Embodiment 1
[0026] Alogliptin Benzoate Tablets (Specification: 12.5mg (calculated as alogliptin), 10,000 tablets in total)
[0027]
[0028] Preparation method:
[0029] (1) Weigh the raw material of alogliptin benzoate through micronization and pass through a 120 mesh sieve, mannitol, microcrystalline cellulose, hypromellose, cross-linked carmellose sodium pass through a 80 mesh sieve, stearin Magnesium acid is passed through a 40-mesh sieve for subsequent use.
[0030] (2) Take alogliptin benzoate, mannitol, microcrystalline cellulose, and croscarmellose sodium in the prescribed amount by weighing and mix them evenly, then add the adhesive soft material in the prescribed amount, and pass through a 20-mesh sieve. grain. The prepared wet granules are air-dried at 50-60°C.
[0031] (3) The dry granules are passed through an 18-mesh sieve for granulation, and the prescription amount of magnesium stearate is added and mixed evenly to obtain mixed granules.
[0032] (4) Determining the...
