preparation example Construction

[0023] A preparation method of cyclobenzaprine sustained-release tablet, comprising the following steps:

[0024] (1) get cyclobenzaprine and filler to mix evenly by weight percentage, take 85% ethanol as binding agent, make soft material, 20-24 mesh sieve granulation;

[0025] (2) Add surfactants and lubricants to the granules prepared in step (1), mix well, press into tablets, and dry to obtain cyclobenzaprine sustained-release tablets.

Embodiment 1-6

[0026] The preparation of embodiment 1-6 cyclobenzaprine sustained release tablet

[0027] According to the raw and auxiliary materials in the following prescription, the cyclobenzaprine sustained-release tablet is prepared according to the above-mentioned preparation method. Among them, " / " means not used.

[0028]

Embodiment 7-11

[0034] Example 7-11 Preparation of Cyclobenzaprine Sustained Release Tablets

[0035] According to the raw and auxiliary materials in the following prescription, the cyclobenzaprine sustained-release tablet is prepared according to the above-mentioned preparation method.
