[Polyvinylpyrrolidone iodine--its significance in dermatology]

In an open comparative study, 40 patients suffering from pyoderma, combustion (1st and 2nd degrees), leg ulcer, or inflammatory white atrophy were treated with a topical preparation containing either polyvinyl pyrrolidone iodine or neomycin. Both preparations were well-tolerated. There was no local hypersensibility. With regard to the therapeutic effect, we did not observe any differences between the two groups of patients. We discuss the properties, modes of action, and contraindications, as well as the possible systemic influences of topically applied PVP iodine.
