Tablet formulation (1000 formulation unit amount):
* the particle size of the active component after being crushed is d90=43.0 μm; mannitol for regulating tablet weight to 200mg

(1) Pretreatment: pulverizing the active ingredients by a universal pulverizer, sieving with a 100-mesh sieve for later use, and sieving other auxiliary materials for later use;

as can be seen from the comparison of the table 2, the in vitro drug release of the drugs in the examples 1, 2 and 3 is mild, the drug release is about 15 to 20 percent in 1 hour, about 60 percent in 6 hours and about 95 percent in 12 hours, and the main drug is slowly released from the gastric retention tablets through dual mechanisms of diffusion and skeleton erosion. In comparative example 1, HPMC K100M is adopted alone, the drug release is incomplete, and a hard core still exists after 12 hours, probably because HPMC K100M belongs to a hydrophilic material with higher viscosity, and when the HPMC K100M is used in a large amount, the floating time of the tablet is ensured, but the drug release is retarded; in comparative example 2, no carnauba wax was used, and in the present invention, about 15% sodium bicarbonate was used, and bubbles were generated to help the floating of the tablet by the action of gastric acid, but the tablet without carnauba wax as a skeleton erosion material was easily broken due to the invasion of water and the impact of bubbles, and the dissolution of the tablet was rapidly increased, and the floating and sustained-release effects could not be maintained. In comparative example 3, sodium hydrogencarbonate was not used, the rising time was significantly prolonged, and the dissolution was insufficient. Comparative example 4 does not add the porogen polyethylene glycol 6000, also causes insufficient dissolution; in comparative example 5, inorganic salt NaCl is used as a pore-forming agent, which may cause that the water penetration speed is faster, so that the drug release is faster and the effect of slow and sustained release cannot be obtained; in comparative example 6, sodium alginate is used as a corrosion skeleton regulator, which may be a reason for hydrophobicity and viscosity, and causes the problem that the floating sheet is broken after 6 hours, so that the dissolution is increased rapidly; in comparative example 7, sodium lauryl sulfate is used as a foaming agent, the initial foam amount is insufficient, the rising and floating time is obviously prolonged, and in the later period, a layer of fine active agent bubbles are gathered on the surface of the tablet (the bubbles are large in amount and not easy to break), so that moisture is indirectly isolated, and the moisture enters the tablet core slowly and is not dissolved sufficiently.
The above results show that the product quality is better when the particle size range of the active ingredient is <200 μm d 90.
The above examples are only intended to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those of ordinary skill in the art that: modifications of the technical solutions described in the foregoing embodiments are still possible, or some technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
