TOPIRAMATE COMPOSITIONS AND METHODS OF ENHANCING ITS BIOAVAILABILITY

摘要

The present invention is directed to pharmaceutical compositions that allow for once- daily or alternate day dosage forms of topiramate. The proposed delayed/extended release single dosage form is equivalent to the immediate-release multiple dose daily regimen, and upon administration, provides steady state blood levels of topiramate. Formulations with increased bioavailability and improved pharmacokinetics are disclosed. A once-a-day administration of topiramate is advantageous over the multiple dose regimen both in terms of patient compliance and reduced adverse events, thus providing better treatment of the conditions for which the topiramate is indicated.
