Subject Physical Principles of Dosage Forms is taught in the third year of study and builds on Biophysics and Physical Chemistry. The aim of the subject is to provide comprehensive information on the basic physical principles used in formulating and stabilizing pharmaceutical forms. In particular, it describes the properties of the solid phase (active compounds and Excipients), liquid phase and dispersion (molecular, colloidal and macrodispersion) and interfacial phenomena that are related to the physical and chemical stability of pharmaceutical products. In the subject of the Physical Principles of Dosage Forms, students will also be acquainted with the basics of polymer chemistry necessary to understand the structure, properties and function of these substances in pharmaceutical formulations and modern drug delivery systems. The basic principles of pharmaceutical nanotechnologies will also be included. Considering that the physical properties of materials and physical processes at the interface significantly affect the resulting quality of pharmaceutical formulations, understanding these principles is essential for further study of pharmaceutical technology and dosage forms. From this perspective, the Physical Principles of Dosage Forms can be viewed as an interdisciplinary subject with a linking function between fundamental subjects taught in the first section of study and highly specialized pharmaceutical technology. Topics: Solution properties, Solid-phase, Solid-phase properties, Solubility and dissolution, Diffusion, Interfacial phenomena in pharmaceutical Systems, Pharmaceutical surfactants, Pharmaceutical polymers, Polymer systems, Rheology, Dispersion systems and their stability, Nanotechnology.
