- the particle size of ecadotril used in the present invention is as small as possible because the dissolution rate becomes higher. Therefore, for example, the 50% average particle diameter is adjusted to 10 ⁇ or less, preferably 3 i in or less. If fine drug particles cannot be obtained by the crystallization process, it is preferable to increase the substantial surface area of the drug by pulverization using a pulverizer or the like by a conventional method in order to improve the dissolution rate.

- This ecadotril dispersion is pulverized with a wet pulverizer (sand mill) to prepare a suspension of ecadotril with a 50% average particle size of about 6 ⁇ m.
- sand mill wet pulverizer
- Croscarmellose sodium (Asahi Kasei: 1.5 g of Ac-Di-So and 0.15 g of magnesium stearate (St-Mg)) are added to 13.35 g of the fine granules and mixed to prepare tablet granules.
- 150 mg of the tablet granules are tableted with a static compressor at a pressure of 0.40 ton to obtain tablets having a diameter of 7.5 mm.

- a slug is tableted by a dry method according to a conventional method, and the tablet is crushed to prepare dry granules.
- Tablet granules are prepared by mixing 10.0 g of the dry granules and 0.125 g of magnesium stearate (St-Mg).
- the tablet condyle: 200 mg is tableted with a static compressor at a pressure of 0.45 ton to obtain a tablet with a diameter of 8.0 mm.

- the formulation (e.g., granules, powders, tablets, capsules, etc.) in which the rapid release microdispersibility of ecadotril is extremely enhanced by the improvement of the wettability of ecadotril and the synergistic effect with the disintegrant ) Can be obtained.
- a high content of ecadotril preparation can be obtained, especially by a spray drying method.
- ecadotril can be finely dispersed in primary particles before formulation without passing through large disintegrating particles. This formulation can facilitate the dissolution and absorption of ecadotril from the bile acid-rich duodenum to the upper small intestine due to the rapid microdispersion of ecadotril in the stomach.
