Evaluation of Human Regional Bioavailability to Assess Whether Modified Release Development is Feasible

Many modified release (MR) oral formulations rely on bioavailability from the distal regions of the gastrointestinal (GI) tract (i.e. the ileum and colon). Therefore, by assessing the bioavailability of a drug following delivery to the distal intestines, it is possible to determine whether MR formulation development is achievable.
