Preparation and Evaluation Methods of Coamorphous: Towards Applications

Research on coamorphous system has increased in recent years. Coamorphous can be defined as an amorphous composite in which the interaction sites are fixed between two or more components, attracting attention as a new amorphous state to replace solid dispersions. The most difficult aspect of characterizing coamorphous is proving the absence of crystals. It will be important to select correct evaluation methods. In this study, the preparation, evaluation and analytical methods are described in terms of advantages and disadvantages. In addition, applications are presented from own research.
