New screening methodology for selection of polymeric matrices for transdermal drug delivery devices

Transdermal drug delivery systems, such as patches, are viewed as one the best technologies that enhance greater patient compliance thus providing the desired therapeutic results. However, one of the main challenges is to find the right polymeric matrix that will provide the desired active therapeutic concentration. This is usually accomplished empirically and is not always the effective approach. In this study, the authors describe a predictive screening methodology based on material parameters to identify materials that will accomplish therapeutic targets.
