  • Method for producing a controlled release preparation
    Publication number: 20060159755
    Abstract: The invention concerns a method for producing a controlled-release pharmaceutical preparation with a particle-containing coating, the coating being derived from an aqueous dispersion of a film-forming water insoluble polymer and a water soluble pore-forming agent. By suspending, instead of dissolving the pore-forming agent, the resulting coating will contain particles of pore-formers with a predetermined size that creates, when disintegrated or dissolved in the body fluid, canals or a network of pores through the polymer film.

  • Method for producing a controlled-release preparation
    Patent number: 6974591
    Abstract: The invention concerns a method for producing a controlled-release pharmaceutical preparation with a particle-containing coating, the coating being derived from an aqueous dispersion of a film-forming water insoluble polymer and a water soluble pore-forming agent. By suspending, instead of dissolving the pore-forming agent, the resulting coating will contain particles of the pore-formers with a predetermined size that creates, when disintegrated or dissolved in the body fluid, canals or a network of pores through the polymer film. Due to this network, the film will get a good mechanical stability and are left intact after the release of the drug.

  • Method for releasing nanosized particles of an active substance from a diffusion-controlled pharmaceutical composition for oral use
    Publication number: 20030215513
    Abstract: The present invention relates to a method for releasing an active substance from a composition. The active substance is either substantially water-insoluble and/or immobilised on or in nanosized particles. A diffusion gradient is established between the inside and the outside of the composition, which allows the transport of a nanosuspension of the active substance through the pores of the membrane.
