About Book
A Textbook of Drug Delivery Systems is a comprehensive academic resource crafted to align
with the PCI syllabus for the subject Drug Delivery Systems (MPH 102T). This book serves as a
valuable guide for postgraduate pharmacy students, researchers, and professionals seeking in-
depth understanding of advanced drug delivery technologies. It systematically covers the
principles, design, and applications of various novel drug delivery systems, beginning with
controlled drug delivery, highlighting their definitions, rationale, advantages, disadvantages, and
drug selection criteria. The book delves into formulation strategies such as diffusion, dissolution,
and ion exchange mechanisms, and explains the physicochemical and biological factors crucial
for sustained and controlled release. A dedicated section on polymers elaborates on their types,
properties, and roles in drug delivery. Microencapsulation techniques, including microspheres,
microcapsules, and microparticles, are presented with emphasis on preparation methods and
pharmaceutical applications.
Overall, this textbook integrates theoretical concepts with practical applications, making it a
reliable reference for coursework, research projects, and formulation development. It equips
readers with a solid foundation to understand current trends and future directions in drug
delivery, fostering innovation in pharmaceutical sciences.
