Example Embodiment

[0054] Example 1. The prescription of flupirtine maleate capsules:

[0055]

[0056] Process:

[0057] 1) Pass the calcium hydrogen phosphate through a 100-mesh sieve and set aside;

[0058] 2) Crush flupirtine maleate through a 600 mesh sieve for use;

[0059] 3) Mix flupirtine maleate, calcium hydrogen phosphate, 10g silicon dioxide, and 10g magnesium stearate evenly;

[0060] 4) Put the above-obtained materials in a dry granulator to make dried materials, and crush them into dry granules by a swing granulator;

[0061] 5) Pass the obtained dry particles through 24 mesh and 80 mesh stainless steel screens in sequence, and collect the upper part of the 80 mesh screen as qualified particles;

[0062] 6) Add additional auxiliary materials crospovidone, 10g silicon dioxide, 3g magnesium stearate to the above materials, and mix them evenly;

[0063] 7) Fill the capsule.
