  • Patent number: 5424076
    Abstract: The invention concerns a method for the production of microscopic particles made of hydrolytically decomposable polymers, in particular copolymers, and containing active substances, using fluid gas with a uniform particle-size distribution and by the addition of biologically compatible amino acids. The microscopic particles produced by this method can be used as drugs for the treatment of humans or animals.

  • Patent number: 5398405
    Abstract: A device for producing a micro connection element 24, 30, the device comprising a cylindrical outer sleeve 1, a cylindrical central element 2 arranged coaxially in the outer sleeve 1, a plurality of cylindrical spacers 3 arranged between the outer sleeve 1 and the central element 2; the spacers 3 respectively arranged between two neighboring assembly elements 4 which are in contact with the neighboring spacers 3, the central element 2 and the outer sleeve 1; the assembly elements 4 can be microplug pins having a length such that they extend out of the arrangement comprising outer sleeve 1, central element 2 and spacers 3 so that the pins can support sleeves for making a microcoupling or female connection element, or the assembly elements 4 can be bushes into which microplug pins can be inserted, with a sleeve being joined to the outer end of each pin for receiving an electric wire, to thereby make a microplug or male connector; the microcoupling and microplug can be used on the ends of an electric supply lead

  • Patent number: 5393529
    Abstract: The present invention relates to active substance plasters for the controlled release of active substances to the skin consisting of a backing layer, an adhesive film connected therewith which film is water-soluble and consists of pressure-sensitive adhesive which comprises water-swellable polymers and in which the active substance is at least partially soluble, and of a removable protective layer covering the adhesive film, in which plasters the pressure-sensitive adhesive is based on homo and/or copolymers with at least one derivative of the acrylic or methacrylic acid, and which comprise as active substances, partially or completely dissolved in the adhesive, at a concentration of 0.5 to 10.0%-wt estrogens and their pharmaceutically acceptable derivatives alone or in combination with gestagens.

  • Patent number: 5284872
    Abstract: New organic nitrate compounds, formed by condensing a nitrato alkanoic acid with a sulfur-containing amino acid or peptide followed by the reaction of the resulting product with an amino acid, N-acylamino acid, peptide or an N-acyl peptide to produce a thio ester thereof, which prevent nitrate tolerance or overcome existing tolerance and which are useful for the treatment of cardiac diseases including circulatory diseases, coronary dilation, high blood pressure, cardiac insufficiency and for dilating the peripheral vessels.

  • Patent number: 5043280
    Abstract: A sterile product containing a substance embedded in a carrier is produced by use of a supercritical gas. In one embodiment, a mixture is formed of a substance, carrier and supercritical gas such as nitrous oxide or carbon dioxide, and the supercritical gas is separated from the substance and carrier to obtain the product. In another embodiment, the supercritical gas contains the substance, and is mixed with an atomized organic solvent containing the carrier to form a mixture. The supercritical gas extracts the solvent, and is separated from the substance and carrier to produce the product. Alternatively, the carrier can be in the supercritical gas and the substance in the solvent, or both the substance and carrier can be in the solvent. Atomization and formation of the mixture can be carried out by feeding the supercritical gas and solvent through a nozzle into a spray tower or column.
