  • Patent number: 5902606
    Abstract: Sparingly water-soluble active compounds, for example medicinal substances, are converted into the dissolved (molecularly disperse) state by dissolving them in a hydrophilic peptide having a molecular weight above 100 D, for example gelatin. The solubility both during storage and during use of the formulation by the user or patient is thereby ensured, without organic solvents or solubilizing agents which cause undesirable side effects being required.

  • Patent number: 5888515
    Abstract: A poison ivy (and related dermatitis) treatment composition and method in which a novel composition containing a combination of active ingredients gives new and unexpected results over compositions of the prior art. The inventive composition includes three essential ingredients: extract (fresh sap) of jewelweed (Impatiens species); fresh sap of plantain leaf; and an aqueous colloidal dispersion of subdivided whole oat grains. It is believed that the amphiphilic nature of the aqueous colloidal oat dispersion both preserves the activity of the plantain and jewelweed enzymes, as a result of its oat oil fraction, and also enhances topical delivery to the epidermis due to its aqueous fraction and the stabilizing effect of the oat bran as bulking agent.

  • Patent number: 5576021
    Abstract: A sustained-release multi-granule tablet is obtained by compressing sustained-release granules, which contains an active substance, and a formulation adjuvant. Each of the granules has been coated in advance with a layer of the formulation adjuvant and/or a layer of a mixture of the formulation adjuvant and the active substance. The tablet releases an active substance at a suitable velocity into the digestion tract, resulting in that the variability in the absorption of the drug in each patient and among individual patients is minimized to achieve maximum bioavailability.

  • Patent number: 5549914
    Abstract: Thermally stable collagen gels formed by the addition of small amounts of neutralized slightly cross-linked polyacrylic acid. Thermally stable gels resulting from 0.3 to 4.0 percent by weight of collagen and 0.10 to 0.50 percent by weight of neutralized slightly cross-linked polyacrylic acid. The thermally stable gels are useful in wound care management. Further, synergistic effects are noted by the addition of 0.5 to 3.0 percent by weight of natural gums, particularly those containing glucuronic acid segments. Gelatin, a partially hydrolyzed collagen, behaves in a similar manner to collagen.

  • Patent number: 5527540
    Abstract: In the pharmaceutical formulation of at least one alkali-sensitive active substance with an effervescent system, the carbonate component is embedded in at least one edible, organic acid and is preferably covered by said acid or by another acid. The active substance is embedded in at least one of the following compounds: an edible, organic acid, a higher alcohol, a hydrocolloid or a relatively long-chain polyvinylpyrrolidone, preferably covered with at least one of the stated compounds. The contact zone between active substance and effervescent system should have a pH of not more than 4.5. Both effervescent system particles and active substance particles, which are embedded or optionally covered in this manner, may be applied to carrier crystals of the same or another acid. The mixture is preferably pressed to give tablets. The acid provided for the embedding or covering may contain 0.1 to 3 mg of ethylenediaminetetraacetic acid per tablet.

  • Patent number: 5518986
    Abstract: The present invention provides an effective method for controlling foliage and root fungus infection in cultivated crops. A fungicide composition in the form of an aqueous formulation which is applied to pre-harvest crops contains ingredients such as pentachloronitrobenzene, sodium bicarbonate, sodium carbonate, potassium oleate, potassium octanoate and xanthan gum. The combination of potassium oleate, potassium octanoate and xanthan gum functions as an effective spreader-sticker medium for forming an adherent coating on plant foliage surfaces, and for saturating ground soil. The coating exhibits both immediate and long duration fungicidal activities.
