  • Patent number: 11285104
    Abstract: A sustained-release formulation of 5-fluorouracil (5-FU) providing a polymeric coating in a nanosuspension comprising sodium alginate and carrageenan for oral administration. The nanosuspension forms an insoluble sedimenting gel in the low pH environment of the stomach to speed gastric emptying. The sedimented insoluble gel becomes soluble in the pH environment of the small intestine and is transported to the colon where 5-FU is released at a predictable rate. The targeted delivery to the colon inhibits loss of 5-FU in the gastrointestinal tract and increases 5-FU exposure to cancerous cells in the colon.

  • Patent number: 9011926
    Abstract: In a production process of granules containing a biologically active substance, variation in the elution profile of the biologically active substance is reduced by heating the temperature of granules to about 50° C. or higher and maintaining the temperature for about 1 minute or longer. By setting the spray speed to about 90 mg/min or more per 1 g of cores when a spray agent for a primary agent containing the biologically active substance is sprayed while spraying a binding liquid to the cores and setting the total feeding weight per unit area for a centrifugal fluidized bed coating granulation machine to about 1.5 g/cm2 or more, the variation in the elution profile of the biologically active substance from the granules is reduced.

  • Patent number: 9005658
    Abstract: A pharmaceutical pellet is provided, comprising a spherical core containing the active substance with a smooth surface and a coating on the core, which controls pH-independent release of the active substance. With a pellet of this kind, the release of the active substance may follow a profile with a lag-phase from 60 minutes to 840 minutes, where during the lag-phase a proportion of 5 wt. % or less of the active substance is released. Furthermore, the active substance may be released from the pellet with a profile such that, after the lag-phase, the release of the active substance is between 3 and 25 wt. % per hour. The active substance is a metoprolol salt.

  • Publication number: 20150086623
    Abstract: A controlled-release pharmaceutical composition including first and second groups of microparticles, each of the microparticles including a core including tamsulosin or pharmaceutically acceptable salts thereof, a controlled-release polymer coating layer formed on the core, and an enteric polymer outer layer formed on the controlled-release polymer coating layer, wherein the average thickness of the controlled-release polymer coating layer is different in each of the first and second groups of microparticles, and an oral formulation including the same, are provided. This pharmaceutical composition can easily control the extent of release of an active ingredient depending on changes in pH in the intestinal tract and the release pattern of the active ingredient in the small intestine, thus preventing the active ingredient from being rapidly transferred into the blood to thereby minimize side-effects, and maintaining the effective blood concentration of the active ingredient for a predetermined period of time.

  • Publication number: 20150072858
    Abstract: The present disclosure is directed to cellulose ether compositions for film-forming coating applications. A coating composition is provided which contains an aqueous solution of either a very low viscosity cellulose ether or a low-hydroxypropyl cellulose ether, the coating composition having low color. The low viscosity of the cellulose ether component enables the coating composition to contain a high concentration of cellulose ether. Provision of these high concentration cellulose ether coating solutions improves production efficiency by reducing the time required to coat a substrate.
