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.
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.
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.
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.

2-7 days for iodine, prolonged in renal impairment; clinical context: topical use has minimal systemic absorption.
Terminal half-life approximately 12-24 hours; may be prolonged in hepatic impairment.
Renal: >90% as iodide; biliary/fecal <10%.
Primarily renal (10-30% unchanged) and biliary/fecal (majority as metabolites).
