PHYSICAL PHARMACEUTICS-I (Practical)

Physical Pharmaceutics forms the backbone of pharmaceutical sciences, providing essential knowledge about the physicochemical principles that govern drug formulation, development, and performance. Understanding these principles is crucial for students and researchers to design safe, effective, and stable pharmaceutical dosage forms.
This book, Physical Pharmaceutics–I, has been carefully designed to provide a comprehensive practical approach to core concepts through well-structured experiments. It covers a wide range of essential topics including solubility, partition coefficient, surface tension, adsorption isotherms, micellization, and stability constants. Each experiment included in this book has been selected to strengthen fundamental understanding while also developing practical laboratory skills.
The experiments such as determination of solubility at room temperature, partition coefficient of various systems (benzoic acid, iodine, and succinic acid), evaluation of HLB number, adsorption studies using Freundlich and Langmuir isotherms, determination of critical micellar concentration (CMC), and analysis of complex formation (PABA–caffeine and cupric–glycine) are presented in a clear and systematic manner. Additionally, important physicochemical parameters like pKa determination using different methods and surface tension measurements using stalagmometer techniques are included to provide a holistic learning experience.
Special care has been taken to maintain simplicity, accuracy, and relevance throughout the book. It is hoped that this book will not only help students perform experiments effectively but also develop a deeper understanding of the subject.
I sincerely hope that this book will serve as a valuable resource for students, teachers, and researchers in the field of pharmaceutical sciences.
