BETADINE vs HIBISTAT
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.
Inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis and death. Active against susceptible gram-positive bacteria.
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.
1.5 mg/kg intravenously every 6 hours; maximum 120 mg per dose.

2-7 days for iodine, prolonged in renal impairment; clinical context: topical use has minimal systemic absorption.
Terminal elimination half-life is 2.5–3.5 hours in patients with normal renal function; prolonged in renal impairment, requiring dose adjustment.
Renal: >90% as iodide; biliary/fecal <10%.
Approximately 90% of absorbed dose excreted renally as unchanged drug; <5% in feces via biliary elimination.
