摘要:
A catalyst for purifying exhaust gas comprising crystalline iridium silicate having a Si/Ir atomic ratio of 50 to 800 and a Si/Al atomic ratio of not less than 15. The catalyst exhibits excellent activity and selectivity when used for purification of, and specifically for eliminating NOx from, an exhaust gas which contains reducing components including hydrocarbons, oxygen in excess of the stoichiometric quantity necessary for completely oxidizing all of the reducing components, and nitrogen oxides. The catalyst is highly durable to hydrothermal aging.

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.
