In Vitro Release Testing (IVRT)

We are testing drug release in a fast and reliable way by using
in vitro release testing (IVRT) based on vertical diffusion cells
and synthetic membranes.




Drug release of the active pharmaceutical ingredient (API) from its formulation strongly depends on the composition of the drug product. We use IVRT for formulation optimization, quality control, generic drug approval and to prove product sameness after postapproval changes.
