[0038] In the second aspect, the embodiment of the present invention also provides a preparation method of metformin hydrochloride pharmaceutical composition, which comprises the following steps:
[0039] S1. Mix metformin hydrochloride, pregelatinized starch and mannitol evenly, add water to granulate.
[0040] Specifically include: first crush metformin hydrochloride to 100-120 mesh, then put metformin hydrochloride, mannitol, and pregelatinized starch in a wet granulator, mix for 5-6 minutes, add an appropriate amount of purified water, and granulate for 1-2 minutes . Wet sizing is carried out with a oscillating granulator, and the mesh number of the sieve is 12-14 mesh. Wet granules are placed in a high-efficiency boiling dryer, preheated at an inlet air temperature of 60-70°C for 10 minutes, and dried at room temperature to control the moisture content of the granules between 1.5% and 6.5%. The dried granules are sized in a swing granulator, and the mesh size of the sie...
