[Modern topical drugs-new developments in galenics and pharmacology].

Abstract

The importance of topically applied pharmaceuticals, especially for the treatment of dermatological diseases, is still essential. Thanks to detailed knowledge of the organisation and function of the physicochemical barrier of the skin, new galenic concepts have increasingly been developed to market maturity in recent years. Colloidal drug carrier systems in particular, but also targeted physicochemical modifications of matrices are used to optimise the cutaneous bioavailability of topically applied drugs. In addition, new molecules are increasingly becoming available for the development of these preparations or drugs known from systemic therapy are being formulated into topicals. Against this background, dermatopharmacology is also developing more and more into a highly specialised science in this area, which is producing innovative concepts for the therapy of special indications. In addition to the classic small-molecule drugs, biotechnological molecules are increasingly finding their way into application, so that a modern age of dermatopharmacology has dawned, which will open up previously unimagined possibilities for topical therapy now and in the coming years.
