IVIVC

Better In Vitro – In Vivo Correlation (IVIVC) has long been an industry aim. This is particularly difficult in the case of inhaled and nasal products because of the complications involved in precisely correlating drug deposition behaviour with clinical efficacy, the impact of patient-to-patient variability and the complex interaction between formulation and device.
One strategy for improving the significance of cascade impaction data is to modify the test set-up in order to mimic the in vivo drug delivery process more closely.
