Pfizer has endorsed a blister packaging inspection device, Visionscan, made by Sepha Ltd, following several months of trials.
Scientists on Pfizer's Process Analytical Technologies (PAT) team validated Visionscan's test cycle which is capable of non-destructively assessing blister integrity for multiple sizes, shapes, cavity configurations and materials of construction.
The test is relatively fast (about 1 minute per test cycle), empirical, and provides pass/fail results eliminating any need for human-visual analysis of samples and associated subjectivity.
Pfizer, along with a number of other global pharmaceutical multinationals, are moving away from out-dated, destructive inspection methods such as blue dye.
