Every year new drugs appear on the market. Information about the therapeutic innovation is contained in many heterogeneous sources. A physician needs to identify easily and fast the whole of the drug innovations relative to his sphere of activity, to understand the nature of these innovations and their potential impacts on the practice. We analyzed the available sources and the nature of this information which can be found after the marketing drug. We explored the American, European including French sources. We identified the sources that constitute the base in identification of pharmaceutical innovation. We explored its structure and format to know if they could be used in the development of therapeutic monitoring tool. We selected the sources that help to characterize pharmaceutical innovation concerning to type of innovation and according to impact of the new drug. We proposed a tool which identifies the drugs prescribed for pathology ―type 2 of diabetes‖ using DailyMed source. The tool allows finding the type of innovation and its impact. This work has identified the main sources of information available at the moment of drug marketing. Each of the described sources in this paper is important, but insufficient to characterize the pharmaceutical innovation.
