  • Methods for producing nateglinide B-type crystals
    Patent number: 7544834
    Abstract: A method for producing B-type crystals of nateglinide substantially free of H-type crystals is provided, which comprises drying solvated wet crystals of nateglinide at a low temperature until no solvent remains and making a crystal conversion thereof. According to this method, B-type crystals of nateglinide can be produced at an industrial scale without allowing other forms of the crystalline polymorphism to coexist.
    Type: Grant
    Filed: June 4, 2007
    Date of Patent: June 9, 2009
    Assignee: Ajinomoto Co., Inc.
    Inventors: Michito Sumikawa, Makoto Maruo, Kazuo Miyazaki, Shigehiro Nishina, Yukiko Matsuzawa
