"This book offers a comprehensive overview of the epidemiology, etiology, and pathophysiology of Chronic Obstructive Pulmonary Disease (COPD). It addresses the limitations of existing drug delivery methods and explores advanced delivery systems to overcome these challenges, providing an exhaustive account of their intricate mechanisms. The introductory chapters elucidate pathways responsible for COPD progression, followed by a detailed analysis of established biomarkers and potential targets in contemporary COPD therapy. Subsequent chapters provide insights into ongoing treatment modalities, their efficacy, drawbacks, and prospective solutions to counter the setbacks of COPD therapy. The subsequent section covers state-of-the-art drug delivery technologies and novel drug formulations designed to enhance drug deposition and absorption in COPD lungs. It further explores a methodical yet coordinated explanation of targeted personalized therapies and emerging approaches, including nanoparticles, polymeric carriers, and vesicular delivery systems. Towards the end, the book discusses ongoing and completed clinical trials encompassing the management of COPD through advanced drug delivery approaches. It serves as a valuable resource for professionals, scientists, academicians, and clinicians specializing in respiratory health"-- Provided by publisher.
