Evaluation of hypromellose acetate succinate (HPMCAS) as a carrier in solid dispersions.
TL;DR: Hypromellose acetate succinate showed the highest drug dissolution level from its solid dispersion in a dissolution study using a buffer of pH 6.8, and the inhibitory effect of HPMCAS on recrystallization of NP from a supersaturated solution was the greatest among all the polymers examined.
