[0034] The preparation of lansoprazole enteric-coated pellets is carried out in a fluidized bed granulation coating machine. The preparation process is coating of the main drug layer, coating of the isolation layer, coating of the neutral layer, and coating of the enteric layer;
[0035] Among them, 1) The specific operation of coating the main drug layer is as follows:
[0036] Take 20-40mL of purified water, stir, and slowly add 0.2-0.4g of anhydrous sodium carbonate as an acid-base regulator. -0.4 g polysorbate-80 is used as a solubilizer, and after dissolving completely, add lansoprazole in the dark, and stir into a uniform suspension; the blank ball core is placed in a fluidized bed granulation coating machine, and the boiling air volume 20-40 Hz, jet pressure 0.1-0.3 MPa, material temperature 35-40 ℃, spray speed 2.0-4.0 mL min -1 , the main drug layer coating pellet containing lansoprazole 20-40% is obtained;
[0037] 2) The specific operation of the isolation layer c...
