Copley Scientific’s new white paper addresses issues in ‘Refining inhaled product testing’

14 December 2011; Nottingham, UK: Copley Scientific has published a new, freely available white paper that discusses ‘Refining inhaled product testing’. This timely review comes as the pharmaceutical industry maintains its drive towards greater efficiency, from faster time to market through to better manufacturing practice. It is against this backdrop that analytical tools are currently facing considerable scrutiny as to whether they provide relevant information and enable maximum productivity.

Inhaled product development is uniquely challenging but there is a desire to move towards a more knowledge-driven approach. Focusing on the core technique of cascade impaction, Mark Copley looks at how testing is being refined to support the aspiration of more efficient practice and the generation of better product understanding. A key goal is to achieve better in vitro –in vivo relationships, as well as reducing the burden of QC testing.

‘Refining inhaled product testing’ reviews current testing regimes and discusses ideas surrounding Abbreviated Impactor Measurement/Efficient Data Analysis, and the progress that has been made, summarising experimental work to date. Changes to nebulizer testing are given as an example of how some areas are already being revised, with more representative breath profiles and cooling for more accurate APSD measurement.
