  • Patent number: 7204997
    Abstract: A responsive microgel is provided which responds volumetrically and reversibly to a change in one or more aqueous conditions selected from the group consisting of (temperature, pH, and ionic conditions) comprised of an ionizable network of covalently cross-linked homopolymeric ionizable monomers wherein the ionizable network is covalently attached to an amphiphilic copolymer to form a plurality of ‘dangling chains’ and wherein the ‘dangling chains’ of amphiphilic copolymer form immobile micelle-like aggregates in aqueous solution. A responsive microgel is further provided that comprises at least one therapeutic entity and delivers a substantially linear and sustained release of the therapeutic entity under physiological conditions.

  • Patent number: 7195778
    Abstract: The invention is directed to a drug delivery device for controlled release of a drug, comprising a core that has a cylindrical plug embedded therein; and a coating that at least partially surrounds the core. The core is comprised of a drug and excipients. The coating surrounding the core is essentially impermeable to the drug. The cylindrical plug, which is embedded in the core, may be hollow or solid. The drug delivery device enables zero-order drug release profiles as well as more complicated release profiles to be obtained. The invention is also directed to a method of making the drug delivery device.

  • Patent number: 7135194
    Abstract: Onychomycosis is a fungal infection of the nail bed and is difficult to treat topically because penetration of the nail plate is difficult, and systemic antifungal treatments are prone to side effects and drug interactions. The present invention treats onychomycosis by applying an antifungal composition to the nail bed directly using a solid, semi-solid, or flowable carrier. The carrier can be in the form of a semi-solid into which the user digs and scrapes the nail, a solid carrier can be inserted directly under the nail in contact with the nail bed, or a flowable composition can be injected in contact with the nail bed.

  • Patent number: 7119056
    Abstract: The invention relates to amphiphilic, non-ionic oligoesters that are free-flowing at an ambient temperature. Said oligoesters are produced by reacting dicarboxylic acid compounds, polyol compounds of water-soluble alkylene oxide addition products and optionally diol compounds. The invention also relates to detergent formulations and concentrates containing the aforementioned oligoesters and the use of oligoesters as additives in detergents, in particular for cleaning hard surfaces.
