Abstract: The present invention relates to iodine demand disinfectants. It relates in particular to a process for preparing a polyiodide-resin for use as an iodine demand disinfectant wherein a porous strong base anion exchange resin in a salt form, is contacted with a material capable of donating a member absorbable by the resin so as to convert the resin to the polyiodide-resin. The adsorbable member is selected from the group comprising I2 and polyiodide ion having a valence of −1. The process is characterized in that conversion of the anion exchange resin to the polyiodide-resin is effected at elevated temperature and elevated pressure, the elevated temperature being 100 degrees C. or higher, the elevated pressure being greater than atmospheric pressure. The present invention also relates to disinfectant substance comprising an iodine (impregnated) resin as produced by the above process.

Abstract: This invention relates to the formulation of oral liquid products of quinolones or derivatives thereof using ion exchange resins, such as methacrylic acid polymer crosslinked with divinylbenzene, as the carrier, thereby eliminating the extreme bitterness of the quinolones oral liquid formulation.

Abstract: A dosage form is described that gives an extended release of active ingredients using unloaded ion exchange resins, that does not require the manufacture of a resinate.

Abstract: There are provided an adsorbent which can effectively adsorb and remove endogenous cannabinoid in fluid, and a process for removing endogenous cannabinoid in fluid by means of the adsorbent. The adsorbent of endogenous cannabinoid is obtained by fixing a compound having a log P value (P indicating distribution coefficient in octanol-water system) of at least 3.50 on a water-insoluble carrier. Endogenous cannabinoid in fluid can be adsorbed and removed in an effective manner by contacting the adsorbent of endogenous cannabinoid with fluid containing endogenous cannabinoid.

Abstract: A dosage form comprising a resin/resinate combination is described. Said dosage form allows optimization of the release rate profile of active ingredients.

Abstract: The present invention relates to a method for sequestering bile acids in a patient and to particular polymers for use in the method. The method comprises administering a therapeutically effective amount of a guanidinium moiety-containing polymer composition to a mammal, such as a human, whereby bile acids are sequestered. The polymers of the invention comprise guanidinium moieties and optionally, additional substituents such as a hydrophobic group, a quaternary ammonium-containing group or a combination thereof.

Abstract: A method for treating pathogenic toxins in a mammal, such as a human, comprising treating the mammal with a therapeutically effective amount of a polymer comprising a cationic group attached to the polymer backbone. The polymer can be a homopolymer or a copolymer. In one embodiment, the polymer is a copolymer comprising a monomer having a pendant ammonium group and a hydrophobic monomer.
