Patent number: 6274174Abstract: The present inventors have made studies for the purpose of establishing a process for preparing controlled-release preparations which can rapidly release 99% or more of a slightly soluble medicament (which has by itself shows a slow dissolution rate) in the upper part of the small intestine. As a result, the inventors have succeeded in establishing a process comprising carrying a slightly soluble medicament which has a slow intestinal dissolution rate on aggregates of the spherical microparticles of a multivalent metal alginate, in which each of the secondary particles (i.e., the aggregates) has a specific surface area ranging from 1 to 280 m2/g. This success leads to the accomplishment of the present invention.Type: GrantFiled: June 30, 1999Date of Patent: August 14, 2001Assignees: Nisshinbo Industries, Inc., Freund Industrial Co., Ltd.Inventors: Takeshi Hom-ma, Nagayoshi Myo, Takaya Sato, Hironobu Nanbu
