Respiratory Drug Delivery 1989

The focus of this book is on subjects related to drug delivery to the lung. The text spans topics from aerosol deposition through pharmaceutical chemistry and formulation to the final clinical evaluation of pharmaceutical products. Utilizing a multi-disciplinary approach, the chapters consider toxicology from the point of view of drugs and pharmaceutical excipients used in aerosols.

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.

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.

This book focuses on the aerosol treatment of lung diseases, recent improvements in the understanding of proper dosage, and major innovations in device technology applied to clinical practice. Examines the behavior of inspired spherical particles in the respiratory tract!Featuring over 1300 references, drawings, tables, and photographs.

In treating diseases of the respiratory tract, the direct administration of drugs has great advantages in terms of clinical efficiency. This book reviews the most important recent developments in drug delivery systems to the respiratory tract. Starting with a detailed description of lung strucure and function, successive chapters investigate the usefulness of the pulmonary presention of beta-agonists, steroids and chromoglycate, and explain metabolic function and susceptibility to chemical damage from the environment, showing that the lung is far from being a passive organ. Further contributions demonstrate the importance of mucus in humidification, particle capture and particle removal before attention is given to the practical problems of drug delivery and the commercially viable devices available to the pharmaceutical technologist: the metered dose inhaler, the powder inhaler, and the jet nebuliser. The final chapter examines the future role of intranasal delivery systems, based upon the principles described.

Handbook of Lung Targeted Drug Delivery Systems: Recent Trends and Clinical Evidences covers every aspect of the drug delivery to lungs, the physiology and pharmacology of the lung, modelling for lung delivery, drug devices focused on lung treatment, regulatory requirements, and recent trends in clinical applications. With the advent of nano sciences and significant development in the nano particulate drug delivery systems there has been a renewed interest in the lung as an absorption surface for various drugs. The emergence of the COVID-19 virus has brought lung and lung delivery systems into focus, this book covers new developments and research used to address the prevention and treatment of respiratory diseases. Written by well-known scientists with years of experience in the field this timely handbook is an excellent reference book for the scientists and industry professionals.
