Summary for Patent: 5,958,915
Title: | Antibacterial composition for oral administration |
Abstract: | A new, antibacterial composition for use in oral administration is now provided, which composition comprises a mixture of Cefditoren pivoxyl with a water soluble casein salt. This composition has a reduced bitter taste of Cefditoren pivoxyl and also has improved properties regarding the rate and concentration of dissolution of Cefditoren pivoxyl in water and a ratio of dissolution out of Cefditoren pivoxyl into water. This composition further can attain a high absorbability of the Cefditoren component at the digestive tubes upon oral administration thereof. In this composition, the ratio (by weight) of Cefditoren pivoxyl to the casein salt added may preferably be in a range of 1:0.1 to 1:4. By further addition of a water-soluble polyphosphoric acid salt to the composition, the composition can prevent a ratio of dissolution out into water of the Cefditoren pivoxyl component being decreased when the composition was stored under severe conditions. |
