  • Publication number: 20100178353
    Abstract: The invention provides a composition useful for making oral dosage forms capable of dissolving in the mouth in less than 40 seconds without the need for a conventional super disintegrant and having a friability of less than 1%; wherein the composition includes liquiflash particles and an excipient mass. A preferred excipient mass according to the invention contains a directly compressible inorganic salt; a cellulose derivative or a combination of a directly compressible inorganic salt and a cellulose derivative. Preferably, the liquiflash particles and the excipient mass are combined in proportions such that the active ingredient remains substantially within the microspheres when the composition is compressed to obtain a dosage form having a hardness of 20 to 50 N. The compositions of the invention allow for the fabrication of oral dosages having improved hardness and friability.

  • Patent number: 7700131
    Abstract: Powders having contact biocidal properties comprise a polysaccharide carrying atomic/metallic silver. The preferred polysaccharide is chitin, although other polysaccharides including chitosan, carboxymethyl celluloses and carrageenans can be used. The chitin may be obtained from deproteinated crustacean shells without demineralisation, thus being admixed with calcium carbonate and other naturally occurring minerals present in the shells, and may be enzyme deacetylated. The powders of the invention can be used as biocidal dusting powders, formulated into pastes, gels, hydrogels, creams, foams and aerosol sprays for pharmaceutical applications, or dissolved to form solutions for coating substrates such as skin, fabrics, glass, leather and paper to give a bactericidal surface. A particular application of such a solution is as a protective, post-wash treatment for workwear in a laundering process.

The invention aims at providing a novel pharmaceutical with time-dependent and pH-dependent release mechanism, enabling: a) the latent period preceding the release of the active principle in the stomach; b) the pH triggering the release of the active principle in the intestine; c) the release speed of the active principle. This is achieved through the use of coated microparticles made from particles of active principle each coated with two coating films A and B. A comprises: film-forming (co)polymer (A1) insoluble in fluids of the gastrointestinal tract; ethylcellulose (co)polymer (A2) soluble in fluids of the gastrointestinal tract; plasticizing polyvinylpyrrolidone (A3); castor oil/optionally a surfactant and/or magnesium stearate lubricant (A4). B comprises a hydrophilic polymer (B1) bearing ionized groups with neutral pH (EUDRAGIT® L100-55) and a hydrophobic compound (B2) (LUBRITAB®).

  • Patent number: 7576067
    Abstract: Delayed release oral pharmaceutical formulations and methods for enhanced intestinal drug absorption. The formulation comprises a first population of carrier particles comprising a drug and a penetration enhancer which are released at a first location in the intestine, and a second population of carrier particles comprising a penetration enhancer and a delayed release coating or matrix. This penetration enhancer is released at a second location in the intestine downstream from the first location and enhances absorption of the drug when it reaches the second location.
