  • Publication number: 20140205650
    Abstract: The invention relates to coating of suppositories containing free unsaturated fatty acid, fatty acid ethyl ester and fatty acid monoglyceride that are susceptible to oxidative degradation. The coating retards oxidative degradation of unsaturated fatty acids and gives the suppository a non-oily and smooth surface. The coating will enhance the shelf-life of the suppository and allow their storage at room temperature for extended time period. The coating may or may not contain medicament such as local anesthetic or steroid. According to this invention chemically unstable fatty acids in coated suppositories can be used to stimulate the process of defecation or to treat disorders such as hemorrhoids, bacterial infections, viral infections and inflammations, as well as against fissura ani and pruritus ani. Furthermore, coating suppositories, that contain high concentrations of free fatty acids, can reduce acid induced rectal irritation.

  • Patent number: 8217219
    Abstract: A vaginal insert formed from a composition that, prior to introduction to the vagina, has the physical properties of a liquid, semi-soft gel, paste, foam, or viscous material so that it can be effectively delivered to the vaginal canal. After introduction into the vagina, the composition will expand and/or solidify into a semi-solid or solid structure to substantially fill the entire “H” shaped space of the vagina and a portion of the rugal folds along the length of the vaginal canal. Upon solidifying, the composition defines an insert that, in one embodiment, is suitable for use as a tampon and, in another embodiment, is suitable for use as an incontinence device.

  • Publication number: 20120093911
    Abstract: The present invention provides improved intravaginal drug delivery devices, i.e., intravaginal rings, useful for the prophylactic administration of an antimicrobial compound, e.g., Dapivirine, to a human. The intravaginal rings of the invention address previous stability issues by utilizing a platinum catalyst (e.g., in the form of a platinum-siloxane complex) for the cross-linking reaction. The vaginal rings surprisingly achieve relatively high and steady release rates in vivo with a matrix ring containing a relatively small loading dose. While the matrix rings of the present invention have in vivo the steady release rates associated with reservoir rings, they are easier and less expensive to manufacture. The present invention also provides methods of blocking DNA polymerization by an HIV reverse transcriptase enzyme, methods of preventing HIV infection in a female human, methods of treating HIV infection in a female human, and methods of preparing platinum-catalyzed intravaginal rings.

  • Patent number: 8138265
    Abstract: A dihydroxyphenyl cross-linked macromolecular network is provided that is useful in artificial tissue and tissue engineering applications, particularly to provide a synthetic macromolecular network for a wide variety of tissue types. In particular, artificial or synthetic cartilage, vocal cord material, vitreous material, soft tissue material and mitral valve material are described. In an embodiment, the network is composed of tyramine-substituted and cross-linked hyaluronan molecules, wherein cross-linking is achieved via peroxidase-mediated dityramine-linkages that can be performed in vivo. The dityramine bonds provide a stable, coherent hyaluronan-based hydrogel with desired physical properties.
