Abstract

The invention provides an aluminum-magnesium-aspirin tablet (II) and a preparation method thereof. The aluminum-magnesium-aspirin tablet (II) is a double-layer tablet composed of an aspirin layer and a buffer layer, raw materials of the aluminum-magnesium-aspirin tablet (II) comprise an aspirin layer composition and a buffer layer composition, and the mass ratio of the aspirin layer composition to the buffer layer composition is 0.8: 1.2-1.2: 0.8; and wherein in the aspirin layer composition, 80% w/w of aspirin is coated with a premixed coating agent. According to the aluminum-magnesium-aspirin tablet (II) provided by the invention, the content of free salicylic acid is below 0.41% through 6-month accelerated stability investigation and test, and the tablet is free of phenomena such as layering and good in stability.

Description

technical field [0001] The invention belongs to the field of pharmaceutical preparations, and in particular relates to an aluminum-magnesium-pirin tablet (II) and a preparation method thereof. Background technique [0002] Al-Mg-Pirin Tablets (Ⅱ) was first developed by the Japanese Lion Pharmaceutical Company, and was approved as an anti-platelet inhibitor in Japan on September 19, 2000, and was added in November 2005 for the treatment of Kawasaki disease. indications. The product name of the product on the market is "Buffalin compound ingot A81" (BUFFERIN). [0003] Each aluminum-magnesium-pirin tablet (Ⅱ) contains 81mg of aspirin, 22mg of heavy magnesium carbonate, and 11mg of aluminum glyoxate. The alkaline components heavy magnesium carbonate and aluminum glycolate can reduce the adverse stimulation of aspirin to the stomach, significantly reduce the incidence of gastrointestinal mucosal erosion and ulcer, and increase the absorption of aspirin. In addition, heavy mag...
