Abstract
In one aspect, pharmaceutical compositions comprising dispersions of an acid-sensitive drug and a neutral dispersion polymer are disclosed. The acid-sensitive drug has improved chemical stability relative to dispersions of the drug and acidic polymers. In another aspect, pharmaceutical compositions of low-solubility drugs and amphiphilic, hydroxy-functional vinyl copolymers are disclosed.
