[0052] Screening and inspection of important excipients
[0053] 1, the screening of stabilizer (calcium carbonate) (prescription and preparation process are the same as embodiment 2, only change light calcium carbonate crystal form)
[0054] After the raw material medicine is micronized, the texture is lighter. In order to make the mixing uniform, the use of heavy calcium carbonate was abandoned after investigation, and the light calcium carbonate with a very small particle size (average particle size 1 μm-3 μm) was selected for investigation. A variety of light calcium carbonate with different crystal forms (only the following three types are listed now: spherical calcium carbonate, flake calcium carbonate, and spindle calcium carbonate) were studied, and the dissolution behavior of the prepared samples in two dissolution media was determined. ...
