Intravenous infusion is a necessary mode of delivery for many pharmaceuticals currently on the market or undergoing clinical trials. The technique of prolonged intravenous delivery in conscious, free-moving animal models has broadened the opportunity to study and evaluate the safety and efficacy of these therapeutic products. For the first time, the collective sciences involved in the understanding of this mode of drug delivery are brought together in one publication.
Non-Clinical Vascular Infusion Technology, Volume I: The Science covers the scientific principles behind the delivery systems, from both physical and physiological standpoints. The book addresses body fluid dynamics, describes the scientific processes necessary to understand the various aspects of the physico-chemical issues relating to vascular infusion delivery, and discusses vascular infusion dynamics. It also considers all the essential elements of the preparation of a formulation intended for vascular delivery as well as assessment of compatibility of the formulation with the dosing apparatus. This volume, along with Volume II: The Techniques, provides a foundation of knowledge on infusion technology and its importance for safe clinical use of substances via this route of delivery.

"Good science and good welfare go hand in hand. Innovative science and technology can be used to improve animal welfare. Equally, the 3Rs (replacement, refinement and reduction of animals in research) can provide fresh insight and novel approaches to advance science. By sharing data, knowledge and experience on the science behind infusion models and the refinement of the techniques used, there is the potential to have a significant impact on the 3Rs.
Owen Green and Guy Healing have shown the importance of the 3Rs in infusion technology at international meetings and in producing this book. The book will enhance uptake of the latest science behind vascular delivery systems to get better data and help influence decisions around the most appropriate model. It will also contribute to preventing repetition of method development and optimising experiments to answer specific scientific questions with the least impact on animals.
As in other areas of science, the field of infusion technology is constantly evolving. This edition of Non-Clinical Vascular Infusion Technology reviews current developments in the field that will support scientists in putting the 3Rs into practice."
