  • Process for time-controlled release of active ingredients
    Patent number: 4608248
    Abstract: The present invention provides a process for the timed control of the liberation of active material from a retarded active material-containing composition by the addition of a hydrophilic polymer, wherein the rate of liberation is adjusted by means of the viscosity of the added hydrophilic polymer, the rate of liberation increasing with increasing viscosity.
    Type: Grant
    Filed: February 24, 1986
    Date of Patent: August 26, 1986
    Assignee: Warner-Lambert Company
    Inventors: Adolf Knecht, Helmut Augart
  • Process for the manufacture of a pharmaceutical composition with a retarded liberation of active material
    Patent number: 4483847
    Abstract: The present invention provides a process for the production of a pharmaceutical composition with a retarded liberation of active material, wherein an active material in finely divided form is mixed with a finely divided high melting and a low melting lipid or lipoid component, the mixture is brought to a temperature which is above the melting point of the low melting component but below the melting point of the high melting component and the mixture, after melting of the low melting component, is allowed to cool to below the melting point thereof and subsequently worked up in known manner to give a finished pharmaceutical composition.
    Type: Grant
