  • Patent number: 6596312
    Abstract: The present invention provides a method for preparing a spray-dried, compressible granular formulation for preparing pharmaceutical tablets in which essentially water-insoluble, acidic, amphoteric, and basic pharmaceutically active agents are converted to more water-soluble salts which are granulated with hydrolyzed cellulose, drug-containing slurries, the resulting granulations, capsules containing granulations, and pharmaceutical tablets compressed from such granules. In these formulations there is employed from 1% to 85% by weight of the pharmaceutically active agent and its salt form, from 5% to 99% of hydrolyzed cellulose, based on the dry weight of the granulation, and optionally, conventional granulation and/or tableting additives such as surfactants, disintegrants, and antiadherents/flow aids. Said tablets have significantly increased dissolution of the pharmaceutically active agent at the pH of the gastrointestinal tract in comparison with the unconverted free pharmaceutically active agent.

  • Patent number: 6588180
    Abstract: A blister pack which confines the movement a dosage form in order to resist damage thereto during handling and transportation while permitting removal of the intact dosage form, and apparatus and methods for the same. In particular, the invention provides a blister pack wherein the blister includes a protruding region between the opening and the base, thereby producing a constricted area or “neck” in the blister. In a preferred embodiment, the protruding region comprises an inwardly directed annulus formed in the blister wall. Accordingly, vertical movement of the dosage form is confined as a result of the protruding region, thereby reducing the likelihood of damage to the dosage form caused by agitation of the blister pack. The invention is particularly useful in packaging frangible pharmaceutical dosage forms formed in situ within the blister, such as freeze dried dosage forms and rapidly dissolving oral dosage forms.

  • Patent number: 6509040
    Abstract: The present invention relates to fast dispersing solid dosage forms that preferably dissolve in the oral cavity within sixty (60), more preferably within thirty (30), most preferably within ten (10) seconds. A novel feature of the solid dosage forms according to the invention reside in the fact that the composition is essentially free or absolutely free of mammalian gelatin. It has been discovered that the use of certain modified starches at concentrations from 20 to 90% by weight of the solid dosage form prepares dosage forms that are mechanically and chemically stable and are able to deliver higher concentrations of an active ingredient than the heretofore utilized gelatin based fast dispersing solid dosage forms. Further, the solid dosage forms according to the invention are obtainable by removing a solvent, such as water, from a mixture comprising an active ingredient, a modified starch and a matrix forming agent via freeze drying.

  • Patent number: 6423342
    Abstract: A process for the preparation of a solid pharmaceutical dosage form comprising a carrier and, as active ingredient, a compound which exists, in solution, in an equilibrium between a free acid or free base form and a salt form, and for which there is a difference in volatility between the free acid or free base form and the salt form. The process includes the steps of solidifying a mixture of the compound and carrier in a solvent, and subsequently removing the solvent from the solidified mixture. A pH modifier is added to the mixture prior to solidification to shift the equilibrium to favor the less volatile form of the active ingredient.
