isopropyl alcohol solution topically to the surgical site for 30 seconds using the applicator; allow to dry for 30 seconds to 2 minutes. Single-use only.

2-7 days for iodine, prolonged in renal impairment; clinical context: topical use has minimal systemic absorption.
The terminal elimination half-life in plasma is approximately 7-10 hours after topical application, but due to extensive tissue binding, sustained local concentrations persist for up to 48 hours.
Renal: >90% as iodide; biliary/fecal <10%.
Chlorhexidine is primarily excreted via feces (>90%) as unchanged drug, with minimal renal excretion (<1%). A small amount is metabolized in the liver to inactive metabolites.
