Embodiment 1

[0035] The preparation of embodiment 1 compound tablet

[0036]

[0037] Preparation process: mix pentoxifylline and prucalopride with auxiliary materials microcrystalline cellulose and starch evenly, add appropriate amount of 15% starch slurry to make soft material, and then granulate through a 16-mesh sieve. Dry the wet granules at 60°C, pass the dry granules through a 16-mesh sieve for granulation, sieve out the fine powder in the dry granules, mix with magnesium stearate, and then mix with the dry granules, and press into tablets to obtain the product.

Embodiment 2

[0038] The preparation of embodiment 2 compound tablet

[0039]

[0040] Preparation process: except that the components are different, the preparation process is the same as that described in Example 1.
