A Guide to Particulate Science in Pharmaceutical Product Development (Paperback)

The pharmaceutical applications of powder technology have long been recognized. Yet while many books focus on aspects of powder formation and behavior, there are few texts that explore the power of particulate science in the design, manufacture, and control of quality medicines. This revision discusses key principles and practical applications. The authors cover particulate material, its form and production, sampling from bodies of powder, particle size descriptors and statistics, behavior of particles and powder, instrumental analysis, particle size measurement and synergy of adopted techniques, and in vitro and in vivo performance criteria. Case studies are included in this new edition.

This fully revised edition:

• Provides an essential account of particulate science including several new chapters on multicomponent particles, regulatory considerations and product development
• Presents a variety of topics ranging from the quality of published data on particle size in pharmaceuticals to the future of crystal engineering
• Reviews methods of particle measurement and their importance for specific applications
• Discusses misconceptions and misunderstandings of particulate science together with lessons from other industries

Dr Margaret Louey is a pharmaceutical scientist with extensive experience in drug development and global health initiatives. She earned a Ph.D. from Monash University in Melbourne, Australia (2000), and then completed a post-doctoral fellowship at the University of North Carolina in Chapel Hill. Margaret entered the pharmaceutical industry and worked at GlaxoSmithKline for 15 years, primarily in product development of respiratory products. During this time, her interest evolved to increasing access to medicines in low- and middle-income countries. Margaret transitioned to the non-profit sector and joined the Clinton Health Access Initiative in 2018, where she has supported public-private partnerships to accelerate product development and regulatory submissions for high-priority pediatric products for the treatment and prevention of HIV and tuberculosis in low- and middle-income countries.

Dr Timothy “Timm” Crowder, Ph.D., is a pharmaceutical scientist and entrepreneur with deep expertise in particulate science and drug delivery, particularly in inhalation technologies. He earned his Ph.D. from the University of North Carolina at Chapel Hill, where his research focused on the design and development of innovative drug delivery systems. This work sparked a lifelong interest in the complex interplay between particle engineering, device design, and clinical outcomes.

Timm’s career has spanned both industry and entrepreneurial ventures, with a particular focus on transforming cutting-edge research into practical, patient-centric therapies. As a co-founder of Oriel Therapeutics, Timm helped pioneer new approaches to dry powder inhaler technology. He went on to hold leadership roles across both large pharmaceutical companies and biotech startups, where he applied his expertise to advance inhaled therapies for respiratory diseases, rare conditions, and systemic delivery.

Throughout his career, Timm has remained passionate about bridging the gap between fundamental science and real-world product development. His work has encompassed everything from dry powder vaccine formulations to advanced inhaler technologies, always with an emphasis on delivering therapies that improve patient outcomes. In addition to his industry contributions, Timm has maintained a strong connection to academic research and training, co-authoring key publications on pharmaceutical particulate science and mentoring the next generation of scientists and innovators in the field.
