We are delighted to present “Principles of Industrial Pharmacy–I: Essential Concepts in Drug Manufacturing”, a textbook designed to provide pharmacy students with a thorough understanding of the fundamental principles involved in pharmaceutical manufacturing and dosage form development. The pharmaceutical industry is a dynamic and rapidly evolving sector that demands a strong foundation in formulation science, production technology, quality assurance, and regulatory compliance. This book aims to equip students with the essential knowledge required to meet these challenges.

The content has been carefully structured in accordance with the current pharmacy curriculum and covers key topics such as preformulation studies, tablet and capsule technology, parenteral and ophthalmic preparations, cosmetic formulations, pharmaceutical aerosols, and packaging systems. Each chapter emphasizes both theoretical concepts and practical applications, enabling learners to appreciate the scientific basis of drug manufacturing processes and quality control practices.

Special efforts have been made to present the subject matter in a clear, concise, and student-friendly manner. Tables, illustrations, flowcharts, and review questions have been included to facilitate better understanding and effective learning. We hope that this book will serve as a valuable academic resource for students, educators, researchers, and professionals in the field of pharmaceutical sciences.

We welcome constructive suggestions and feedback for further improvement of future editions.
