This book focuses on the needs of postgraduate studies. Physicochemical properties of materials (drugs & excipients) form an essential part of Physical Pharmaceutics and advanced topics are explained. Nanotechnology demands the determination of particle size as a crucial point in the preformulation of dosage forms. Polymers have been widely used in the conventional formulations and novel controlled drug delivery systems. The evaluation of the release mechanisms is the key to the product development. The characterization of materials by the thermal analysis and X-ray diffraction becomes important as pharmacopoeial necessities. These are based on the improvements as needed by the pharmaceutical industry and research.

   Special emphasis is given to include the following:
          1. Conceptualization of principles
          2. Applications of principles
          3. A number of illustrations
          4. Comments type questions
          5. Objectives and mind maps
          6. Question bank
