Embodiment 1
[0023] Get 1 kg of nifurofurol hydrazide and pulverize it, and cross a 600 mesh sieve to get nifurofarzide fine powder for subsequent use; get 0.01 kg of cyclamate and dissolve it with 2 kg of 95% ethanol to make cyclamate in ethanol; Put the above nifurofarzide fine powder in a blender, add ethanol solution of cyclohexanesulfonic acid, stir evenly, then add 2kg of 1000 mesh silicon dioxide micropowder, after fully stirring evenly, pass through a 200 mesh sieve to make a capsule core; Put the capsule core into a stainless steel interlayer pot with a stirring device, add 4kg of polyethylene glycol 4000 and stir evenly, heat the interlayer at 75°C to 80°C, melt it and stir it evenly, then immediately pour it into a metal plate in an ice-water bath , make it cool and solidify rapidly, put it into a desiccator to dry for 24 hours, and use a jet mill to make a powder with a particle size of 90 to 100 meshes to obtain the finished nifurofarzide microcapsule powder.
Embodiment 2
[0025] Get 1 kg of nifurofurol hydrazide and pulverize it, and cross a 600 mesh sieve to get nifurofarzide fine powder for subsequent use; get 0.015 kg of cyclamate and dissolve it with 2 kg of 95% ethanol to make cyclamate ethanol solution; Put the above nifurofarzide fine powder in a blender, add ethanol solution of cyclamate, stir evenly, then add 1 kg of 1000 mesh silicon dioxide micropowder, stir well, pass through a 200 mesh sieve to make a capsule core; Put the capsule core into a stainless steel interlayer pot with a stirring device, add 3kg of polyethylene glycol 6000 and stir evenly, heat the interlayer at 75°C to 80°C to melt and stir evenly, then immediately pour it into a metal plate in an ice-water bath , make it cool and solidify rapidly, put it into a desiccator to dry for 24 hours, and use a jet mill to make a powder with a particle size of 90 to 100 meshes to obtain the finished nifurofarzide microcapsule powder.
Embodiment 3
[0027] Get 1 kg of nifurofurol hydrazide and pulverize it, and cross a 600 mesh sieve to get nifurofarzide fine powder for subsequent use; get 0.02 kg of cyclamic acid and dissolve it with 2 kg of 95% ethanol to make cyclamic acid ethanol solution; Put the above nifurofarzide fine powder in a blender, add ethanol solution of cyclamate, stir evenly, then add 3kg1100 mesh silicon dioxide micropowder, after fully stirring evenly, pass through a 200 mesh sieve to make the capsule core; Put the capsule core into a stainless steel interlayer pot with a stirring device, add 6kg of polyethylene glycol 6000 and stir evenly, heat the interlayer at 75°C to 80°C, melt it and stir it evenly, then immediately pour it into a metal plate in an ice-water bath , make it cool and solidify rapidly, put it into a desiccator to dry for 24 hours, and use a jet mill to make a powder with a particle size of 90 to 100 meshes to obtain the finished nifurofarzide microcapsule powder.
