Embodiment 1
[0055] Embodiment 1 prepares enteric-coated granules
[0056] prescription:
[0057]
[0058] Preparation:
[0059] Coating layer formula: polyacrylic acid resin 200g, ethyl cellulose 100g, polyethylene glycol 5g.
[0060] Color coat formula: 5% polyvinylpyrrolidone (PVP) solution 40g-200g, sunset yellow 1-2g, simple syrup 10-100g.
[0061] After mixing the raw and auxiliary materials of the prescription amount evenly, the soft material is made. Extrusion-spheronization pellets are made into pellets with a diameter of 0.1mm to 2.5mm. The extrusion speed is 1080r / min, the spheronization speed is 960r / min, and the spheronization time is 5min. Drug pellets, after drying in a fluidized bed, screen 30 mesh to 40 mesh pellets for coating, use polyacrylic resin 200g, ethyl cellulose 100g, polyethylene glycol 5g solution to coat the enteric coating layer, 5% polyethylene 40g-200g of pyrrolidone (PVP) solution, 1-2g of sunset yellow, 10-100g of simple syrup, coated with a color ...
