A practical and science-based approach for addressing
toxicological concerns related to leachables and extractables
associated with inhalation drug products
Packaging and device components of Orally Inhaled and Nasal Drug
Products (OINDP)--such as metered dose inhalers, dry powder
inhalers, and nasal sprays--pose potential safety risks from
leachables and extractables, chemicals that can be released or
migrate from these components into the drug product. Addressing the
concepts, background, historical use, and development of safety
thresholds and their utility for qualifying leachables and
extractables in OINDP, the Leachables and Extractables Handbook
takes a practical approach to familiarize readers with the recent
recommendations for safety and risk assessment established through
a joint effort of scientists from the FDA, academia, and industry.
Coverage includes best practices for the chemical evaluation and
management of leachables and extractables throughout the
pharmaceutical product life cycle, as well as:
* Guidance for pharmaceutical professionals to qualify and
risk-assess container closure system leachables and extractables in
drug products
* Principles for defining toxicological safety thresholds that are
applicable to OINDP and potentially applicable to other drug
products
* Regulatory perspectives, along with an appendix of key terms and
definitions, case studies, and sample protocols
Analytical chemists, packaging and device engineers, formulation
development scientists, component suppliers, regulatory affairs
specialists, and toxicologists will all benefit from the wealth of
information offered in this important text.

information across both toxicology and pharmaceutical
analysis/development, it is probably most useful for practicing
toxicologists or chemists, providing both a detailed reference to
dip into and a means of better understanding the requirements and
contributions of colleagues working in the other
discipline." (British Toxicology Society, 1 July

"However, the book is extremely well written and is a
compelling read. The book accomplishes its goal to provide a
state of the art review with respect to mercury . . . The book
serves as an excellent educational resource."
