Embodiment 2
[0067] The preparation of embodiment 2 fluoxetine hydrochloride capsule
[0068] Pick materials according to the types of materials designed in the recipe shown in Table 4, and operate according to the process control parameters in Table 5. The fluoxetine hydrochloride is pulverized, and the particle size distribution D90 is controlled at 20 μm to 100 μm; the pregelatinized starch and silica are passed through a 60-mesh sieve. Weigh the raw materials and excipients according to the design amount of prescription 1-3. Add the pregelatinized starch to the wet granulator, set the stirring speed of the wet granulator to 70 rpm to 100 rpm and the cutting speed to 1200 rpm to 1800 rpm, then start the wet granulator, and use the spray technique to add simethicone emulsion and water for granulation. Then use 6.0mm×6.0mm square-hole screen for wet granulation. After unloading, it is dried in a fluidized bed to measure the moisture content of the material. When the moisture content is l...
