This present invention is concerned with novel solid dispersion pharmaceutical compositions for preparation of composition which is comprised of a compound with poor water solubility (a weakly basic, neutral and/or non-ionizable, or a weakly acidic compound), water-soluble polymer(s), pH-sensitive polymer(s) (either enteric polymer or gastric-soluble polymer that is soluble at gastric fluid and insoluble at intestine pH range such as Eudragit E), and/or pharmaceutical acceptable surfactant(s) that would improve the solubility/dissolution of the compound in aqueous media of both low and neutral pHs and provide a relative pH-independent dissolution profile.
