Example Embodiment

[0041] Example:

[0042] According to the calculation of preparing 1000 pieces, the composition and proportion of raw and auxiliary materials are:

[0043] Cefditoren pivoxil 100g

[0044] Microcrystalline Cellulose 50g

[0045] Crospovidone 8g

[0046] Protein sugar 20g

[0047] 3% hypromellose solution

[0048] Magnesium Stearate 1g

[0049] Make 1000 pieces

[0050] Preparation:

[0051] ①The raw and auxiliary materials are passed through a 100-mesh sieve.

[0052] ②Weigh hypromellose, add water to make a 3% solution, and set aside.

[0053] ③Weigh the prescription amount of cefditoren pivoxil, microcrystalline cellulose, protein sugar and half of the prescription amount of crospovidone, mix well, add 3% hypromellose solution to make soft material, 20 mesh granulation , 60 ℃ blast drying, 24 mesh granulation, add the remaining crospovidone and magnesium stearate, and mix.
