Abstract

The invention discloses a pellet type omeprazole enteric capsule and a preparation method thereof. The pellet type omeprazole enteric capsule is a sustained-release preparation, and is composed of a capsule shell and evenly mixed omeprazole pellets received in the capsule shell; each omeprazole pellet is composed of a blank pill core, a main drug layer, an isolation layer and an enteric layer in order from inside to outside, wherein the weight of the main drug layer accounts for 15-60% of that of the blank pill core, the weight of the isolation layer accounts for 10% of the total weight of the blank pill core and the main drug layer, the weight of the enteric layer accounts for 28-32% of the total weight of the blank pill core, the main drug layer and the isolation layer; besides, the enteric layers of 40-60% of omeprazole pellets are further coated with pigment layers; the weight of the pigment layer accounts for 0.5-1% of the total weight of the blank pill core, the main drug layer, the isolation layer and the enteric layer; the diameters of the blank pill cores are 0.8-1.0mm; the granularity of the omeprazole pellets is 14-20 meshes; each capsule contains 15-30mg of omeprazole. The pellet type omeprazole enteric capsule has the advantages of good acid resistance, sufficient active ingredient release without delay, good stability and the like.

Description

technical field [0001] The invention relates to an omeprazole enteric-coated capsule and a preparation method thereof, in particular to a pellet-shaped omeprazole enteric-coated capsule and a preparation method thereof, belonging to the technical field of medicine. Background technique [0002] Omeprazole, its chemical name is: 5-methoxy-2-[[(4-methoxy-3,5-dimethyl-2-pyridyl)-methyl]-sulfinyl]- 1H-benzimidazole, molecular formula: C 17 h 19 N 3 o 3 S, molecular weight: 345.42. [0003] Omeprazole is a proton pump inhibitor that can effectively inhibit the secretion of gastric acid. It also has an inhibitory effect on pepsin secretion, does not significantly change gastric mucosal blood flow, and does not affect body temperature, gastric cavity temperature, arterial blood pressure, venous hemoglobin, arterial oxygen partial pressure, carbon dioxide partial pressure, and arterial blood pH. It is also effective for gastric and duodenal ulcers, reflux or erosive esophagiti...
