Abstract
PURPOSE: The titled tablet in which the layer containing acetylsalcylic acid and the layer containing an adsorbent are prepared separately, thus preventing the decomposition of the acetylsalicylic acid during the storage.
CONSTITUTION: A layer containing acetylsalicylic acid (Aspirin) or its derivative such as aluminum acetylsalicylate 1 and another layer containing an adsorbent such as silica gel, alumina or acid clay 2 are prepared separately. When necessary, additionally the third layer containing a mixture of an adsorbent and an antacid 3 is prepared. Then, they are combined together to form the tablet of acetylsalicylic acid. In order to reduce the affection of water, the adsorbent added contrally contains a large amount of water, so the decomposition of acetylsalicylic acid is promoted, when it is stood as a mixture with the adsorbent. Therefore, they are separated and the decomposition is reduced even when the tablet is stored under high-temperature and high-humidity conditions.
