  • NOVEL DRUG COMPOSITIONS AND DOSAGE FORMS OF TOPIRAMATE
    Publication number: 20070243254
    Abstract: The present invention is directed to novel drug compositions and dosage forms comprising said drug compositions. The drug compositions of the present invention comprise a pharmaceutical agent and a solubilizing agent. The drug compositions of the present invention are particularly advantageous for use with low solubility and/or low dissolution rate pharmaceutical agents. The present invention is further directed to methods for manufacturing of said drug compositions and dosage forms. The present invention is further directed to methods of treatment comprising administration of said drug compositions and dosage forms.

  • Formulations and dosage forms for controlled delivery of topiramate
    Publication number: 20040115262
    Abstract: Dosage forms and devices for enhancing controlled delivery of lowly soluble active agents including topiramate by use of a drug core composition that increases the solubility of the pharmaceutical agent are described. The present invention provides a drug core composition for delivering high doses of lowly soluble topiramate in solid oral drug delivery systems that are convenient to swallow, for once-a-day administration. The drug core composition contains topiramate, a surfactant and a carrier in ratios for optimal solubility and delivery.
