Beschreibung
Zusammenfassung:	The subject of present invention is to provide sustained-release fine particles and a preparation comprising sustained-release fine particles. The said sustained-release fine particles comprise supported material in which release of the supported material is controlled sufficiently; further, the supported material can be diffused sufficiently even if in a medium such as water; further having excellent property of sustained-releasing two different supported materials in the desired amounts respectively. The solution mean of the present invention is sustained-release fine particles and a preparation comprising sustained-release fine particles. The said sustained-release fine particles comprise supported material, microparticule-shape granules, and coating agent, wherein microparticule-shape granules have the average diameter in the range of 20 to 300 m.
