BETADINE vs READYPREP CHG
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 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.
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.
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.

2-7 days for iodine, prolonged in renal impairment; clinical context: topical use has minimal systemic absorption.
60 minutes (terminal) in patients with normal renal function; prolonged in renal impairment.
Renal: >90% as iodide; biliary/fecal <10%.
Renal: ~100% unchanged via glomerular filtration. No biliary or fecal elimination.
