title: Suitability of a propanolic PVP-iodophor preparation as preoperative skin disinfectant: germicidal activity and chemical stability.
abstract: The preparation Solutio Betadini propanolica 3% w/w, used as a pre-operative skin disinfectant was examined for its germicidal activity and its chemical stability. The additive activity of iodine and propanol resulted in a wide range of antimicrobial activity against bacteria, including bacterial spores, and fungi, with a rapid onset and sustained duration of action. The solution is easily manufactured and analyzed, its stability is guaranteed for 6 months. Because of its staining property, there is no need of coloured additives to mark the disinfected area.
