Abstract

The invention discloses an esomeprazole magnesium enteric pellet capsule and a preparation method thereof. The esomeprazole magnesium enteric pellet capsule is formed by filling a capsule with enteric pellets, and each enteric pellet sequentially comprises a blank pellet core, a drug carrying layer, an isolating layer, an enteric layer and a protecting layer from inside to outside. Grain particle and pH value of active drug ingredients of each drug carrying layer are controlled, degradation caused by the fact that active ingredients are combined with acidic enteric coatings is prevented due to using of each isolating layer, adhesion of the enteric pellets is avoided due to using of each protecting layer, and fluidized bed coating technology is adopted, so that the esomeprazole magnesium enteric pellet capsule is high in stability and release degree, remarkable in gastric acid inhibiting effect and supportive of being widely applied in treatment of gastroesophageal reflux disease and digestive ulcer with positive helicobacter pylori. The preparation method is simple, low in production cost, environment friendly and suitable for industrialized production of the esomeprazole magnesium enteric pellet capsule.

Description

technical field [0001] The invention belongs to the field of pharmaceutical preparations. More specifically, the invention relates to an enteric-coated pellet capsule with esomeprazole magnesium as an active ingredient and a preparation method thereof. Background technique [0002] With the accelerated pace of modern life, people's diet rules cannot be guaranteed, and the incidence of stomach problems is getting higher and higher. Acute or chronic stomach problems will almost always occur to varying degrees in a person's life. Gastrointestinal diseases are common diseases and frequently-occurring diseases, and the total incidence rate accounts for about 20% of the population. The older you are, the higher the incidence rate is, especially the middle-aged and elderly people over 50 years old. It is more common in men than in women. If it is not treated in time, it will recur for a long time and easily transform into cancer. Gastrointestinal diseases have always been regarded...
