BETADINE vs CHG SCRUB
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 disrupts bacterial cell membranes, leading to leakage of intracellular contents and cell death. It also binds to proteins and inhibits bacterial enzymes.
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 5 mL to wet skin, scrub for 2 minutes, rinse thoroughly. Use undiluted.

2-7 days for iodine, prolonged in renal impairment; clinical context: topical use has minimal systemic absorption.
Approximately 2 hours (terminal); prolonged in renal impairment.
Renal: >90% as iodide; biliary/fecal <10%.
Primarily renal (90% unchanged); <5% biliary/fecal.
