Embodiment 1
[0052] In this embodiment, the drug-loaded pellet core was prepared according to the prescription shown in Table 1 below and the operation steps described below:
[0053] Preparation:
[0054] Pass prasterone sulfate sodium through an 80-mesh sieve, weigh the sieved prasterone sulfate sodium and the blank ball core according to the prescription amount shown in Table 1, and use a centrifugal granulator and a fluidized bed to granulate respectively. After the granulation is completed, the drug-loaded pellet core is obtained.

[0066] ①Preparation of drug-loaded pellet core
[0067] prescription:
[0068] Prasterone Sulfate Sodium 200g
[0069] Blank ball core (sucrose ball core) 274g
[0070] 8% PVP-k30 solution (solvent is 90% ethanol) 150g
[0071] Preparation Process:
[0072] Pass prasterone sulfate sodium through an 80-mesh sieve, weigh the prescription amount, and pour it into the hopper of the centrifugal granulator. Pour blank pellet cores into a centrifugal granulator for granulation, set the air inlet pressure to 0.7 bar, atomization pressure to 2 bar, thimble pressure to 1 bar, feeding speed to 3 rpm, peristaltic pump efficiency to 10%, and turntable speed to 135rpm, spray 8% PVP-k30 solution (the solvent is 90% ethanol), and the drying temperature is 55°C. After the granulation is finished, about 480 g of drug-loaded pellet cores are obtained.
