Embodiment 1
[0069] An atorvastatin calcium tablet, comprising the following components in parts by weight: 5 parts of atorvastatin calcium with a particle diameter of 30-40 μm, 40 parts of starch, 1 part of povidone, and 20 parts of crospovidone , 1 part of magnesium stearate, 3 parts of polyethylene glycol-4000.
[0070] Atorvastatin calcium tablets are prepared by the following method:
[0071] (1) Mix atorvastatin calcium, starch, 10% magnesium stearate, and crospovidone, first stir at 50r / min for 5min, and then 200r / min for 10min to obtain substance A;
[0072] (2) Heating purified water to 40°C, adding povidone and polyethylene glycol-4000 according to a mass ratio of 1:3, to obtain substance B;
[0073] (3) Mixing substance A and substance B, passing through a 16-mesh sieve to obtain wet granules;
[0074] (4) Dry the wet granules at 40°C, control the moisture to <2%, pass through a 20-mesh sieve for granulation, and obtain dry granules;
[0075] (5) Add the remaining 90% magnesi...

[0077] An atorvastatin calcium tablet, comprising the following components in parts by weight: 15 parts of atorvastatin calcium with a particle diameter of 30-40 μm, 70 parts of mannitol, 5 parts of hydroxypropyl cellulose, and carboxymethyl starch 35 parts of sodium, 5 parts of sodium stearate fumarate, 8 parts of polyethylene glycol-6000.
[0078] Atorvastatin calcium tablets are prepared by the following method:
[0079] (1) Mix atorvastatin calcium, mannitol, 20% sodium stearate fumarate, and sodium carboxymethyl starch, first stir at 100r / min for 10min, and then stir at 300r / min for 20min to obtain substance A;
[0080] (2) Heating purified water to 50°C, adding hydroxypropyl cellulose and polyethylene glycol-6000 according to the mass ratio of 1:10, to obtain substance B;
[0081] (3) mix substance A and substance B, pass through a 18-mesh sieve, and obtain wet granules;
[0082] (4) Dry the wet granules at 60°C, control the moisture to <2%, pass through a 20-mesh siev...
Embodiment 3
[0085] An atorvastatin calcium tablet, comprising the following components in parts by weight: 5 parts of atorvastatin calcium, 40 parts of microcrystalline cellulose, 1 part of binder, 20 parts of disintegrant, 1 part of silicon dioxide , 3 parts of macrogol-4000, 1 part of aspartame.
[0086] The particle size composition of the atorvastatin calcium is as follows: 30-40 μm: 5-10 μm=3:1;
[0087] The binder is a mixture of gelatin and hypromellose, and the mass ratio of the two is 1:1;
[0088] The disintegrant is a mixture of croscarmellose sodium, microcrystalline cellulose and low-substituted hydroxypropyl cellulose, and the mass ratio of the three is 1:3:2; agent, the croscarmellose sodium is an internal and external disintegrant (the mass ratio of the croscarmellose sodium and external disintegrant is 1:1), and the low-substituted hydroxypropyl cellulose Su is an internal disintegrant.
[0089] Atorvastatin calcium tablets are prepared by the following method:
