  • Publication number: 20110189259
    Abstract: The present invention relates to a pharmaceutical dosage form for transmucosal delivery of an active agent to two or more mucosal surfaces. The dosage form is presented as a transmucosal delivery device. The devices of the invention may include at least two mucoadhesive surfaces. The devices may further include an intermediate layer disposed between the mucoadhesive layers. The pharmaceutical can be incorporated in any one or all of the mucoadhesive layers or the intermediate layer. Upon application, the device adheres to at least two surfaces, providing transmucosal delivery of the drug to at least two surfaces.

  • Publication number: 20070148097
    Abstract: The present invention relates to a solid pharmaceutical dosage form for abusable drug delivery with reduced illicit abuse potential. The dosage form is presented as a bioerodable transmucosal delivery device that includes an abusable drug and an antagonist to the abusable drug associated with an abuse-resistant matrix. The devices of the invention may be in the form of a layered film or a tablet. Upon application in a non-abusive manner, the device adheres to the mucosal surface, providing transmucosal drug delivery of the drug with minimal absorption of the antagonist into systemic circulation.

  • Patent number: 6881482
    Abstract: Methods of making microcapsules and microcapsules comprising a core material and a shell material with substantially different dielectric constants and dissipation factors. Exposure to appropriate electromagnetic energy selectively (a) heats the core material with the higher dielectric constant and dissipation factor, directly or indirectly fusing the shell material and forming microcapsules, or (b) hardens polymerized shell material, which has a high dielectric constant and dissipation factor.
