Patents by Inventor David F. Erkoboni

David F. Erkoboni has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20020037324
    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.
    Type: Application

  • Patent number: 5858409
    Abstract: The present invention provides a method for preparing a spray-dried compressible granular formulation for preparing pharmaceutical tablets in which hydrolyzed cellulose is used as a granulation aid, the resulting granulations, and pharmaceutical tablets compressed from such granules. In these formulations there is employed from 1 to 97% by weight pharmaceutical active, from about 3 to 99% by weight 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.

  • Patent number: 5725886
    Abstract: A particulate co-processed unattrited microcrystalline cellulose:hydrocolloid composition wherein the respective components are present in a weight ratio of from about 99:1 to 70:30. The composition is useful as a spheronizing agent for producing spheroids of uniform size and sphericity and having high drug loadings. The composition is produced by drying a slurry of the microcrystalline cellulose in an aqueous solution of the hydrocolloid. The preferred hydrocolloid is methylcellulose.
