Natural Gums, Resin Or Latex Patents (Class 424/485)
  • Patent number: 6106849
    Abstract: A "single-use" personal care product designed to replace conventional single use products such as small bars of soap, mini-bottles of shampoo, etc. A water soluble foamed polymer structure, such as produced by freeze drying acemannan derived from aloe vera, serves as the carrier for the personal care active ingredient, and provides the bulk to the structure. The dry foamed product has high void volume, good dimensional stability, high surface area, dissolves easily and completely upon exposure to water and hand mechanical action, and leaves no adverse residue on the skin. The product does not require bottling or complex wrapping, and is much more economical and environmentally friendly than the conventional single use products it replaces. The product can be conveniently carried in a purse or pocket, so that a consumer need never be without his/her favorite personal care products.

    Abstract: Process for the preparation of shaped, compressed controlled-release unit-dosage forms from a therapeutic active substance exhibiting a self-retarding release that depends on the magnitude of the force used for the compression. The process gives unit-dosage forms for which the release of the active substance is highly uniform, reproducibly identical and largely linear. To achieve this, the active substance and an additive charge that inhibits or compensates for the self-retardation of its release are processed into particles in the first stage of production, so that the preliminary compressed objects made from these particles without any further additives exhibit a rapid release (in comparison with the required controlled release) over the range of the force of compression envisaged for the production of the unit-dosage form in question, after which the particles are compressed in the second stage of production with a release-retarding agent to obtain the unit-dosage forms.

  • Patent number: 5837287
    Abstract: A process for the preparation of an oral solid rapidly disintegrating dosage form of a pharmaceutically active substance which has an unacceptable taste which process comprises forming a solution or a suspension in a solvent of a form of the pharmaceutically active substance which is less soluble in water and more palatable than the form with the unacceptable taste together with a water-soluble or water-dispersible carrier material, forming discrete units of the suspension or solution and removing the solvent from the discrete units under conditions whereby a network of the carrier material carrying a dosage of the less soluble and more palatable form of the pharmaceutically active substance is formed.

  • Patent number: 5811388
    Abstract: Pharmaceutical compositions for orally delivering a therapeutically effective amount of a drug to the colon without significant release of the drug in the upper GI tract after oral administration of the composition are described. The composition is a unit dosage in the form of a tablet that comprises about 0.01% by weight to about 10% by weight of the drug that is useful in treating a colonic disorder or that is absorbed from the colon; about 40% by weight to about 98% by weight of a hydrocolloid gum obtainable from higher plants; and about 2% by weight to about 50% by weight of a pharmaceutically acceptable binder. The compositions are useful for treating lower GI disorders in human subjects by administering a suitable amount to a subject in need thereof. A particularly preferred aspect is the process for preparing such composition in the form of a tablet.

  • Patent number: 5807581
    Abstract: Drugs are delivered in a sustained manner from an in vivo depot which is formed from a collagen-based injectable composition. The injectable composition is fluid when injected but undergoes crosslinking in situ to form a crosslinked collagen matrix which encloses the drug to be released. The composition also includes a flexible chain polymer which is similarly charged to the precrosslinked collagen. This flexible chain polymer is enclosed in the matrix as well when the matrix forms and alters the effective porosity of the matrix. The drug diffuses out of the matrix at a rate which depends upon the matrix's effective porosity.

  • Patent number: 5795581
    Abstract: A method for releasing molecules (guest molecules) from the matrix formed by the structure of another molecule (host molecule) in a controllable manner has been invented. This method has many applications in science and industry. In addition, applications based on such molecular systems may revolutionize significant areas of medicine, in particular the treatment of cancer and of viral infection. Similar effects can also be obtained by controlled fragmentation of a source molecule, where the molecular fragments form the active principle.

  • Patent number: 5744152
    Abstract: Release of an active ingredient can be controlled and the active ingredient can be protected from the environment during storage, by distributing it throughout a matrix containing a relatively large amount of polymeric material that is soluble and swellable in aqueous alkali but less soluble and swellable at a lower pH value and which is in the form of a dried oil-in-water emulsion of the polymer or a relatively insoluble partial salt of the polymer with a volatile amine, the full salt of the polymer being relatively soluble. The composition is of particular value for the protection of detergent enzymes.
