  • Patent number: 7052719
    Abstract: 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.

  • Patent number: 6413550
    Abstract: Improved proteinoid carriers and methods for their preparation and use as oral delivery systems for pharmaceutical agents are described. The proteinoid carriers are soluble within selected pH ranges within the gastrointestinal tract and display enhanced stability towards at least one of photolysis or decomposition over time. The proteinoid carriers are prepared from proteinoids having between 2 and 20 amino acids and having a molecular weight of between about 250 and 2400 daltons.

  • Patent number: 6409989
    Abstract: Injectable activated carbon suspensions are proposed for the presurgical marking of nonpalpable mammary pathologies for the purpose of achieving better diagnosis and treatment. These are suspensions that flow freely and without the formation of obstructing aggregates in the needles used during their application, with carbon particles of micron granulometry limited to less than 50&mgr; and preferably between 2&mgr; and 6&mgr; in concentration of approximately 4.0% p/v in saline aqueous medium. A process is also proposed for preparing said compositions.

  • Patent number: 6410481
    Abstract: The invention relates to water-dispersible granules of a pesticidally active main component of sufficiently high melting point, a liquid pesticidal active substance or pesticidal active substance of low melting point and/or which is not sufficiently biologically active in the solid state, in dissolved form, a solvent or solvent mixture with low volatility, and, if appropriate, further additives or adjuvants. The granules are prepared from an aqueous suspoemulsion of the components by removing the water, for example in a fluidized-bed drier. The novel granules are distinguished by an outstanding spontaneous dispersibility and a good biological activity of the formulations prepared from them.

  • Patent number: 6375969
    Abstract: This invention relates to certain natural diatomaceous earth granule compositions which can be broadcast, i. e., dry spread on the soil to deliver a pesticide or fertilizer. The granules retain their physical integrity when spread, and have the unique property to spontaneously disintegrate when irrigation water is applied or rainfall hits the particle. Upon wetting, the particle disintegrates (blooms) to cover the soil surface. This bloom can cover an area many times the original area covered by the granule. The granules have high loadings of the diatomaceous earth, i.e. from about 35 to about 95 weight percent and contain from about 5 to about 40 weight percent of a surfactant system which exhibits excellent disintegration; rewetting and binding properties. Bioactive compounds can be loaded at up to 60 weight percent of the granule. Bioactive compounds may be formulated products or technical grades and may be homogeneously distributed throughout the granule or spray impregnated onto the granule.
