  • Publication number: 20210161827
    Abstract: Described herein is a composition comprising microparticles of one or more taste-masked active pharmaceutical ingredient(s), rapidly-dispersing microgranules, and other optional, pharmaceutically acceptable excipients. The microparticles (crystals, granules, beads or pellets containing the active) are coated with a taste-masking membrane comprising a water-insoluble polymer and one or more gastrosoluble inorganic or organic pore-formers (practically insoluble in water and saliva, but soluble in an acidic buffer), exhibit acceptable taste-masking when placed in the oral cavity and provide rapid, substantially-complete release of the dose on entry into the stomach.

  • Patent number: 10952971
    Abstract: There is provided a method for preparing an orally disintegrating tablet (ODT) composition comprising microparticles of one or more taste-masked active pharmaceutical ingredient(s), rapidly-dispersing microgranules, and other optional, pharmaceutically acceptable excipients wherein the ODT disintegrates on contact with saliva in the buccal cavity forming a smooth, easy-to-swallow suspension. Furthermore, the microparticles (crystals, granules, beads or pellets containing the active), coated with a taste-masking membrane comprising a water-insoluble polymer and one or more gastrosoluble inorganic or organic pore-formers (practically insoluble in water and saliva, but soluble in an acidic buffer), exhibit acceptable taste-masking when placed in the oral cavity and provide rapid, substantially-complete release of the dose on entry into the stomach.

  • Patent number: 9730896
    Abstract: A tablet that rapidly disintegrates in the oral cavity comprising a compressed blend of rapidly dispersing microgranules prepared by granulating a sugar alcohol or a saccharide or a mixture thereof having an average particle size less than about 30 microns and a disintegrant, and a taste-masked microcapsule containing at least one drag, the microcapsule being prepared by granulating a pharmaceutically acceptable formulation comprising at least one drug in a therapeutically effective amount and at least one polymeric binder that improves resilience of the microgranules, wet milling the granulated mass, and microencapsulating the milled granules to provide microcapsules.
