Aqueous film coating solution, and, film-coated granules, and, using this tablet

摘要

The present invention seeks to acid resistance and excellent sustained release, and has a flexibility which is suitable for tableting, and to provide an aqueous film coating solution such as productivity and economically advantageous. And ethyl acrylate-methyl methacrylate copolymer dispersion, methacrylic acid copolymer LD, a plasticizer, titanium oxide, containing water, aqueous film coating solution of the present invention, ethyl acrylate-methyl methacrylate copolymers are dispersion, methacrylic acid copolymer LD, plasticizers and solid mass ratio of the titanium oxide is 100: 40 to 100: 5 to 50: a 5 to 30, and the solid concentration of 5 to 20 mass%.
