  • Patent number: 4708868
    Abstract: This invention is directed to novel galenic preparation forms for providing an oral anti-diabetic agent having an improved release of active substance and to processes for producing these preparation forms. The pharmaceutical 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 metabolism and the associated proper release of insulin. A basic or acidic excipient in a solvent is added to the anti-diabetically active substance in a quantity such that the active substance is made soluble, and then a solubilizing agent is added. The solution is applied to a water-insoluble carrier, the solvent is evaporated, and the residue is further processed to yield the various preparation forms.

  • Patent number: 4707309
    Abstract: The invention is directed to a process 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 form 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.
