Patent application numberDescriptionPublished
20080199527Enteric Coated Azithromycin Multiparticulates - A pharmaceutical composition is disclosed which comprises multiparticulates wherein said multiparticulates further comprise an azithromycin core and an enteric coating disposed upon said azithromycin core.08-21-2008
20080262107Pharmaceutical Compositions With Enhanced Performance - Disclosed are polymers of hydroxypropyl methyl cellulose acetate succinate (HPMCAS) and hydroxypropyl methyl cellulose acetate (HPMCA) with unique degrees of substitution of hydroxypropoxy, methoxy, acetyl, and succinoyl groups. When used in making compositions comprising a low-solubility drug and such polymers, the polymers provide enhanced aqueous concentrations and/or improved physical stability.10-23-2008
20080292707Pharmaceutical Compositions of Adsorbates of Amorphous Drug - Pharmaceutical compositions comprise a low-solubility drug adsorbed onto a high surface area substrate to form an adsorbate. The compositions in some embodiments include a concentration-enhancing polymer.11-27-2008
20080293801Solid Amorphous Dispersions of An Mtp Inhibitor For Treatment of Obesity - A composition comprises a solid amorphous dispersion comprising (S)—N-{2-[benzyl(methyl)amino]-2-oxo-1-phenylethyl}-methyl-5-[4′-(trifluoromethyl)[1,1′-biphenyl]-2-carboxamido]-1H-indole-2-carboxamide and a polymer.11-27-2008
20080299188CONTROLLED RELEASE DOSAGE FORMS COMBINING IMMEDIATE RELEASE AND SUSTAINTED RELEASE OF LOW-SOLUBILITY DRUG - A controlled release dosage form comprises an immediate release portion and an enteric coated sustained release core.12-04-2008
20080317851IMMEDIATE RELEASE DOSAGE FORMS CONTAINING SOLID DRUG DISBURSIONS - High loading immediate release dosage forms containing at least 30 wt % of a solid drug dispersion, at least 5 wt % of a disintegrant and a porosigen are disclosed that exhibit excellent strength and aqueous solubility.12-25-2008
20090011024Pharmaceutical compositions of dispersions of amorphous drugs mixed with polymers - A pharmaceutical composition comprises a dispersion comprising a low-solubility drug and a matrix combined with a concentration-enhancing polymer. At least a major portion of the drug is amorphous in the dispersion. The compositions improve the stability of the drug in the dispersion, and/or the concentration of drug in a use environment.01-08-2009
20090142404PHARMACEUTICAL DOSAGE FORMS COMPRISING A LOW-SOLUBILITY DRUG AND A POLYMER - A dosage form comprises a low-solubility drug, and a precipitation-inhibiting polymer. The drug is in a solubility-improved form and in the form of particles at least partially coated with the precipitation-inhibiting polymer. Exemplified low-solubility drugs are ziprasidone and sildenafil. Exemplified precipitation-inhibiting polymer is HPMCAS.06-04-2009
20100215747NANOPARTICLES COMPRISING IONIZABLE, POORLY WATER SOLUBLE CELLULOSIC POLYMERS - A pharmaceutical composition comprises nanoparticles comprising ionizable, poorly water soluble cellulosic polymers.08-26-2010
