Update On Polymers For Pulmonary Drug Delivery

Pulmonary drug delivery has been a rapidly expanding field, moving from the traditional propellant based metered dose inhaler delivery of small asthma drugs, to a broader landscape of new devices and novel drugs for local and systemic delivery. The field has greatly expanded yet the tools for pulmonary drug delivery systems have not kept pace with the potential applications. One of the key developments has been the use of polymers to achieve better control of pulmonary drug delivery. This has the potential to expand the toolbox available for researchers in the field to deliver their new chemical entities successfully to the lung. This book reviews the use of polymers in pulmonary drug delivery, encompassing polymers from their use in devices and packaging, in addition to their use as excipients in formulations delivered to the airways. The book is arranged by application and extensively reviews the technical and patent literature. This is the first volume totally dedicated to polymers in pulmonary drug delivery and should be the resource of choice for those in the field, especially managers in the pharma/biotech industry. Naturally, the text will be of great interest to academics and graduate students. Finally, regulatory affiliated scientists will also find this resource invaluable.

The subsequent book chapters elaborate on various functional excipients such as chitosan, cyclodextrins, and Vitamin E-TPGS to attain local and systemic therapeutic action. There are book chapters focused on diverse novel carrier systems such as hydrogels, quantum dots, metal-organic framework, and prodrug approach. Additionally, book also contains chapters, exclusively dedicated to biologicals and numerical simulation in pulmonary therapeutics. The book chapters follow a sequential order, beginning with the pulmonary relevance of technology or polymeric materials, carrier synthesis schemes, current technical state-of-art, along with clinical, industrial, and regulatory aspects. Each chapter contains a future perspective section that will systematically reflect the current state of advances in pulmonary drug delivery. It also offers a practical basis for audience to understand the design and function of the delivery systems for better therapeutic outcomes. The book provides balanced views by considering the investigations from various scientific domains and industrial knowledge. Briefly, this book aims to collect, analyse, and bring together the latest developments in pulmonary drug delivery with more focus on materials and technologies. Indeed, this book is a valuable source for readers and researchers who wish to learn more about the advances in pulmonary drug delivery systems.

This book comprehensively reviews the recent developments of natural polymers for drug delivery systems in various lung disorders. The initial chapter provides a brief introduction to lung diseases with a focus on the current landscape of natural polymers and trends in understanding the disease pathology. Several chapters of the book devoted to the latest technologies and advances in drug delivery systems include practical solutions on designing more effective drug delivery systems based on natural polymers that can be used in the management of lung diseases. Further, the book presents biodegradable and bio-reducible- natural polymers- based drug delivery systems for lung diseases. Towards the end, the book examines future prospects and challenges of natural polymers-based drug delivery systems in combating lung diseases. This book is useful for phytochemists, formulation/drug delivery, biological and translational researchers and clinicians working in the field of lung disorders.

The preferred route for drug delivery remains the oral route, but oral drug delivery has now developed beyond traditional dosage forms such as tablets and capsules. Nowadays it is possible to use polymers to allow drugs to be targeted to specific sites in the gastrointestinal tract, and to extend the drug release profile. In addition, polymers can be engineered to allow oral delivery of such complex molecules as proteins, peptides, and even genes. This book gives a comprehensive summary of oral drug delivery systems, both conventional and novel, and the ways in which polymers have been adapted for these systems. Particular attention is devoted to gastrointestinal physiology and the physio-chemical properties of polymers in order to understand the factors affecting their performance in practice. This update will interest everyone involved in the pharmaceutical world, whether in academia or in industry. It will be of particular value to those responsible for designing new oral drug delivery systems involving polymers. It will provide a useful reference text both for researchers and manufacturers, and will also be a helpful introduction for students of all levels to the application of polymers in pharmacy.

Drug therapy via inhalation route is at the cutting edge of modern drug delivery research. There has been significant progress on the understanding of drug therapy via inhalation products. However, there are still problems associated with their formulation design, including the interaction between the active pharmaceutical ingredient(s) (APIs), excipients and devices. This book seeks to cover some of the most pertinent issues and challenges of such formulation design associated with industrial production and desirable clinical outcome. The chapter topics have been selected with a view to integrating the factors that require consideration in the selection and design of device and formulation components which impact upon patient usability and clinical effectiveness. The challenges involved with the delivery of macromolecules by inhalation to both adult and pediatric patients are also covered. Written by leading international experts from both academia and industry, the book will help readers (formulation design scientists, researchers and post-graduate and specialized undergraduate students) develop a deep understanding of key aspects of inhalation formulations as well as detail ongoing challenges and advances associated with their development.

The pace of new research and level of innovation repeatedly introduced into the field of drug delivery to the lung is surprising given its state of maturity since the introduction of the pressurized metered dose inhaler over a half a century ago. It is clear that our understanding of pulmonary drug delivery has now evolved to the point that inhalation aerosols can be controlled both spatially and temporally to optimize their biological effects. These abilities include controlling lung deposition, by adopting formulation strategies or device technologies, and controlling drug uptake and release through sophisticated particle technologies. The large number of contributions to the scientific literature and variety of excellent texts published in recent years is evidence for the continued interest in pulmonary drug delivery research. This reference text endeavors to bring together the fundamental theory and practice of controlled drug delivery to the airways that is unavailable elsewhere. Collating and synthesizing the material in this rapidly evolving field presented a challenge and ultimately a sense of achievement that is hopefully reflected in the content of the volume.

Polymers have played a critical role in the rational design and application of drug delivery systems that increase the efficacy and reduce the toxicity of new and conventional therapeutics. Beginning with an introduction to the fundamentals of drug delivery, Engineering Polymer Systems for Improved Drug Delivery explores traditional drug delivery techniques as well as emerging advanced drug delivery techniques. By reviewing many types of polymeric drug delivery systems, and including key points, worked examples and homework problems, this book will serve as a guide to for specialists and non-specialists as well as a graduate level text for drug delivery courses.
