Embodiment 1

[0059] Preparation method of pharmaceutical composition containing bexarotene 1

[0060] Weigh 50 mg of bexarotene crystal type I, 88 mg of bexarotene and ligustrazine eutectic, and 100 mg of co-amorphous bexarotene and polyvinylpyrrolidone 1:1, and physically mix them uniformly according to conventional methods. get.

[0061] Preparation method of pharmaceutical composition containing bexarotene 2

[0062] Weigh 50 mg of bexarotene crystal type I, 440 mg of bexarotene and ligustrazine eutectic, and 500 mg of co-amorphous bexarotene and polyvinylpyrrolidone 1:1, and physically mix them uniformly according to conventional methods. get.

Embodiment 2

[0064] Preparation method of bexarotene and ligustrazine cocrystal 1:

[0065] According to the table below, take appropriate amounts of bexarotene and ligustrazine into a mortar, add an appropriate amount of organic solvent, manually grind for an appropriate time, and dry at high temperature. Its powder X-ray diffraction analysis was carried out, and its diffraction pattern was the same as figure 1 Consistent, indicating that the obtained sample is a co-crystal of bexarotene and ligustrazine.

[0066]

[0067] Preparation method 2 of bexarotene and ligustrazine cocrystal:

[0068] As shown in the table below, take an appropriate amount of bexarotene and ligustrazine into a ball mill jar, add an appropriate amount of organic solvent, select an appropriate ball-to-material ratio, set an appropriate rotation speed, grind for an appropriate time, and dry at high temperature. Its powder X-ray diffraction analysis was carried out, and its diffraction pattern was the same as f...

Embodiment 3

[0074] Preparation method of bexarotene and polyvinylpyrrolidone co-amorphous product 1:

[0075] According to the table below, take an appropriate amount of bexarotene and polyvinylpyrrolidone in a mass ratio of 1:1 and put them in a ball mill. Its powder X-ray diffraction analysis was carried out, and its diffraction pattern was the same as Figure 4 Consistent, indicating that the obtained sample is a co-amorphous product of bexarotene and polyvinylpyrrolidone.

[0076]

[0077] Preparation method 2 of co-amorphous substance of bexarotene and polyvinylpyrrolidone:

[0078] Take 3 parts of Bexarotene 20g, and weigh 4g, 20g, 100g of polyvinylpyrrolidone respectively according to the mass ratio of 5:1, 1:1, 1:5, put them into the ball mill respectively, and select the ball-to-material ratio of 6: 1. The rotation speed is 400 r / min, the grinding is stopped for 2 minutes every 15 minutes, and the ball is milled for 10 hours, 2 hours, and 0.5 hours, respectively, to obtain t...
