The comprehensive book Drug Delivery Systems explores the intricate and evolving world of
advanced drug delivery technologies. It provides an in-depth understanding of the latest
developments in this field, making it an invaluable resource for pharmacy graduates,
postgraduates, and educators in pharmaceutical sciences, shaping the future of drug delivery
practices. The content is designed to provide an in-depth understanding of Sustained Release (SR)
and Controlled Release (CR) formulations, highlighting their basic concepts, advantages,
disadvantages, and the factors influencing their development. Readers will gain insights into the
physicochemical and biological approaches for SR/CR formulations and the mechanisms
governing drug delivery from these systems.
The book also covers the vital role of polymers in drug delivery, discussing their classification,
properties, and diverse applications. Personalized medicine, a rapidly growing field, is explored
through topics such as pharmacogenetics, customized drug delivery systems, bioelectronic
medicines, 3D printing of pharmaceuticals, and telepharmacy.
Rate-controlled drug delivery systems are examined in detail, including principles, types, and
activation methods such as mechanically, pH, enzyme, and osmotically activated systems. The text
also addresses feedback-regulated drug delivery systems, emphasizing the principles and
fundamentals that guide their design.
Gastro-retentive drug delivery systems are discussed with a focus on modulating GI transit time,
while buccal drug delivery systems are explored through the principles of mucoadhesion,
mechanisms of drug permeation, and formulation techniques. The book further investigates ocular
and transdermal drug delivery systems, providing an understanding of the barriers to drug
permeation and strategies to overcome them.
Additionally, the book covers the challenges and solutions in protein and peptide delivery,
including formulation and evaluation methods, and offers insights into innovative vaccine delivery
systems, such as single-shot vaccines, mucosal delivery, and transdermal approaches.
