In vitro drug dissolution test facilitates design, development, and quality assurance of solid (oral) products. During product development dissolution tests are used to characterize impact of formulation variables on drug release and to optimize formulations to achieve a target drug release profile (assuming the in vitro test is predictive of in vivo drug release). Every manufactured batch must meet pre-set specifications prior to being released for distribution. Certain “minor” post-approval changes in the manufacturing process and/or formulation may be justified by demonstrating equivalent in vitro dissolution profiles1. For certain “major” post-approval changes the FDA may grant requests for waiver of in vivo bioequivalence studies when a sponsor demonstrates acceptable predictive ability of the selected in vitro test (i.e., availability of an validated in vitro to in vivo correlation -IVIVC)2.
