Pharmaceutical particulate science underpins a wide range of solid dosage forms, from orally delivered capsules, tablets, and powders to parenterally administered suspensions and aerosols for a range of topical applications, including skin and mucosal sites. Dividing the topics that require attention into the manufacturing origins of the particles, the physicochemical and performance properties, and the methods of measurement from which the quality of the product can be established encompasses the major areas of consideration. Here an overview of the approach taken throughout the book is given with the intent of defining the connection between each of the areas presented.
