Patent number: 5204087Abstract: A composition for foaming preparation comprising (a) an organic acid of which the crystal surface is coated with a sugar and (b) a carbonate is disclosed. In the composition, an organic acid is completely shut off from a carbonate by a sugar coating so that the acid does not react with the carbonate over a prolonged storage time. When the composition is put into mouth, the sugar which covers the acid is readily dissolved, allowing the acid and the carbonate to react and to generate carbon oxide gas. An excellent foaming calcium preparation can be produced by using calcium carbonate as the carbonate or by adding other salt of calcium to the composition. Such a calcium preparation gives a good taste and favorable feeling upon administration. It is especially suitable for regular administration of calcium over an extended period of time.Type: GrantFiled: December 12, 1991Date of Patent: April 20, 1993Assignee: SS Pharmaceutical Co., Ltd.Inventors: Masami Moroi, Kimie Ominato, Toshio Yokoyama, Akira Iwasa
