RESUMO
some specific requirements for the military medicines which are used for treatment of special weapon injury and harsh environment induced diseases, such as administrative routes, formulations, packages and period of validity. Research and development of new pharmaceutical technologies have become more and more important for meeting the requirement and improving the serviceability of such medicines. Auto-injection, fast-dissolving technology, sustained or controlled release technologies are widely used for the purpose. In this paper, based on the analysis of the specific requirements, the current progress of new pharmaceutical technologies and their application in special military medicines are reviewed.
