  • Patent number: 4863724
    Abstract: Galenic compositions containing an oral antidiabetic agent and having an improved release of active substance are provided, as well as processes for producing these compositions. The compositions are characterized in that the onset of the activity and the duration of activity are adapted to the particular needs of diabetics with regard to proper control of the metabolism and the associated proper release of insulin. A basic or acidic excipient in a solvent is added to the antidiabetic active substance in a quantity such that the active substance is made soluble, and then a solubilizing agent is added. Polyvinylpyrrolidone is dissolved as carrier in this solution, but the carrier may simultaneously serve as the solubilizing adjuvant. This solution is further processed with other excipients to form pharmaceutical compositions.

  • Patent number: 4758142
    Abstract: The invention is directed to a process and apparatus for dotting molding tools with droplets of liquid or suspended lubricant in the production of shaped articles in the pharmaceutical, food, or catalyst fields. Pressurized lubricant solutions or suspensions and pressurized gas are alternately passed through capillaries, in conjunction with alternating single-substance nozzles, in such a way that drops are formed on the nozzle surface, in between the jets of gas, and are then detached from this surface and directed to specific zones of pressing tools. The apparatus comprises fast-acting valves for the brief release of pressurized gases and lubricant liquids or suspensions. The delivery lines of a gas valve and a liquid valve combine upstream of a capillary, and single-substance nozzles are mounted at the end of the capillaries.
