  • Patent number: 7160544
    Abstract: The invention provides a vaccine composition and a method of preparation including the steps of: forming a water-in-oil emulsion including an alginate in water, an oil, an antigen, and either (a) a cellulose ether and at least one nonionic surfactant or (b) a PEO-PPO-PEO triblock copolymer surfactant and at least one nonionic surfactant; followed by crosslinking the alginate in the emulsion with at least two cations selected from the group consisting of aluminum, barium, calcium, lithium, manganese, strontium, and zinc, to form antigen-containing, crosslinked alginate microparticles; and harvesting the microparticles. Another aspect of the invention is a method of vaccinating a vertebrate species including the step of administering to the species a vaccine composition prepared according to the method of the invention.

  • Publication number: 20060210625
    Abstract: An oral pharmaceutical composition, comprising one or more positively charged, highly water-soluble pharmaceutically active agents such as trospium chloride, and one or more polymers containing polarized oxygen atoms, whereby the active agent(s) form an ion-dipole interaction with the polymer(s) that may be used for an immediate release system, an extended release system or a delayed release system.

  • Publication number: 20050053653
    Abstract: The present invention is directed to the oral osmotic delivery of therapeutic compounds that have limited solubility in an aqueous environment due to inherent hydrophobicity or to saturation limitations in the core of the osmotic system. The present invention is suitable for the osmotic delivery of glipizide and other hydrophobic drugs, but runs the spectrum to other therapeutic agents with higher aqueous solubilities, yet having a solubility limitation in an osmotic dosage unit due to high drug load.
