Pharmaceutical compositions and stable nano-suspensions comprising mifepristone and at least one pharmaceutically acceptable excipient, which exhibit enhanced bioavailability compared to the currently marketed or commercially available formulations. Manufacturing process and methods of use are also provided. The pharmaceutical compositions are used for prevention, treatment or prophylaxis of disorders in human patients in need thereof. Oral pharmaceutical compositions of mifepristone, methods for their administration, processes for their production, and use of these compositions are described for the treatment of diseases for which mifepristone is indicated.

Described herein are compositions comprising particles of poorly soluble drugs encapsulated by stabilizers. Further described are pharmaceutical compositions comprising such encapsulated compositions. Also described are methods of making such encapsulated particle compositions, and methods of making the corresponding pharmaceutical compositions. The encapsulated particle compositions described herein allow poorly soluble drugs to be administered with good bioavailability by routes that are non-invasive to patients, such as by oral administration.

The invention relates to immobilized or encapsulated enzyme and/or cells to lower bile acids and cholesterol. The invention also relates to methods of quantitatively measuring bile acids. The invention provides a composition for decreasing the amount of a target compound in the gastrointestinal tract of an animal, comprising: a) a biologically active agent which decreases the amount of the target compound; b) a retainer for retaining the biologically active agent by contacting the agent to limit movement of the agent; and c) a carrier.

An aqueous liquid suspension containing a coated drug-ion exchange resin complex comprising a core composed of an amphetamine complexed with a pharmaceutically acceptable ion-exchange resin and an uncoated amphetamine-ion exchange resin complex is provided. The coated amphetamine-ion exchange resin complex is in admixture with a polymer to form a matrix. Methods of making the coated complex and the liquid suspension are described.

Provided are methods of treating diarrhea, particularly malabsorption diarrhea, in neonatal, young and adult non-human animals, in which the diarrhea results from infection of the animals by Salmonella spp., such as Salmonella typhimurium, with a therapeutically effective amount of a proanthocyanidin polymer from Croton lechleri, in either enteric or non-enteric form.

Compositions providing a once-a-night dose of oxybate are provided. The compositions containing bilayer-coated oxybate anion exchange resin complex multiparticulates provide modified release of the oxybate for 5 to 8 hours post-dosing. Also provided are methods of treating patients in need thereof with pharmaceutical compositions containing the oxybateanion exchange resin complex.

Described herein are compositions comprising particles of poorly soluble drugs encapsulated by stabilizers. Further described are pharmaceutical compositions comprising such encapsulated compositions. Also described are methods of making such encapsulated particle compositions, and methods of making the corresponding pharmaceutical compositions. The encapsulated particle compositions described herein allow poorly soluble drugs to be administered with good bioavailability by routes that are non-invasive to patients, such as by oral administration.

A particulate, barrier coated drug-anion exchange resin complex comprising a core composed of an acidic drug complexed with a pharmaceutically acceptable ion-exchange resin is provided. The barrier coating contains a polyvinyl acetate polymer and a plasticizer. Methods of making and products containing this coated complex are described.

The invention relates to a process for coating a solid, water-insoluble particulate matter, with a metal oxide comprising: (a) contacting the solid, water-insoluble particulate matter with an ionic additive and an aqueous medium to obtain a dispersion of said particulate matter having positive charges on its surface; (b) subjecting the particulate matter to a coating procedure comprising precipitating a metal oxide salt onto the surface of the particulate matter to form a metal oxide layer thereon to thereby obtain particulate matter coated by a metal oxide coating layer; (c) repeating step (b) at least 4 more times; and (d) aging said coating layer. The invention further relates to particles comprising a particulate matter coated by a metal oxide layer, to a use of the particles for topical administration, and to a method for preventing, reducing, or eliminating pests at a locus, using the particles.

An aqueous dispersion of particles comprising a resin having at least one repeating unit of formula I, II and/or III and which is obtainable by contacting in a liquid comprising water, a compound A comprising at least 2 functional groups selected from the group of functional groups XC(O)CHR1-C(O)R2, XC(O)CCR2; or XC(O)CR1=CR2-NR11R12, the functional groups are linked by a linking group comprising a polyester, polyether, polyolefin, polydimethylsiloxane or polycarbonate chain with a compound B comprising at least two NH.sub.2, NH.sub.3.sup.+ or NCO, wherein X, R1, R2, R3, R11 and R12 have the same meaning as that defined in the claims and w. The invention also includes a method of producing the aqueous dispersion. ##STR00001##
