Purpose To understand hydrolysis and alcoholysis of polyvinylpyrrolidone-co-vinylacetate (PVPVA) during formulation and storage, elucidate the reaction mechanism, establish an intrinsic kinetic model, and apply this model coupled with GastroPlus™ modeling to predict the amount of PVPVA degradation in vivo. Methods The experimental approach includes the detection of the polymer reaction by solution...
