DOSAGE FORMS FOR INCREASING THE SOLUBILITY AND EXTENDING THE RELEASE OF DRUGS SUCH AS E.G. TOPIRAMATE AND PHENYTON

摘要

Dosage forms and devices for enhancing controlled delivery of pharmaceutical agents by use of a drug core composition containing a polymer carrier (e.g. polyethylene oxide) and a surfactant (e.g. polyoxyl stearate, poloxamer) that increases the solubility of the pharmaceutical agent are described. The present invention provides a means of delivering high doses of lowly soluble drug in oral drug delivery systems that are convenient to swallow, for once-a-day administration. Osmotic devices are described.
