he bioadhesive polymeric films as topical drug delivery systems are interesting alternatives to improve the pharmacotherapy and patient compliances. New derivate biomaterials based on weisocyanate- dendronized PVP- crosslinked chitosan and loaded with ciprofloxacin (CIP), as model drug, were used to prepare bioadhesive films. Relevant in vitro/in vivo attributes to define main physicochemical and biopharmaceutical characteristics for topical wound-healing applications were evaluated. A high proportion of CIP, uniformly dispersed along throughout the film, was loaded. An extended release of CIP and different behaviors of release profiles, depending on the presence of dendron, were observed. The films loaded with CIP were effective in inhibiting the growth of both Gram positive and Gram negative bacteria. In addition, biocompatibility and bioadhesion into conjuntival-sacs of the rabbits suggests that these films have good properties to be applied over skin wounds for topical application
