摘要:
An objective of the present invention is to provide a cefditoren pivoxil pharmaceutical preparation which can safely be administered to a patient and not only improves wettability of cefditoren pivoxil, but also further improves absorbability through the intestinal tracts by maintaining amorphous particles having a high oral absorbability in a liquid for a long period of time. The present invention is a pharmaceutical composition comprising amorphous cefditoren pivoxil and a sucrose fatty acid ester, which is obtainable by mixing or wet-granulating particles containing amorphous cefditoren pivoxil with the sucrose fatty acid ester while amorphous cefditoren pivoxil maintains its particle state.
