CHLORAPREP ONE-STEP SEPP vs POVIDONE IODINE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Chlorhexidine gluconate and isopropyl alcohol combination. Chlorhexidine disrupts bacterial cell membranes and precipitates cytoplasmic contents; isopropyl alcohol denatures proteins and dissolves lipids, providing rapid bactericidal activity.
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 2% chlorhexidine gluconate and 70% isopropyl alcohol solution topically to the surgical site for 30 seconds using the applicator; allow to dry for 30 seconds to 2 minutes. Single-use only.
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.

The terminal elimination half-life in plasma is approximately 7-10 hours after topical application, but due to extensive tissue binding, sustained local concentrations persist for up to 48 hours.
Iodide half-life approximately 2 days (48 hours); clinical context: prolonged in renal impairment, leading to accumulation.
Chlorhexidine is primarily excreted via feces (>90%) as unchanged drug, with minimal renal excretion (<1%). A small amount is metabolized in the liver to inactive metabolites.
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.
