[Topical antiseptic agents].

Topical therapy is an important domain in the treatment of dermatological diseases in the 21st century. Because multiresistant bacteria are becoming an increasing issue in medical care of chronic diseases, it is important to develop appropriate therapeutic management for acute and chronic dermatoses. The current discussion about the skin microbiota shows the importance of preserving the resident skin flora. There is a need for alternatives to topical antibiotics, e. g. topical antiseptics, which should be safe, fast, and effective but not allergenic or toxic. Even with frequent and prolonged application it is important that they do not develop a resistance. This article focusses on the use of antiseptics for medical indications. Mechanisms of action, tolerability, maximum concentrations, and possible contraindications are discussed and examples of extemporaneous antiseptic preparations are provided.
