    摘要: A lipid or other hydrophobic or amphiphilic compound (collectively referred to herein as “hydrophobic compounds”) is integrated into a polymeric matrix for drug delivery to alter drug release kinetics. In embodiments where the drug is water soluble, the drug is released over longer periods of time as compared to release from the polymeric matrix not incorporating the hydrophobic compound into the polymeric material. In contrast to methods in which a surfactant or lipid is added as an excipient, the hydrophobic compound is actually integrated into the polymeric matrix, thereby modifying the diffusion of water into the microparticle and diffusion of solubilized drug out of the matrix. The integrated hydrophobic compound also prolongs degradation of hydrolytically unstable polymers forming the matrix, further delaying release of encapsulated drug.

    摘要: Drugs, especially low aqueous solubility drugs, are provided in a porous matrix form, preferably microparticles, which enhances dissolution of the drug in aqueous media. The drug matrices preferably are made using a process that includes (i) dissolving a drug, preferably a drug having low aqueous solubility, in a volatile solvent to form a drug solution, (ii) combining at least one pore forming agent with the drug solution to form an emulsion, suspension, or second solution, and (iii) removing the volatile solvent and pore forming agent from the emulsion, suspension, or second solution to yield the porous matrix of drug. The pore forming agent can be either a volatile liquid that is immiscible with the drug solvent or a volatile solid compound, preferably a volatile salt. In a preferred embodiment, spray drying is used to remove the solvents and the pore forming agent. The resulting porous matrix has a faster rate of dissolution following administration to a patient, as compared to non-porous matrix forms of the drug. In a preferred embodiment, microparticles of the porous drug matrix are reconstituted with an aqueous medium and administered parenterally, or processed using standard techniques into tablets or capsules for oral administration.

    摘要: It has been discovered that the incorporation of fluorinated gases, especially a perfluorocarbon such as octafluoropropane, into synthetic polymeric microparticles, significantly enhances echogenicity as compared with microparticles having air incorporated therein. The microencapsulated perfluorocarbon is manufactured with a diameter suitable for the targeted tissue to be imaged, for example, for intravenous or oral administration. In one embodiment, bioadhesive microparticles are formed for enhanced imaging of mucosal surfaces.

    摘要: ACTH polymeric controlled release systems are described wherein the ACTH retains good biological activity and is released over an extended period of time following administration by injection. In the preferred embodiment, the ACTH polymeric microspheres are made using very cold temperatures to freeze the polymer-ACTH mixtures into polymeric microspheres with very high retention of biological activity and material. Sustained release of biologically active ACTH is achieved when the microspheres are tested in vitro, extending over a period of greater than one day to several months. Altered release can be achieved by inclusion of degradation modifiers, pore forming agents, and stabilizers of the ACTH.

    摘要: A receptacle for beverage containers is disclosed. The receptacle has a rigid bottom portion consisting of a plurality of framework members. A plurality of spring fingers extend generally vertically up from the bottom portion to secure at least the bases of the beverage containers. With this construction, the beverage containers are retained in a vertical position. The receptacle has side walls extending generally vertically upward from the bottom portion to define a generally open top for the receptacle. The side walls includes slots for the attachment of a handle so that the receptacle can be lifted. Each receptacle is designed so that it can be mechanically interlocked with the top or bottom of an adjacent identical receptacle.

    摘要: An apparatus for removing material from a biological solution consisting of a reactor chamber having an inlet and an outlet, a bioactive compound immobilized on particular supports within the reactor, means for retaining the particular supports within the reactor, means for recirculating the solution and the supports at a high flow rate within the reactor, and means for agitating or dispersing the recirculating solution-support mixture throughout the reactor chamber so as to prevent packing of the supports while not subjecting the solution to excessive or damaging forces.In the given example, an apparatus for the extracorporeal removal of heparin from blood is provided. Heparinase is immobilized on cross-linked agarose beads recirculated at a high flow rate through the reactor. Agitation of the blood-bead mixture sufficient to prevent packing of the beads within the reactor chamber is provided by means of a series of openings in the recirculation tube dispersing the mixture throughout the chamber.
