CHLORAPREP SINGLE SWABSTICK vs POVIDONE IODINE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Chlorhexidine gluconate, a bisbiguanide antiseptic, disrupts microbial cell membranes and precipitates cytoplasmic contents at bactericidal concentrations.
Povidone-iodine is an iodophor that releases free iodine upon contact with skin or mucous membranes. Free iodine penetrates microbial cell walls and oxidizes essential cellular components, including proteins, nucleotides, and fatty acids, leading to rapid microbial death. It exhibits bactericidal, fungicidal, and virucidal activity.
Apply topically to intact skin as a single use swabstick. Allow to dry for 3 minutes. No frequency specified for single application.
Povidone-iodine is a topical antiseptic; no systemic dosing. For skin preparation: apply 10% solution to intact skin and allow to dry for 1-2 minutes. For surgical hand scrub: 7.5% or 10% solution, scrub for 5 minutes. For oral rinse: 1% solution, 10 mL swish for 30 seconds, repeat every 4 hours as needed.

Chlorhexidine: terminal half-life approximately 3-5 hours after cutaneous application; prolonged with repeated use due to dermal reservoir effect. p-Chloroaniline: terminal half-life 10-12 hours.
Iodide half-life approximately 2 days (48 hours); clinical context: prolonged in renal impairment, leading to accumulation.
Renal (minimal, <1% as unchanged drug); fecal/biliary (not significant); primarily metabolized to p-chloroaniline and subsequently excreted as conjugates in urine.
Renal elimination of iodide; free iodine (I2) is rapidly converted to iodide in blood; ~90% of absorbed iodide excreted renally; remainder in feces, sweat, and saliva.
