  • Publication number: 20030129235
    Abstract: An oral solid dosage form includes a therapeutically effective amount of an NSAID and a proton pump inhibitor in an amount effective to inhibit or prevent gastrointestinal side effects normally associated with the NSAID. Also disclosed is a method of treating a human patient in need of antiinflammatory, analgesic and/or antipyretic therapy, comprising orally administering to the patient an oral pharmaceutical dosage form which includes a therapeutically effective amount of an NSAID and an amount of a proton pump inhibitor effective to substantially inhibit gastrointestinal side effects of the NSAID. The invention is further related to a method of prophylactically treating a human patient who is on a therapy known to have significant gastrointestinal side effects or is about to begin such a therapy, via concurrent administration of an NSAID and a proton pump inhibitor in a combination (single) oral dosage form.

  • Patent number: 6368625
    Abstract: A dosage form which rapidly disintegrates in the mouth and forms a viscous slurry of either microcapsules or a powder is described. The rapidly disintegrating dosage form is meant for direct oral administration by placing a tablet or capsule in the mouth of a patient. Upon disintegration, a viscosity of the resulting slurry increases so as to form an organoleptically pleasant viscous material which retards the spread of insoluble materials including the drug.
