Controlled Pulmonary Drug Delivery

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.

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.

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.

There has been a rapid evolution in the field of inhalation drug therapy, including new drugs, increased regulation and quality control, and strong pressure from generics. Inhalation Drug Therapy brings together the most current inhalation drug research, as well as practical developments and processes, into one essential guide. Focusing on inhalation products and specific equipment and techniques used in manufacturing and quality control, the book balances research with the industrial aspects of creating the drugs, and features a highly regarded author team with both academic and industry experience.

The respiratory tract has been used to deliver biologically active chemicals into the human body for centuries. However, the lungs are complex in their anatomy and physiology, which poses challenges to drug delivery. Inhaled formulations are generally more sophisticated than those for oral and parenteral administration. Pulmonary drug development is therefore a highly specialized area because of its many unique issues and challenges. Rapid progress is being made and offers novel solutions to existing treatment problems. Advances in Pulmonary Drug Delivery highlights the latest developments in this field.

Modeling and Control of Drug Delivery Systems provides comprehensive coverage of various drug delivery and targeting systems and their state-of-the-art related works, ranging from theory to real-world deployment and future perspectives. Various drug delivery and targeting systems have been developed to minimize drug degradation and adverse effect and increase drug bioavailability. Site-specific drug delivery may be either an active and/or passive process. Improving delivery techniques that minimize toxicity and increase efficacy offer significant potential benefits to patients and open up new markets for pharmaceutical companies.
