[0047] Preparation process: solvent evaporation method
[0048] Dissolve febuxostat and povidone K30 in the prescribed amount in a solvent of acetone:methanol (1:3), volatilize under reduced pressure in a water bath at 60°C, vacuum degree 0.07-0.08MPa, and recover organic matter under reduced pressure. After the solvent becomes viscous, continue vacuum drying under reduced pressure for 1 hour, transfer to a vacuum drying oven, dry at 40°C for 48 hours, and pass through an 80-mesh sieve to pulverize to obtain a solid dispersion.
[0049] The prepared solid dispersion was added into the prescribed amount of microcrystalline cellulose pH102, croscarmellose sodium, ...

[0053] Preparation process: solvent evaporation method
[0054] Take the prescribed amount of febuxostat and povidone K30, dissolve them in a solvent of methanol:dichloromethane (4:1), put them in a water bath at 60°C, and vacuum the degree of 0.07-0.08MPa, and recover the organic solvent under reduced pressure. After becoming viscous, continue vacuum drying under reduced pressure for 1 hour, transfer to a vacuum drying oven, dry at 40°C for 48 hours, and pass through an 80-mesh sieve to pulverize to obtain a solid dispersion.
[0055] The prepared solid dispersion is added into the prescribed amount of microcrystalline cellulose pH102, crospovidone, sod...

[0059] Preparation process: solvent evaporation method
[0060] Dissolve the prescribed amount of febuxostat and povidone K30 in a solvent of acetone:dichloromethane (3:1), in a water bath at 55°C, with a vacuum of 0.07-0.08MPa, and recover the organic solvent under reduced pressure. After becoming viscous, continue vacuum drying under reduced pressure for 3 hours, transfer to a vacuum drying oven, dry at 60°C for 48 hours, and pass through an 80-mesh sieve to pulverize to obtain a solid dispersion.
[0061] The prepared solid dispersion is added to the prescribed amount of pregelatinized starch, low-substituted hydroxypropyl cellulose, sodium lauryl sulfate, a...
