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.

A controlled release pharmaceutical composition comprises (a) topiramate or a pharmaceutically acceptable salt thereof, (b) a first intelligent polymer component; and (c) a second intelligent polymer component having opposite wettability characteristics to the first intelligent polymer component. The polymer components are effective for controlled release of the pharmaceutically active substance from the composition.

The present invention is directed to compositions comprising topiramate and a sulfoalkyl ether cyclodextrin, and methods of making and using the same.

The present embodiments relate to topically delivered compounded medications. A transdermal cream may provide the effective topical administration of multiple medications simultaneously; may include low concentrations of local anesthetics, a NSAID, an anticonvulsant, and/or other active ingredients; and may include lidocaine, prilocaine, meloxicam, and lamotrigine and/or topiramate. Alternatively, the transdermal cream may include a lidocaine/prilocaine base cream to which is added a fine powder of one or more ground up medications to form a compounded medication. The compounded medication in powder form may be generated from grinding up tablets of NSAIDs, anticonvulsants, nerve depressants, antidepressants, muscle relaxants, NMDA receptor antagonists, opiate or opioid agonists, and/or other agents. The compounded medication in powder form may include meloxicam, lamotrigine, topiramate, other active ingredients, and DMSO or Sterile Water for Irrigation. In another aspect, the present embodiments relate to methods of compounding medications and transdermal creams or gels.
