The field of drug delivery is constantly evolving, with new and innovative technologies being developed all the time. This is because there is a growing need for more effective and targeted ways to deliver drugs to the body. Novel drug delivery systems (NDDS) are at the forefront of this evolution. NDDS is designed to overcome the limitations of traditional drug delivery methods, such as poor bioavailability, short half-life, and side effects. They can also be used to target drugs to specific tissues or cells, which can improve efficacy and reduce toxicity. This book provides an overview of the latest advances in NDDS. It covers a wide range of topics, including microencapsulation, liposomes, nanoparticles, and implantable devices. The book also discusses the regulatory and ethical considerations of NDDS. The book is intended for students, researchers, and healthcare professionals who are interested in learning more about NDDS. It is also a valuable resource for anyone who wants to stay up-to-date on the latest developments in this rapidly growing field.
