  • Patent number: 6030644
    Abstract: This invention relates to sustained-release granular preparations obtained by wet-granulating an aqueous suspension, which comprises a medicinal ingredient, a fine particulate polymer having an average particle size not greater than 50 .mu.m and a plasticizer, into granules and treating said granules at a temperature not less than the lower one of a minimum film-forming temperature and glass transition temperature of a mixture of said polymer and said plasticizer. This invention is also concerned with a process for the production of the sustained-release granular preparations. According to the present invention, granular preparations having an excellent sustained-release property and a high safety to the human body can be easily produced in a simple manner.
