Download or read book Drug Delivery to the Respiratory Tract written by David Ganderton and published by . This book was released on 1987 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Pulmonary Drug Delivery written by Ali Nokhodchi and published by John Wiley & Sons. This book was released on 2015-08-03 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Advances in Pulmonary Drug Delivery written by Philip Chi Lip Kwok and published by CRC Press. This book was released on 2016-12-19 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Investigation and Optimization of a Solvent written by Swati Agrawal and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Dry powder inhalers (DPIs) are commonly used to deliver drugs to the lungs. The drug particles used in these DPIs should possess a number of key properties. These include an aerodynamic particle size 5[micro]m and particle crystallinity for long term formulation stability. The conventionally used micronization technique to produce inhalation particles offers limited opportunities to control and optimize the particle characteristics. It is also known to induce crystalline disorder in the particles leading to formulation instability. Hence, this research project investigates and optimizes a solvent/anti-solvent crystallization process capable of directly yielding inhalation particles using albuterol sulfate (AS) as a model drug. Further, the feasibility of the process to produce combination particles of AS and ipratropium bromide monohydrate (IB) in predictable proportions and in a size suitable for inhalation is also investigated. The solvent / anti-solvent systems employed were water / ethyl acetate (EA) and water / isopropanol (IPA). Investigation and optimization of the crystallization variables with the water / EA system revealed that particle crystallinity was significantly influenced by an interaction between the drug solution / anti-solvent ratio (Ra ratio), stirring speed and crystal maturation time. Inducing a temperature difference between the drug solution and anti-solvent (Tdrug solution Tanti-solvent) resulted in smaller particles being formed at a positive temperature difference of 65°C. IPA was shown to be the optimum anti-solvent for producing AS particles (IPA-AS) in a size range suitable for inhalation. In vitro aerosol performance of these IPA-AS particles was found to be superior compared to the conventionally used micronized particles when aerosolized from the Novolizer®. The solvent / anti-solvent systems investigated and optimized for combination particles were water / EA, water / IPA, and water / IPA:EA 1:10 (w/w). IPA was found to be the optimum anti-solvent for producing combination particles of AS and IB with the smallest size. These combination particles showed uniform co-deposition during in vitro aerosol performance testing from the Novolizer®. Pilot molecular modeling studies in conjunction with the analysis of particle interactions using HINT provided an improved understanding of the possible interactions between AS and IB within a combination particle matrix.

Download or read book Controlled Pulmonary Drug Delivery written by Hugh D.C. Smyth and published by Springer Science & Business Media. This book was released on 2011-06-24 with total page 560 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
