  • Patent number: 6150410
    Abstract: Pharmaceutical formulations of acidic pharmacologic agents which demonstrate improved uniformity of release over the wide range of pH values encountered between the stomach and intestinal tract comprise an acidic pharmacologic agent dissolved or dispersed in a matrix comprising about 10 weight percent to about 40 weight percent of a a neutral water-swellable hydrophilic polymer and 20 weight percent to about 50 weight percent of an acid-soluble polymer which swells in water at pH values above about 5. A particularly preferred formulation comprises divalproex sodium. Also disclosed are pre-tablet granulations and process for preparing both the pre-tablet granulation and the tablet unit dosage form.

  • Patent number: 6046177
    Abstract: Sulfoalkyl ether cyclodextrin (SAE-CD) based controlled release pharmaceutical formulations are provided by the present invention. The present solid pharmaceutical formulations consist of a core comprising a physical mixture of one or more SAE-CD derivatives, an optional release rate modifier, a therapeutic agent, a major portion of which is not complexed to the SAE-CD, and an optional release rate modifying coating surrounding the core. The present formulations are advantageously easier to prepare than other SAE-CD based formulations in the art yet provide similar or improved effectiveness. The SAE-CD derivative is used to modify the bioavailability and/or rate of bioabsorption of therapeutic agents. Multi-layered, osmotic pump, coated, and uncoated tablet, minitablet, pellet, micropellet, particle, powder, and granule dosage forms are disclosed herein.
