Abstract

The invention discloses an esomeprazole enteric coated pellet preparation and a preparation method thereof. Particularly, the esomeprazole enteric coated pellet preparation is prepared from the following parts including a hollow pellet core, a drug loading layer, an isolation layer and an enteric coated layer, wherein the drug loading layer is prepared from the following raw materials including esomeprazole trihydrate, an adhesive and a drug loading layer solvent; the isolation layer is prepared from the following raw materials including a polymer material, a lubricant, an acid and alkali regulator and a drug loading layer solvent; the enteric coated layer is prepared from the following raw materials including a film forming agent, a plasticizer, a lubricant, a sunscreen and a drug loading layer solvent. The preparation method of the esomeprazole enteric coated pellet preparation sequentially comprises the following steps: 1) coating the drug loading layer; 2) coating the isolation layer; and 3) coating the enteric coated layer. With the optimization of a formula and a technology, the preparation method is capable of improving the coating efficiency, reducing the coating time and preventing the manpower and material resource waste. The prepared enteric coated pellet preparation is capable of improving the stability of a medicament and the medicine taking compliance of a patient, is more suitable for the patient to use and can be further processed into an oral preparation such as a capsule or a tablet.

Description

technical field [0001] The invention belongs to the technical field of pharmaceutical preparations, and relates to a pharmaceutical preparation with esomeprazole magnesium as an active ingredient, in particular to an esomeprazole magnesium enteric-coated pellet preparation and a preparation method thereof. technical background [0002] Esomeprazole is the left-handed isomer of omeprazole, the world's first single-isomer proton pump inhibitor (PPI) developed by AstraZeneca, which mainly inhibits gastric parietal cytoplasmic Sub-pump, thereby reducing gastric acid secretion to treat gastroesophageal reflux disease (GERD), Helicobacter pylori (HP) positive peptic ulcer and digestive system disorders related to gastric acid. In 2002, the original research company launched the replacement product of omeprazole——esomeprazole. Compared with omeprazole, it has a lower liver metabolism rate, higher blood concentration and bioavailability, and is acid-suppressing. The effect is stron...
