Exploring a Bioequivalence Failure for Silodosin Products Due to Disintegrant Excipients
Some years ago, excipients were considered inert substances irrelevant in the absorption process. However, years of study have demonstrated that this belief is not always true.
Approaches of formulation bridging in support of orally administered drug product development
As a drug advances through the late stages of clinical development, formulation changes are common to meet clinical, manufacturing, and/or business needs.
Deciphering the immuno-pathological role of FLT, and evaluation of a novel dual inhibitor of topoisomerases and mutant-FLT3 for treating leukemia
