Abstract: The present invention relates to solid pharmaceutical compositions comprising the phosphatidylinositol 3-kinase inhibitor compound 4-(trifluoromethyl)-5-(2,6-dimorpholinopyrimidin-4-yl)pyridin-2-amine or a pharmaceutically acceptable salt thereof, sodium stearyl fumarate, and optionally at least one additional pharmaceutically acceptable carrier. The present invention also relates to the processes for their preparation and to their use as medicaments for the treatment of cancer.

Abstract: There are described solid compositions or examining drug solubility comprising bile salts and phospholipids, optionally containing buffer components suitable for preparation of intestinal media that simulate the composition of the intestinal fluids in fasted and fed states.

Abstract: A tablet system for prolonged floating in or on gastric fluid for releasing therein pharmaceutically active substances in an alternate succession of substance release and no-release periods is made up of a multilayered core placed in a cup-shaped envelope. The core is made up of release layers and no-release layers devoid of pharmaceutically active substance, superposed in alternate succession. The cup-shaped envelope covers bottom and side surfaces of the core while leaving exposed an upper surface of the core. The cup-shaped envelope provides for buoyancy by being formed of a compression-sintered mixture comprising hydrophobic material and inert powdered filler. The hydrophobic material is composed of fatty and/or waxy material capable of being sintered by compression and whose bulk density is lower than gastric fluid density. The powdered filler has a loose powder density that is lower than gastric fluid density.

Abstract: There is described dry compositions comprising lipophilic compounds associated with low viscosity grades of water insoluble polymer and optionally hydrophilic agent/s associated either as monomolecular or amorphous complexes. There is also described a method of preparing said lipophilic polymer complexes from a solution or homogeneous dispersion employing either water miscible or immiscible organic solvents. The lipophilic polymer complex is precipitated from the solution comprising a water miscible solvent by dilution with water, separating out the precipitated complex, washing, drying and conversion to oral and topical dosage forms. The lipophilic polymer complex may also be prepared by solvent removal involving spray drying or vacuum drying under elevated temperatures using either water miscible or water immiscible solvents. The compositions are characterised by improved dissolution and solubility of the associated compound in aqueous medium.
