Embodiment 1
[0017] Decoxyquinate 47.0g
[0018] Polyvinylpyrrolidone K30 47.0g
[0019] Polysorbate 60 6.0g
[0020] Preparation method and steps: add 47 parts of polyvinylpyrrolidone to 30 parts of water, stir and mix evenly, heat until completely dissolved, add 47 parts of decoquinate and 6 parts of polysorbate 60 to the ethanol solution of polyvinylpyrrolidone under stirring After mixing, a semi-fluid substance is obtained, which is ground by a colloid mill until it is completely mixed, then the material is dried under reduced pressure, crushed through a 120-mesh sieve, and the obtained solid is the decoquinate solid dispersion.
Embodiment 2
[0022] Decoxyquinate 16.0g
[0023] Polyvinyl alcohol 80.0g
[0024] Sodium Lauryl Sulfate 4.0g
[0025] Preparation method and steps: add 80 parts of polyvinyl alcohol into 60 parts of water, dissolve completely, add decoquinate into the aqueous solution of polyvinyl alcohol under stirring, then add sodium lauryl sulfate, and grind through a colloid mill Make the mixture uniform, dry under reduced pressure, remove all water, and pulverize into fine powder to obtain decoquinate dispersion.
Embodiment 3
[0027] Decoxyquinate 10.0g
[0028] Polyethylene glycol (4000) 85.0g
[0029] Polysorbate 80 5.0g
