Patent number: 4873080Abstract: Galenic compositions containing an oral antidiabetic agent and having an improved release of active substance as well as processes for producing these compositions are provided. 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 compositions.Type: GrantFiled: September 30, 1987Date of Patent: October 10, 1989Assignee: Dr. Karl Thomae GmbHInventors: Rolf Brickl, Gottfried Schepky, Eckhard Rupprecht, Andreas Greischel

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.Type: GrantFiled: July 23, 1987Date of Patent: September 5, 1989Assignee: Dr. Karl Thomae GmbHInventors: Gottfried Schepky, Rolf Brickl, Eckhard Rupprecht, Andreas Greischel
