Abstract
Processes are provided for the preparation of orally administrable, yellow and powdery compositions essentially consisting of particles composed of a homogeneous mixture of an amorphous Cefditoren pivoxil substance with a water soluble high-molecular additive. These compositions can be produced by dissolving crystalline Cefditoren pivoxil substance and the water-soluble high-molecular additive in an aqueous solution of an acid, then neutralizing the resultant solution, to co-precipitate the product, and drying the thus precipitated product, followed by recovering the product in the form of the above-mentioned particles.
