With Pion’s MacroFLUX™ device, you can reliably test and rank the absorption potential of formulations and finished drug products in vitro. This is accomplished using a standard USP dissolution set-up coupled with an absorption chamber along with fiber optic UV detection and can greatly enhance in vivo prediction.
In many cases, dissolution experiments alone cannot predict the in vivo response of drug products due to the complicated interplay of solubility and permeability in complex media. By introducing a stirred absorption chamber into familiar dissolution apparatus, Pion’s MacroFLUX allows you to extend the utility of in situ concentration monitoring and reach the required data density for accurate assessment of transmembrane FLUX.
Pion’s MacroFLUX™ device improves the assessment of absorption potential, providing for:
In a case study using MacroFLUX™ to compare the dissolution and flux results of an innovator and a generic product, the in vitro result (showing the generic at 71% of the flux of the innovator) revealed excellent correlation with the in vivo data (at 72%) taken from bioequivalence studies .
