Abstract

The aim of this proposal is to establish a platform for the development of topical delivery systems that ensure the targeted and sustained release of drugs to the epithelial tissue that forms the skin and the cornea. The design of drug delivery systems for topical treatment should take into account the integrity of the epithelium where they will be applied, the layer of this epithelium in which the disease is inserted, the physicochemical characteristics of the substances to be administered and the rate that these substances must be released to have the intended action. Due to the complexity to correlate all these variables, the project is divided into 2 parts. In the first one, delivery systems will be developed for application in non-intact epithelia, aimed at treating chronic wounds. The current market lacks products that combine substances that are effectives in the various stages of the healing process, that release these substances in a programmed period and that protect the wounds against physical and microbiological damage. Thus, the first part of this project proposes the development of delivery systems for macromolecules in a step, using fibroin based delivery systems, and for small molecules, but associated in a same system, in other step. The second part of the project aims at the development of delivery systems for application in intact and keratinized epithelia, such as skin tumors, where it is necessary to extrapolate the keratinized barrier and carry large quantities of active substance, released during long periods, for layers of the epithelium that require treatment. In this part of the project, the influence of iontophoresis and ultrasound in the release rate of drugs dispersed in liquid crystalline systems will be explored for the first time. (AU)
