BETADINE vs PHISOHEX
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.
Disrupts bacterial cell wall synthesis by binding to the bacterial ribosome and inhibiting protein synthesis; also has surfactant properties that disrupt bacterial cell membrane integrity.
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 topically as a 3% emulsion to affected area, rinse thoroughly; typically used 1-2 times daily for up to 10 days.

2-7 days for iodine, prolonged in renal impairment; clinical context: topical use has minimal systemic absorption.
Terminal elimination half-life approximately 6-7 hours in adults with normal renal function. Prolonged in renal impairment (up to 20 hours) due to reduced clearance of active metabolite (pentachlorophenol).
Renal: >90% as iodide; biliary/fecal <10%.
Renal (biliary/fecal negligible). Up to 10% of dose excreted unchanged in urine; remainder as metabolites (glucuronide and sulfate conjugates).
