Physical Pharmaceutics – I is a core subject in pharmaceutical sciences that lays the groundwork for understanding the physical and chemical principles governing drug formulation and development. It provides the essential scientific base upon which students can build their knowledge of pharmaceutics and drug delivery systems. The subject deals with the study of physicochemical properties of both drug molecules and excipients, and explains how these properties influence the stability, bioavailability, and therapeutic effectiveness of pharmaceutical dosage forms.
This book on Physical Pharmaceutics – I has been prepared with the objective of presenting the concepts in a clear, simple, and systematic manner to meet the academic requirements of undergraduate pharmacy students. The topics covered include states of matter, phase equilibria, solutions, colligative properties, solubility, partition coefficient, and other related areas. Each concept has been explained in a concise manner with emphasis on its pharmaceutical significance, so that learners can easily connect theory with practical applications.
The content has been arranged in a student-friendly format, integrating both fundamental principles and their industrial relevance. Special care has been taken to make the subject more approachable by avoiding unnecessary complexity, while ensuring that the scientific depth is maintained. It is our belief that this text will not only help students in their examinations but also assist them in developing a deeper appreciation of pharmaceutics as a discipline.
We sincerely hope this book serves as a valuable guide for pharmacy learners in their academic journey.
