  • Patent number: 8951564
    Abstract: The present invention relates to a galenic form comprising particles capable of specifically adsorbing the undesirable molecules present in the digestive tract, to the method for preparing same and to the use thereof in particular for producing a medicine intended for preventing or treating undesirable effects linked to an imbalance of the intestinal and/or colonic flora that can result for example from treatment with antibiotics.

  • Patent number: 8388984
    Abstract: Compositions which deliver adsorbents, alone or in combination with active drug “degrading molecules,” in a site-specific manner to the intestine, and which eliminate or at least lower the concentration of residual unwanted material within the intestine, and methods of treatment using the compositions, are disclosed. The compositions are ideally designed to specifically release the adsorbents in a programmed manner at a specific site of the intestinal tract. Programmed delivery prevents adsorbents from interfering with the normal absorption process of a given molecule after oral absorption, until it reaches the lower part of the small intestine. The compositions can be used to adsorb, and therefore remove, any residual drug, metabolite thereof, or bacterial toxin after oral or parenteral administration which would otherwise cause adverse effects in the lower intestine and/or colon.

  • Patent number: 8106000
    Abstract: Orally administrable, site-specific (colonic), particulate delivery systems including adsorbents are disclosed. When delivered specifically to the colon, they can remove various substances present in, or as they reach, the colon. Methods of treatment using the delivery systems, and methods of preparing the delivery systems, are also disclosed. The particulate delivery systems are based on adsorbent matrices encapsulated into and/or onto particles, which selectively deliver the adsorbents to the colon. Representative drug delivery devices include pectin beads, which can optionally be crosslinked with metal ions such as zinc and/or calcium. The delivery system protects the adsorbent and prevents its adsorbing effect in the upper gastro-intestinal (GI) tract. When the particles are made from pectin, and the beads are administered to the colon, specific pectinolytic enzymes in the colon degrade the pectin, allowing the adsorbent to be released and to be fully active.

  • Patent number: 8048413
    Abstract: Compositions which deliver adsorbents, alone or in combination with active drug “degrading molecules,” in a site-specific manner to the intestine, and which eliminate or at least lower the concentration of residual unwanted material within the intestine, are disclosed. Methods of treatment using the compositions are also disclosed. The material to be eliminated can include residual active antibiotics, metabolites, bacterial or other toxins, and drugs which cause side effects in the gastrointestinal tract. The adsorbents can be formulated in capsules, tablets or any acceptable pharmaceutical composition, and are ideally designed to specifically release the adsorbents in a programmed manner at a specific site of the intestinal tract. The programmed delivery prevents adsorbents from interfering with the normal absorption process of a given molecule after oral absorption, until it reaches the lower part of the small intestine.

  • Publication number: 20090047314
    Abstract: The invention relates to microencapsulation systems which are characterised in that they are developed from oily substances or sugars and in that they form an essentially organised assembly corresponding to stacks of crystalline structures. The inventive systems can be used for the microencapsulation of one or more substances which are of interest, such as therapeutically-active substances, or which can be used in cosmetics.

  • Patent number: 7485294
    Abstract: Forms of colonic delivery suited to be used orally and designed for colonic delivery of active ingredients selected from the group comprising enzymes capable of inactivating macrolide antibiotics and related compounds, enzymes capable of inactivating quinolones, and ?-lactamases.

  • Publication number: 20080317666
    Abstract: Drug delivery devices that are orally administered, and that release active ingredients in the colon, are disclosed. In one embodiment, the active ingredients are those that inactivate antibiotics, such as macrolides, quinolones and beta-lactam containing antibiotics. One example of a suitable active agent is an enzyme such as beta-lactamases. In another embodiment, the active agents are those that specifically treat colonic disorders, such as Chrohn's Disease, irritable bowel syndrome, ulcerative colitis, colorectal cancer or constipation. The drug delivery devices are in the form of beads of pectin, crosslinked with calcium and reticulated with polyethyleneimine. The high crosslink density of the polyethyleneimine is believed to stabilize the pectin beads for a sufficient amount of time such that a substantial amount of the active ingredients can be administered directly to the colon.
