  • Patent number: 6860405
    Abstract: A container and storage apparatus with an attached, but functionally separate, labeling portion is provided. The apparatus has a primary chamber containing a predetermined agent separated from the labeling portion. An optional contamination barrier region may increase the separation. A preferred embodiment may be formed by a blow-fill-seal method from thermoplastic, allowing one piece molding of the apparatus. A removable cap allows a dispensing point to be opened into the primary chamber for removal of the agent. Indicia may be formed in or on the labeling portion, which may be smaller, larger, or the same in size and shape as the primary chamber. Inks, adhesives or other substances incidental to the indicia will be less likely to migrate across the apparatus wall and into the primary chamber due to the functional separation provided between the primary chamber and labeling portion.

  • Patent number: 6858725
    Abstract: Granulation of microcrystalline cellulose with a granulating fluid consisting of water and a water-miscible, volatile, polar organic solvent yields porous granules which are comprised of particles that are larger than the ungranulated microcrystalline cellulose. This granulated microcrystalline cellulose is capable of cushioning controlled release particles and barrier coated particles from the compression forces used in tableting, thereby maintaining the physical integrity of the components of the tablet.

  • Patent number: 6745546
    Abstract: This invention relates to a method and apparatus for forming soft capsules and provides novel processing flexibility. The apparatus comprises a three-way valve injector wedge. This injector wedge allows for set-up of the encapsulation machine with a placebo fill and quick change over to active fill. This conserves use of the active ingredient.

  • Patent number: 6726928
    Abstract: A process for the preparation of a rapidly disintegrating dosage form a pharmaceutically active substance which has an unacceptable taste wherein there is formed a solution or a suspension in a solvent of a form of the pharmaceutically active substance which is less soluble in water and more palatable than the form with the unacceptable taste together with a water-soluble or water-dispersible carrier material. Discrete units of the suspension or solution are formed and the solvent is removed from the discrete units under conditions whereby a network of the carrier material carrying a dosage for the less soluble and more palatable form of the pharmaceutically active substance is formed.

  • Patent number: 6720002
    Abstract: The invention herein relates to a pharmaceutical composition containing loratadine and derivatives thereof which is suitable for use in soft capsule dosage forms. A pharmaceutical composition according to the invention comprises loratadine and derivatives thereof in a pharmaceutically effective amount; and a solvent system comprising a mixture of medium chain fatty acids. The loratadine compositions exhibit good solubility and storage stability while maintaining bioavailability of the drug. The compositions also permit high concentrations of solubilized loratadine per total fill volume and thereby permit the use of smaller capsules to deliver the same dosage of drug.

  • Patent number: 6652880
    Abstract: This invention is directed to pharmaceutical compositions for oral administration, wherein the drug or active ingredient is known to have stability problems associated with the use of free fatty acids. The compositions of the invention enhance the solubility of such compounds and improve the storage stability thereof and can be advantageously used in soft-gel and hard-shell capsular formulations. The liquid pharmaceutical compositions, according to the present invention, have a drug dissolved in a liquid vehicle. The liquid vehicle comprising a glyceride of a long chain fatty acid and a lypophilic surfactant having an HLB of less than ten. The composition, according to the invention, is also substantially free of free fatty acids.

  • 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: 6530962
    Abstract: The invention herein provides for an improved dye composition for encapsulation in casing structures adapted for projectile motion and rupture upon contact with a target surface, such as paint balls. The dye composition adapted for use in an impact-rupturable capsule of the invention comprises a water-soluble dye and a lipophilic carrier having an oil and an emulsifier, said emulsifier comprising ethoxylated mono- and diglycerides. The invention further provides for an impact-rupturable capsule containing the dye composition. Advantages of the dye composition of the invention include improved consistency and reduced separation of ingredients; greater viscosity and thickness; greater “smearability” and splattering of dye on target surface upon impact and rupture of the casing; and greater water solubility and improved machine washability.

  • Patent number: 6511681
    Abstract: A formulation of a sparingly water-soluble, crystalline pharmaceutically active agent wherein the active agent is converted to and stabilized in its amorphous form as a solid solution of a normally hydrophobic vehicle is described. The amorphous state is stabilized by the composition of the formulation, providing long shelf life of the improved composition. This stabilized formulation also provides increased solubility and bioavailability of the active agent. Solutions of the active agent are stabilized by the composition, preventing recrystallization and precipitation of the less soluble, crystalline form of the active agent from aqueous solutions thereof.

  • Patent number: 6387400
    Abstract: The invention disclosed herein is a process for increasing the achievable concentration of a pharmaceutically active ingredient relative to fill composition viscosity for dosage units. The process is particularly useful in the preparation of soft gelatin capsules containing ibuprofen, naproxen, indomethacin, and acetaminophen, as the pharmaceutically active ingredient. As a result of the process, lesser quantities of composition ingredients other than the pharmaceutically active ingredient are needed to accomplish the same therapeutically effective dosage, thereby significantly increasing the concentration of the pharmaceutically active ingredient resulting in either a reduction in overall fill volume and dosage unit size or an increase in concentration of pharmaceutically active ingredient per dosage form.
