  • Publication number: 20220331516
    Abstract: An intra-orifice medicament delivery system and formation method involve a housing defining an inner chamber extending along a longitudinal axis, with the chamber wall defining one or more openings therethrough. A retention arrangement extends from the housing, and is adapted to removably retain the housing within a bodily orifice defined by an orifice wall. An osmotic delivery device is disposed within the chamber and includes an osmogen portion and medicament-including portion disposed within a semipermeable membrane. The osmogen portion expands and applies pressure to the medicament-including portion in response to absorption of a liquid from within the bodily orifice permeating through the semipermeable membrane.

  • Patent number: 10729698
    Abstract: The present disclosure relates generally to sol-gel polymer composites that comprise chitosan, a hydrophilic polymer, a gelation agent, and optional additional ingredients in a suitable medium. Advantageously, the sol-gel polymer composite can form a durable seal or strong solid in response to one or more physiological stimulus. The disclosure further relates to medical and veterinary uses of the composite, particularly, methods and delivery systems for reducing or preventing the incidence of a mammary disorder in a dairy animal. More particularly, the disclosure includes methods and sol-gel polymer composite compositions for creating a physical barrier on the teat surface or in the teat canal or cistern of a non-human animal for prophylactic treatment of mammary disorders such as mastitis wherein the sol-gel polymer creates a seal in response to one or more physiological stimulus.

  • Patent number: 10561735
    Abstract: The instant invention relates to a solid product comprising a liquid biologically active agent which is intimately associated to a stabilizing agent; particularly a solid product that can be reconstituted to a clear, stable, stabilized nanodispersion or loaded micelles comprising a polymer as a stabilizing agent and a liquid, preferably water immiscible, biologically active agent. The instant invention is further directed toward a process for the production of the above solid product; particularly to micelles or nanodispersions produced by hydration of a cake or powder of the solid product, produced via an effective treatment of a stabilized solution comprising for example a polymer as a stabilizing agent, such as an amphiphilic block copolymer or a small molecular weight surfactant, loaded with a liquid biologically active agent, such as propofol, an optional additive, and a suitable solvent.
