Pharmaceutical Process Development


Book Description

Pharmaceutical process research and development is an exacting, multidisciplinary effort but a somewhat neglected discipline in the chemical curriculum. This book presents an overview of the many facets of process development and how recent advances in synthetic organic chemistry, process technology and chemical engineering have impacted on the manufacture of pharmaceuticals. In 15 concise chapters the book covers such diverse subjects as route selection and economics, the interface with medicinal chemistry, the impact of green chemistry, safety, the crucial role of physical organic measurements in gaining a deeper understanding of chemical behaviour, the role of the analyst, new tools and innovations in reactor design, purification and separation, solid state chemistry and its role in formulation. The book ends with an assessment of future trends and challenges. The book provides a valuable overview of: both early and late stage chemical development, how safe and scaleable synthetic routes are designed, selected and developed, the importance of the chemical engineering, analytical and manufacturing interfaces, the key enabling technologies, including catalysis and biocatalysis, the importance of the green chemical perspective and solid form issues. The book, written and edited by experts in the field, is a contemporary, holistic treatise, with a logical sequence for process development and mini-case histories within the chapters to bring alive different aspects of the process. It is completely pharmaceutical themed, encompassing all essential aspects, from route and reagent selection to manufacture of the active compound. The book is aimed at both graduates and postgraduates interested in a career in the pharmaceutical industry. It informs them about the breadth of the work carried out in chemical research and development departments, and gives them a feel for the challenges involved in the job. The book is also of value to academics who often understand the drug discovery arena, but have far less appreciation of the drug development area, and are thus unable to advise their students about the relative merits of careers in chemical development versus discovery.




The Management of Chemical Process Development in the Pharmaceutical Industry


Book Description

This book illustrates practical considerations through many examples of the successful direction and integration of the activities of chemists, analysts, chemical engineers, and biologists, as well as safety, regulatory, and environmental professionals in productive teams. Moreover, this reference provides guidance on: Directing and carrying out specific tasks and courses of action Making and communicating clear and achievable decisions Solving problems on the spot Managing the administrative aspects of chemical process development The author, Dr. Derek Walker, has directed chemical process development work for four decades, combining firsthand chemical synthesis experience with many other disciplines needed to create chemical processes. You will benefit from his advice and unique insights into: Understanding the workings of matrix organizations Defining missions and creating action plans Developing interdisciplinary approaches to problem solving Holding review meetings, revising goals, and motivating staff Prioritizing programs and responses to emergencies In addition, you'll learn how successful chemists, in collaboration with other disciplines, define the best (green) chemistry for process scale-up, including accommodating FDA requirements in the last process steps and addressing safety and environmental matters early in their work. Case studies provide incisive perspective on these issues. A chapter on recognizing and patenting intellectual property emphasizes the importance of comprehensive literature surveys and understanding invention. A chapter on the future challenges you to think beyond narrow constraints and explore new horizons.




Principles of Process Research and Chemical Development in the Pharmaceutical Industry


Book Description

Dr. Oljan Repic clearly explains the goals and basic principles of chemical development. He explores the crucial aspects of a new process that must be considered when scaling up a research synthesis to industrial levels. And, with the help of many case studies and vignettes, he delineates each phase of the development process. Key topics include qualities of an ideal process, techniques for minimizing impurities, criteria for cost-effective synthesis of enantiopure compounds by resolutions, asymmetric synthesis and the "chiral pool" strategy, synthesis for labeling substances with hydrogen or carbon isotopes, and new drug registration requirements. This book is an invaluable reference for professionals as well as an important source of guidance and inspiration for young chemists considering entering the field.

Industrial Chemical Process Analysis and Design


Book Description

Industrial Chemical Process Analysis and Design uses chemical engineering principles to explain the transformation of basic raw materials into major chemical products. The book discusses traditional processes to create products like nitric acid, sulphuric acid, ammonia, and methanol, as well as more novel products like bioethanol and biodiesel. Historical perspectives show how current chemical processes have developed over years or even decades to improve their yields, from the discovery of the chemical reaction or physico-chemical principle to the industrial process needed to yield commercial quantities. Starting with an introduction to process design, optimization, and safety, Martin then provides stand-alone chapters—in a case study fashion—for commercially important chemical production processes. Computational software tools like MATLAB®, Excel, and Chemcad are used throughout to aid process analysis. - Integrates principles of chemical engineering, unit operations, and chemical reactor engineering to understand process synthesis and analysis - Combines traditional computation and modern software tools to compare different solutions for the same problem - Includes historical perspectives and traces the improving efficiencies of commercially important chemical production processes - Features worked examples and end-of-chapter problems with solutions to show the application of concepts discussed in the text
