preparation example Construction

[0099] The preparation method of concrete anti-AIDS compound preparation of the present invention comprises steps:

[0100] a) Zidovudine, lamivudine, nevirapine and internal excipients are pretreated (such as pulverized or sieved), wherein the internal excipients include disintegrants and optional fillers;

[0101] b) After mixing the pretreated zidovudine, lamivudine, nevirapine and internally added excipients (such as mixing in a wet granulator or mixer), the mixed material is obtained, and the mixed material is subjected to wet granulation (such as high-shear stirring granulation or one-step fluidized bed granulation) to obtain granulated materials;

[0102] c) After mixing the granulated material obtained in step b and the additional auxiliary materials, performing tablet compression or capsule filling treatment, thereby obtaining anti-AIDS compound tablets or capsules,

[0103] Wherein, the added auxiliary materials include lubricants, optional disintegrants and optiona...

Embodiment 1

[0129] Example 1 Tablet 1
